SDL just got an API to toggle VSync without having to tear down the
renderer ( libsdl-org/SDL#4157 ). We can remove the workaround and use
that instead. For now, we are putting it behind an ifdef until SDL
2.0.18 officially releases in November.
Fixes#831.
This makes it so it's not even possible to stay on the TELEPORTERMODE
screen by opening the map while it's being brought down. It also makes
it so the map animation is able to be canceled when being brought up
just by opening the map and closing it.
Fixes#833.
This is a pretty hefty commit! But essentially, I made a new editorclass
object, and moved all functions and variables that only get used in the
in-game level editor to that class. This cleanly demarcates which things
are in the editor and which things are just general custom level stuff.
Then I fixed up all the callers. I also fixed up some NO_CUSTOM_LEVELS
and NO_EDITOR ifdefs, too, in several places.
This accompanies the editor.cpp -> CustomLevels.cpp change; I'll be
splitting out the editor functions in the next commit. The name of the
include guard has been changed as well, but not anything else.
The game will freeze the player immediately if they release a
directional button within 3 frames of pressing it. Similar to flipping,
this involves global state, and will only apply to the first player
entity.
Closes#484
Flipping only applies momentum to the player entity currently being
processed. This normally wouldn't be a problem. However, flipping
involves global state, and only one flip can occur per frame. This means
that additional player entities don't get this boost of momentum, which
feels somewhat unnatural during gameplay.
This commit fixes this by splitting flip logic out of the loop over
player entities, and applying the flip momentum to all player entities.
To match the option to nuke all main game save data, there is also now
an option to nuke all custom level save data separately (which is just
all custom level quicksaves, along with stars for level completion). It
has its own confirmation menu too. It does not delete any levels from
the levels folder.
Custom level quicksaves are NOT affected by the clear data menu, so the
player should be able to delete quicksaves this way. The quicksave
confirmation menu now has an extra option to delete the save (and that
option also has its own confirmation menu before deleting).
It's possible to get one page of levels by removing all the built-ins,
either by removing them directly from data.zip or by putting files with
the same filenames as them in your level folder that don't contain
nothing.
And hey, there's already a check for if no levels exist at all, so why
not check for this too?
If a zip file is improperly structured, a message will be displayed when
the player loads the level list.
This will only display the last-displayed improper zip, because there
only needs to be one displayed at a time. Also because doing anything
more would most likely require heap allocation, and I don't want to do
that.
Some people prefer the 2.2 behavior where unfocusing pauses the game,
but the music still plays. One such person is Trinket9 on the VVVVVV
Discord server, who wanted it that way.
The reason audio pausing was added in the first place was to prevent
desyncing music in levels with cutscenes that synced to music. Rather
than reverting it, let's add this option instead.
This is because the fade delay did not last long enough.
I was under the mistaken impression that the fade animation lasts for 15
frames. However, this does not account for the fact that the offset of
each fade bar is dependent on RNG, and the worst case scenario is that
they have an offset of 96 pixels (in the opposite direction of the
fade).
The actual fade animation timer accounts for the worst case scenario, so
the fade animation actually lasts for (320 pixels plus 96 pixels is 416
pixels, 416 pixels divided by 24 pixels per frame equals 17.333...
frames, but since the actual timer keeps adding/subtracting 24 pixels
per frame until it passes the 416-pixel threshold, that gets rounded up
to...) 18 frames.
And an extra frame to make it so deltaframe interpolation doesn't
suddenly stop on the last deltaframes before the screen is completely
black.
I also need to draw the screen black on the map screen when glitchrunner
mode is off, if there's a fadeout going on. Else that would introduce
yet another frame flicker.
Previously, turning glitchrunner mode on essentially locked you to
emulating 2.0, and turning it off just meant normal 2.3 behavior. But
what if you wanted 2.2 behavior instead? Well, that's what I had to ask
when a TAS of mine would desync in 2.3 because of the two-frame delay
fix (glitchrunner off), but would also desync because of 2.0 warp lines
(glitchrunner on).
What I've done is made it so there are three states to glitchrunner mode
now: 2.0 (previously just the "on" state), 2.2 (previously a state you
couldn't use), and "off". Furthermore, I made it an enum, so in case
future versions of the game patch out more glitches, we can add them to
the enum (and the only other thing we have to update is a lookup table
in GlitchrunnerMode.c). Also, 2.2 glitches exist in 2.0, so you'll want
to use GlitchrunnerMode_less_than_or_equal() to check glitchrunner
version.
This fixes a regression where you're unable to activate activity zones
in in-editor playtesting if your interact button is not separate from
the map button.
When I originally did #743, I didn't have an option to set the bind to
be non-separate, so I removed this logic without adding a
game.separate_interact check. But when I added the option, I overlooked
this code, and so this regression happened. Whoops.
This fixes a regression where you're able to start flipped by restarting
and then holding ACTION.
This happens because when the game resets all variables, it turns
hascontrol back on (because of hardreset()). However, this is handled in
the input function, and it's handled before player input is handled, so
the player is able to get 1 frame of being able to flip after a time
trial resets.
Why didn't this happen in 2.2? Because resetplayer() in 2.2 would set
lifeseq to 10, as if the player had died. However, this is inconsistent,
because loading in to the game for the first time would not result in a
lifeseq of 10. So, in 2.2, restarting the time trial would remove that 1
frame of being able to flip because of lifeseq, while 2.3 doesn't set
lifeseq because the player hasn't died.
I could have fixed this by setting lifeseq in the time trial restart
code, but I decided to just set hascontrol to false instead.
Fixes#770.
The game automatically writes settings to disk after any other setting
is changed, so it should do the same whenever the user changes
controller keybinds.
This is a lot of copy-pasted code, but a little bit of copy-pasting
never hurt anyone...
The keybind to interact with activity zones and teleporters is now
separate from the keybind to open the map, or return to the editor from
in-editor playtesting, or restart a time trial. The keybind is now E,
and the default controller bind is X. No controller button prompts, but
the game didn't have controller button prompts anyways, so whatever.
Doing this now because if people's muscle memory are going to be broken
by not being able to spam the map keybind anymore, at least we can help
a bit by changing the keybind so they can keep spamming it - their
muscle memory is going to be broken anyways.
This option has to be enabled by going to the speedrunner menu options
and selecting "interact button". It is disabled by default.
All prompt text needs to be string-interpolated every time they are
drawn, because it is possible for people to change which interact button
they use in the middle of gameplay, via the in-game options.
Closes#736.
This is a small quality-of-life fix in the same vein as allowing the
player to press Esc in the teleporter menu (which they weren't able to
do in 2.2, either).
When you enter the Super Gravitron, you have to wait until the Super
Gravitron actually starts before being able to press Enter to return to
the Secret Lab. This is annoying if you just want to get back to the
Secret Lab. So, I've made it so the press-Enter-to-return functionality
is enabled from the moment that the Super Gravitron starts.
It turns out, despite the game attempting to prevent you from using
invincibility or slowdown in the Super Gravitron by simply preventing
you from entering the Secret Lab from the menu, it's still possible to
enter the Super Gravitron with it anyways. Just have invincibility or
slowdown (or both!) enabled, enter the game normally, and talk to
Victoria when you have 20 trinkets, to start the epilogue cutscene.
Yeah, that's a pretty big gaping hole right there...
It's also possible to do a trick that speedrunners use called
telejumping to the Secret Lab to bypass the invincibility/slowdown
check, too.
So rather than single-case patch both of these, I'm going to fix it as
generally as possible, by moving the invincibility/slowdown check to the
gamestate that starts the Super Gravitron, gamestate 9. If you have
invincibility/slowdown enabled, you immediately get sent back to the
Secret Lab. However, this check is ignored in custom levels, because
custom levels may want to use the Super Gravitron and let players have
invincibility/slowdown while doing so (and there are in fact custom
levels out in the wild that use the Super Gravitron; it was like one of
the first things done when people discovered internal scripting).
No message pops up when the game sends you back to the Secret Lab, but
no message popped up when the Secret Lab menu option was disabled
previously in the first place, so I haven't made anything WORSE, per se.
A nice effect of this is that you can have invincibility/slowdown
enabled and still be able to go to the Secret Lab from the menu. This is
useful if you just want to check your trophies and leave, without having
to go out of your way to disable invincibility/slowdown just to go
inside.
This factors out the slowdown and invincibility conditionals to a
function. This means less copy-pasted code, and it also conveys intent
(that we don't want to allow competitive options if we have either of
these cheats enabled).
This function isn't implemented in the header because then we would have
to include Map.h for map.invincibility, and transitive includes are
evil. Although, map.invincibility ought to be on Game instead (it was
only mapclass due to 2.2-and-previous argument passing), but that's a
bunch of variable reshuffling that can be done later.
They are now factored out to an inline function named incompetitive().
This is so their usage can be changed without having to change each
individual one in every place. This also clarifies the intent of using
these conditionals (they are for when we're in a "competitive" mode).
This fixes a bug where using the fullscreen toggle keybind (Alt+Enter,
Alt+F, or F11) wouldn't update the color of the "resize to nearest" menu
option. The color doesn't functionally change anything - the option
still won't work, and will still have the message telling you that you
need to be in windowed mode when you move your menu selection to it -
but it's an easy inconsistency to fix; just move the menu recreation in
to Screen::toggleFullScreen() itself.
The game dereferences graphics.screenbuffer without checking it first...
it's unlikely to happen, but the least we can to do be safe is to add a
check and assert here.
Pressing Esc to cancel the confirm quit menu didn't play the squeak, in
contrast to pressing ACTION to cancel it, so now it does; pressing Esc
to close the pause menu or pressing ACTION will also now play the
Viridian squeak too.
The config option has been removed. I'm going to implement something
that automatically shows and hides the mouse cursor whenever
appropriate, which is better than a config option.
This reverts only a part of f196fcd896 -
as the original commit author did not do their changes atomically, they
also squashed in a de-duplication within the same commit. So I'm only
reverting the part of the commit that wasn't the de-duplication, which
is simply the changes to the music.fadeout() calls.
This is being (partially) reverted for several reasons:
1. It's not the correct behavior. What this does instead is persist the
track through after you restart the time trial, instead of fading it
out, then restarting it again. This is in contrast to behavior in
2.2, and I see no reason to not keep the same behavior.
2. It's a single-case patch. The time trials are not the only time in
the game a music track could fade out and then be restarted with the
same track - custom levels could do the same thing too. Instead of
fixing only one case, we should strive to fix EVERY case.
The original commit author (trelbutate) also didn't write anything in
the commit description of f196fcd896. What
you should write in the commit description is things like rationale,
analysis, and other good information that would be useful to anyone
looking at your commit to understand why you did what you did. Having no
commit description leaves readers in the dark as to why you did what you
did.
Thus, I don't know why trelbutate went with this solution, or if they
knew that it was only a single-case patching, or if they knew that it
wasn't 2.2 behavior.
By not writing the commit description, they miss a chance for
reflection; speaking from personal experience, I myself have gone back
and improved my commits countless times because I wrote commit
descriptions for every single one of them, and sometimes whenever I
write them, I think to myself "hang on a minute, that doesn't sound
quite right" and end up finding improvements.
If trelbutate wrote a commit description, they might have realized that
it wasn't 2.2 behavior, and gone back and fixed up their commit to be
correct. As it stands, though, they didn't have to think about it in the
first place because they never bothered to write a commit description.
It turns out this entire chunk of code is simply unneeded (and is
actively harmful) since when we're done with the time trial,
quittomenu() gets called, and that removes the previous stack frame
anyway.
I'm guessing that I added this code, then added quittomenu(), then
didn't consider how this code and quittomenu() would mix. But anyways,
this bug is fixed.
Fixes#714.
This adds music and volume sliders to the audio options. To use the
sliders, you navigate to the given option, then press ACTION, and your
selection will be transferred to the slider. Pressing left or right will
move the slider accordingly. Then you can press ACTION to confirm the
volume is what you want and deselect it, or you can press Esc to cancel
the volume change, and it will revert to the previous volume; both
actions will write your settings to disk.
Most of this commit is just adding infrastructure to support having
sliders in menus (without copy-pasting code), which is a totally
completely new user interface that has never been used before in this
game. If we're going to be adding something new, I want to make sure
that it at least is done the RIGHT way.
Closes#706.
Pressing return in gameplay options would send you back to the pause
menu instead of the general options menu, and pressing return in graphic
options would send you back to the pause menu instead of the general
options menu, too. Additionally, pressing Esc in graphic options would
also send you back to the pause menu instead of the general options
menu.
Like I said before, the menu system is still a bit hardcoded in some
places, and these happened because Terry forgot to update them when he
changed the menus around.
Fixes#711.
The in-game menu code is better than it was in 2.2 but still pretty
hardcoded, so to fix this just change each individual case around. This
bug happened because the "options" button was in the place where "quit
to menu" was previously, but Terry forgot to update it when changing all
the options around.
This is an option for speedrunners whose muscle memory is precisely
trained and used to the 1-frame input delay that existed in 2.2 and
below. It is located in Game Options -> Advanced Options, and is off by
default.
To re-add the 1-frame input delay, we simply move the key.Poll() to the
start of the frame, instead of before an input function gets ran -
undoing what #535 did.
There is a frame ordering-sensitive issue here, where toggling
game.inputdelay at the wrong time could cause double-polling. However,
we only toggle it in an input function, which regardless is always
guaranteed to be ran after key.Poll() (it either happened at the start
of the frame or just before the input function got ran), so this is not
an issue. But, in case we ever need to toggle this variable in the
future, we can just use the defer callbacks system to defer the toggle
to the end of the frame - also added by #535.
Added at the request of Habeechee on the VVVVVV speedrunning Discord
server.
Since mainmenu is only ever used in Input.cpp, I might as well make it
clearer by moving it into a static global variable in Input.cpp. (The
same applies to fadetolab/fadetomenu, but I didn't think much about
those at the time... that'll be a refactor for later.)
While I've decoupled fademode from gamemode starting, being faded out on
the title screen results in a black screen and you being unable to make
any input. So we'll need to store the current fademode in a temporary
variable when going to in-game options, then put it back when we return
to the pause menu. Yes, you can turn on glitchrunner mode during the
in-game options, and then immediately return to the pause menu to
instantly go back to the title screen; this is intended.
Due to frame ordering, putting the fademode back needs to be deferred to
the end of the frame to prevent a 1-frame flicker.
It's actually sufficient enough to do this temporary fademode storage to
fix the whole thing, but I also decided to decouple fademode and
gamemode starting just to be sure.
Assuming glitchrunner mode is off, if you open the pause menu while
fully faded-out and then go to Graphic Options or Game Options, then the
'mode' that you selected previously will kick in again and you'll be
suddenly warped back.
So if you previously started a new game in the main game (mode 0, also
the selected mode if you do this from command-line playtesting), and
then open the pause menu and go to in-game options, then you'll suddenly
go back to starting a new game again. If you had started a custom level,
doing this will warp you back to the start of the level again.
The problem is simple - when the title screen is fully faded out, it
calls startgamemode(). So the solution is simple as well - just decouple
the fademode from calling startgamemode(), and use a different variable
to know when to actually call startgamemode().
This makes it easier to add bounds checks to all accesses of
map.explored. Also, all manually-written existing bounds checks have
been removed, because they're going to go into the new getters and
setters.
The getter is mapclass::isexplored() and the setter is
mapclass::setexplored().
The background would change for 1 frame before sending you back to the
pause menu or editor settings. The map.nexttowercolour() call needs to
be deferred until the end of the frame.
game.shouldreturntoeditor was added to fix a frame ordering issue that
was causing a bug where if you started playtesting in a room with a
horizontal/vertical warp background, and exited playtesting in a
different room that also had a horizontal/vertical warp background and
which was different, then the background of the room you exited in would
slowly scroll offscreen, when you re-entered the editor, instead of the
background consisting entirely of the actual background of the room.
Namely, the issue was that the game would render one more frame of
GAMEMODE after graphics.backgrounddrawn got set to false, and re-set it
to true, thus negating the background redraw, so the editor background
would be incorrect.
With defer callbacks, we can now just use a couple lines of code,
instead of having to add an extra kludge variable and putting handling
for it all over the code.
Previously, before the game loop order got fixed, going to the in-game
settings would switch over to the new render function too early, causing
a deltaframe glitch that had to be fixed. But now, the render function
only gets switched when the current gamestate's function list gets
finished executing, so the game won't suddenly switch to titlerender()
in the middle of the ACTION press to the in-game settings screen.
As a consequence, titleupdatetextcol() no longer needs to be exported to
Input.cpp.
This is a small quality-of-life tweak that makes it so if you're in the
middle of editing a level, you don't have to save the level, exit to the
menu, change whatever setting you wanted, re-enter the editor, and type
in the level name, just to change one setting. This is the same as
adding Graphic Options and Game Options to the in-game pause menu,
except for the editor, too.
To do this, I'm reusing Game::returntopausemenu() (because all of its
callers are the same callers for returning to editor settings) and
renamed it to returntoingame(), then added a variable named
ingame_editormode to Game. When we're in the options menus but still in
the editor, BOTH ingame_titlemode and ingame_editormode will be true.
This is a small quality-of-life thing that makes it so you don't have to
move your menu selection all the way over to the "return" button in
order to return to the previous menu. You can just press Escape instead
to return to the previous menu. The previous behavior of pressing Escape
was to bring up the 'confirm quit' menu, or if you were in an options
menu in-game, return to the pause menu.
If you're on the main menu (and thus don't have any previous menu) and
press Escape, the game will instead bring up the 'confirm quit' menu.
For consistency, the "quit game" option on the main menu will also bring
up the 'confirm quit' menu as well, instead of immediately closing the
game.
Pressing the controller button mapped to Escape will also work as well.
The only menus that don't have return buttons are the 'countdown' menus
- so the game will not let you press Escape if there's a menu countdown
happening.
Now that pressing Escape in the 'continue' menu will just bring you back
to the 'play' menu, there's no need to specifically put
map.nexttowercolour() first when canceling the 'confirm quit' menu.
In #553, when Dav999 added error messages to settings menus if the game
was unable to successfully save the changed settings, he seemed to have
forgotten the PPPPPP/MMMMMM toggle option.
However, I can fully blame him for only that miss. The Flip Mode options
were using game.savemystats (which was removed in #591), so if he
searched for all instances of game.savestats()
(game.savestatsandsettings() was only added in #557), he would've missed
the game.savemystats.
Later, when I did #591, I didn't realize that I should've replaced the
ones in the Flip Mode options with game.savestatsandsettings_menu(), so
part of the blame does fall on me.
Anyways, this is fixed now.
If there was absolutely no music playing, and you went to the in-game
options to switch between MMMMMM and PPPPPP, the behavior would be a bit
glitchy.
If you started with PPPPPP, switching once to MMMMMM wouldn't play
anything, but then switching back to PPPPPP would play MMMMMM track 15.
Then switching back to MMMMMM wouldn't do anything, but then switching
back to PPPPPP again would play PPPPPP track 15 - and from there, the
behavior is stable.
If you started with MMMMMM, switching once to PPPPPP would play MMMMMM
track 15. Then switching back to MMMMMM wouldn't do anything, but then
switching back to PPPPPP would play PPPPPP track 15 - and as above, the
behavior is stable after that.
Anyways, the point is, -1 shouldn't be passed to musicclass::play()
unless you want glitchy things. And I'm not patching -1 out of
musicclass::play() itself, because passing negative numbers results in a
useful glitch (that's existed since 2.2) where you can play MMMMMM
tracks while having PPPPPP selected, effectively doubling the amount of
usable music tracks within a custom level; it also seems like the game
does -1 checks elsewhere, so I'm just being consistent with the rest of
the game (although, yes, I am technically single-case patching this).
This bug is technically NOT a regression - the code responsible for it
has been around since the source release.
However, it hasn't been a problem until Graphic Options and Game Options
were added to the pause screen. Since then, if you opened the pause menu
in Flip Mode, pressing up would move to the menu option below, and
pressing down would move to the menu option above. Notably, left and
right still remain the same.
This is because the map screen input code assumes that the menu options
will be flipped around - however, this has never been the case. What
happens instead is that the menu options get flipped around time when in
Flip Mode - flipping what's already flipped - so it ends up the same
again.
(Incidentally enough, the up/down reversing code is present on the title
screen, and is correct - if you happen to set graphics.flipmode to true
on the title screen, the title screen doesn't negate the flipped menu
options, so pressing up SHOULD be treated like pressing down, and vice
versa. However, in 2.3, it's not really possible to set
graphics.flipmode to true on the title screen without using GDB or
modifying the game. In 2.2 and previous, you can just complete the game
in Flip Mode, and the variable won't be reset; 2.3 cleaned up all exit
paths to the menu to make sure everything got reset.)
This isn't a problem when there's only two options, but since 2.3 adds
two more options to the pause screen, it's pretty noticeable.
Anyway, this is fixed by simply removing the branch of the
graphics.flipmode if-else in mapinput(). The 'else' branch is now the
code that gets executed unconditionally. Don't get confused by the diff;
I decided to unindent in the same commit because it's not that many
lines of code.
Since you're now allowed to bring up the map screen during cutscenes,
you've also been able to activate activity zones and teleporter prompts
during cutscenes. This only really affects custom levels; nowhere in the
main game can you overlap with an activity zone while in a cutscene.
To fix this, I've just added a script.running check to Enter keybind
processing.
I was looking through all calls to game.returnmenu(), and I noticed that
the return option in the game pad screen didn't have a
map.nexttowercolour(). I tested it and, yep, returning from there
doesn't update the background color.
So that should be fixed now.
I'm... not sure why this was here? It's absolutely not needed.
I'm guessing maybe at one point during development, there might have
been wanted a special song to be played during the credits, or no song
at all (although the function being niceplay() instead of play() seems
to support the first possibility) - but there's no need for this to be
here.
Now that recreating the same menu keeps currentmenuoption, we can remove
all these superfluous assignments. This means repeating ourselves less;
in case the option numbers change in the future, we won't have to
remember to update these reassignments, too.
ClearSurface() is less verbose than doing it the old way, and also
conveys intent clearer. Plus, some of these FillRect()s had hardcoded
width and height values, whereas ClearSurface() doesn't - meaning this
change also has better future-proofing, in case the widths and heights
of the surfaces involved change in the future.
Apparently in C, if you have `void test();`, it's completely okay to do
`test(2);`. The function will take in the argument, but just discard it
and throw it away. It's like a trash can, and a rude one at that. If you
declare it like `void test(void);`, this is prevented.
This is not a problem in C++ - doing `void test();` and `test(2);` is
guaranteed to result in a compile error (this also means that right now,
at least in all `.cpp` files, nobody is ever calling a void parameter
function with arguments and having their arguments be thrown away).
However, we may not be using C++ in the future, so I just want to lay
down the precedent that if a function takes in no arguments, you must
explicitly declare it as such.
I would've added `-Wstrict-prototypes`, but it produces an annoying
warning message saying it doesn't work in C++ mode if you're compiling
in C++ mode. So it can be added later.
This patch restores some 2.2 behavior, fixing a regression caused by the
refactor of properly using std::vectors.
In 2.2, the game allocated 200 items in obj.entities, but used a system
where each entity had an `active` attribute to signify if the entity
actually existed or not. When dealing with entities, you would have to
check this `active` flag, or else you'd be dealing with an entity that
didn't actually exist. (By the way, what I'm saying applies to blocks
and obj.blocks as well, except for some small differing details like the
game allocating 500 block slots versus obj.entities's 200.)
As a consequence, the game had to use a separate tracking variable,
obj.nentity, because obj.entities.size() would just report 200, instead
of the actual amount of entities. Needless to say, having to check for
`active` and use `obj.nentity` is a bit error-prone, and it's messier
than simply using the std::vector the way it was intended. Also, this
resulted in a hard limit of 200 entities, which custom level makers ran
into surprisingly quite often.
2.3 comes along, and removes the whole system. Now, std::vectors are
properly being used, and obj.entities.size() reports the actual number
of entities in the vector; you no longer have to check for `active` when
dealing with entities of any sort.
But there was one previous behavior of 2.2 that this system kind of
forgets about - namely, the ability to have holes in between entities.
You see, when an entity got disabled in 2.2 (which just meant turning
its `active` off), the indices of all other entities stayed the same;
the indice of the entity that got disabled stays there as a hole in the
array. But when an entity gets removed in 2.3 (previous to this patch),
the indices of every entity afterwards in the array get shifted down by
one. std::vector isn't really meant to be able to contain holes.
Do the indices of entities and blocks matter? Yes; they determine the
order in which entities and blocks get evaluated (the highest indice
gets evaluated first), and I had to fix some block evaluation order
stuff in previous PRs.
And in the case of entities, they matter hugely when using the
recently-discovered Arbitrary Entity Manipulation glitch (where crewmate
script commands are used on arbitrary entities by setting the `i`
attribute of `scriptclass` and passing invalid crewmate identifiers to
the commands). If you use Arbitrary Entity Manipulation after destroying
some entities, there is a chance that your script won't work between 2.2
and 2.3.
The indices also still determine the rendering order of entities
(highest indice gets drawn first, which means lowest indice gets drawn
in front of other entities). As an example: let's say we have the player
at 0, a gravity line at 1, and a checkpoint at 2; then we destroy the
gravity line and create a crewmate (let's do Violet).
If we're able to have holes, then after removing the gravity line, none
of the other indices shift. Then Violet will be created at indice 1, and
will be drawn in front of the checkpoint.
But if we can't have holes, then removing the gravity line results in
the indice of the checkpoint shifting down to indice 1. Then Violet is
created at indice 2, and gets drawn behind the checkpoint! This is a
clear illustration of changing the behavior that existed in 2.2.
However, I also don't want to go back to the `active` system of having
to check an attribute before operating on an entity. So... what do we
do to restore the holes?
Well, we don't need to have an `active` attribute, or modify any
existing code that operates on entities. Instead, we can just set the
attributes of the entities so that they naturally get ignored by
everything that comes into contact with it. For entities, we set their
invis to true, and their size, type, and rule to -1 (the game never uses
a size, type, or rule of -1 anywhere); for blocks, we set their type to
-1, and their width and height to 0.
obj.entities.size() will no longer necessarily equal the amount of
entities in the room; rather, it will be the amount of entity SLOTS that
have been allocated. But nothing that uses obj.entities.size() needs to
actually know the amount of entities; it's mostly used for iterating
over every entity in the vector.
Excess entity slots get cleaned up upon every call of
mapclass::gotoroom(), which will now deallocate entity slots starting
from the end until it hits a player, at which point it will switch to
disabling entity slots instead of removing them entirely.
The entclass::clear() and blockclass::clear() functions have been
restored because we need to call their initialization functions when
reusing a block/entity slot; it's possible to create an entity with an
invalid type number (it creates a glitchy Viridian), and without calling
the initialization function again, it would simply not create anything.
After this patch is applied, entity and block indices will be restored
to how they behaved in 2.2.
There are multiple different exit paths to the main menu. In 2.2, they
all had a bunch of copy-pasted code. In 2.3 currently, most of them use
game.quittomenu(), but there are some stragglers that still use
hand-copied code.
This is a bit of a problem, because all exit paths should consistently
have FILESYSTEM_unmountassets(), as part of the 2.3 feature of per-level
custom assets. Furthermore, most (but not all) of the paths call
script.hardreset() too, and some of the stragglers don't. So there could
be something persisting through to the title screen (like a really long
flash/shake timer) that could only persist if exiting to the title
screen through those paths.
But, actually, it seems like there's a good reason for some of those to
not call script.hardreset() - namely, dying or completing No Death Mode
and completing a Time Trial presents some information onscreen that
would get reset by script.hardreset(), so I'll fix that in a later
commit.
So what I've done for this commit is found every exit path that didn't
already use game.quittomenu(), and made them use game.quittomenu(). As
well, some of them had special handling that existed on top of them
already having a corresponding entry in game.quittomenu() (but the path
would take the special handling because it never did game.quittomenu()),
so I removed that special handling as well (e.g. exiting from a custom
level used returntomenu(Menu::levellist) when quittomenu() already had
that same returntomenu()).
The menu that exiting from the level editor returns to is now handled in
game.quittomenu() as well, where the map.custommode branch now also
checks for map.custommodeforreal. Unfortunately, it seems like entering
the level editor doesn't properly initialize map.custommode, so entering
the level editor now initializes map.custommode, too.
I've also taken the music.play(6) out of game.quittomenu(), because not
all exit paths immediately play Presenting VVVVVV, so all exit paths
that DO immediately play Presenting VVVVVV now have music.play(6)
special-cased for them, which is fine enough for me.
Here is the list of all exit paths to the menu:
- Exiting through the pause menu (without glitchrunner mode)
- Exiting through the pause menu (with glitchrunner mode)
- Completing a custom level
- Completing a Time Trial
- Dying in No Death Mode
- Completing No Death Mode
- Completing an Intermission replay
- Exiting from the level editor
- Completing the main game
This variable seems to have been intended to make sure
game.savestatsandsettings() was called at the end of the frame, or make
sure that it didn't get called more than once per frame. I don't see any
frame ordering-related reason why it needs to be called specifically at
the end of the frame (the function doesn't modify any state), so it's
more plausible that it was added to make sure it didn't get called more
than one per frame.
However, upon further analysis, none of the code paths where
game.savemystats is used ever calls or sets game.savemystats more than
once, and a majority of the code directly calls
game.savestatsandsettings() anyway, so there's no reason for this
variable to exist. If we ever need to make sure it doesn't get called
more than once, and there's no way to change the code paths around to
prevent it otherwise, we can use the defer callbacks system that I added
to #535, when it gets merged.
This patch cleans up unnecessary exports from header files (there were
only a few), as well as adds the static keyword to all symbols that
aren't exported and are specific to a file. This helps the linker out in
not doing any unnecessary work, speeding it up and avoiding silent
symbol conflicts (otherwise two symbols with the same name (and
type/signature in C++) would quietly resolve as okay by the linker).
This fixes a bug where if you completed a custom level during
command-line playtesting, when returning to the title screen, the
background would be red and the text would be white.
This is because playtesting skips over the code path of pressing ACTION
to start the game and advance to the title screen, and the code path of
that ACTION press specifically initializes the title screen colors to
cyan.
This is also caused by the fact that completing a custom level doesn't
call map.nexttowercolour(), but my guess is that the intent there was
that the player would select a custom level, complete it, and return to
the title screen on the same screen with the same colors, so I decided
not to add a map.nexttowercolour() there.
Instead, I've moved the cyan color initialization to main(), so that it
is always executed no matter what, and doesn't require you to take a
specific code path to do it.
This reverts commit 48313169b6, "Don't
fade music out when returning to the menu if it's Presenting VVVVVV".
This commit is being reverted because it is only a single-case patch -
that is, it fixes only a single symptom of the bug, and not its
underlying cause.
This prevents issues when calling std::abs with a float on some older
compilers. While it would normally be promoted to an int, std::abs is
special due to being overloaded despite being a C function. This can
cause errors due to the compiler being unable to find a float overload.
SDL_abs doesn't have this problem, since it's a normal C function.
When gamemode(teleporter) gets run in a script, it brings up a read-only
version of the teleporter screen, intended only for displaying rooms on
the minimap.
However, ever since 2.3 allowed bringing up the map screen during
cutscenes (in order to prevent softlocks), bringing up the map screen
during this mode would (1) do an unnecessary animation of suddenly
switching back to the game and bringing up the menu screen again (even
though the menu screen has already been brought up), and (2) would let
you close the menu entirely and go back to GAMEMODE, thus
unintentionally closing the teleporter screen and kind of ruining the
cutscene.
To fix this, when you bring up the map screen, it will instead instantly
transition to the map screen. And when you bring it down, it will also
instantly transition back to the teleporter screen.
But that's not all. The previous behavior was actually kind of a nice
failsafe, in that if you somehow got stuck in a state where a script ran
gamemode(teleporter), but stopped running before it could take you out
of that mode by running gamemode(game), then you could return to
GAMEMODE yourself by bringing up the map screen and then bringing it
back down. So I've made sure to keep that failsafe behavior, only as
long as there isn't a script running.
When bringing up the map screen, the game does a small menu animation
where the menu comes in from the bottom. The code to calculate the menu
offset is copy-pasted everywhere, so I thought I'd de-duplicate it to
make my life easier when working with it. I also included the
game.gamestate assignment in the de-duplicated function, so it would be
easier for a future bugfix.
At the same time, I'm also removing all the BlitSurfaceStandard()s that
copied menubuffer to backBuffer. The red flag is that this blit happened
for every single entry point to MAPMODE and TELEPORTERMODE, except for
the script command gamemode(teleporter). Pressing Enter to bring up the
map screen, pressing Enter to quit the Super Gravitron, pressing Esc to
bring up the pause screen, and pressing Enter to bring up the teleporter
screen all do this blit, so if this blit was there to fix a bug, then
there's a bug with using the script command gamemode(teleporter)... but,
as far as I can tell, there isn't.
That's because the blit basically does nothing. All the blit does is
copy menubuffer onto backBuffer. Then the next thing that happens is
that either maprender() or teleporterrender() will be called, and the
first thing that those functions will always do is fill backBuffer with
solid black, completely overriding the previous blit. So that's why
removing this blit won't have any effect, and it can be safely removed
for code clarity.
While working on #535, I noticed this bug.
When going to Graphic Options or Game Options from the pause menu,
kludge_ingametemp was intended to save the current menu stack frame
BEFORE either of those menus got created. However, it was actually
assigned afterwards, meaning kludge_ingametemp would always be either
Menu::graphicoptions or Menu::options.
This meant that the returntomenu() in returntopausemenu() would always
attempt to return to the current in-game menu, and seeing as it's the
same menu, would re-create the menu, instead of returning to the
previous menu before it.
This patch also fixes a potential source of a trivial memory leak, if
someone were to keep entering and exiting Graphic Options or Game
Options from the pause menu. It would keep piling up duplicate Graphic
Options or Game Options stack frames, which would never get removed.
However, they do get removed when you exit to the menu properly, by
returntomenu() again, so this doesn't seem like that serious of an
issue, but it's still good to fix.
In order to be able to fix the bug #556, I'm planning on adding
ScreenSettings* to the settings.vvv write function. However, that
entails adding another argument to Game::savesettings(), which is going
to be really messy given the default argument of Game::savestats().
That, combined with the fact that the code comment at the site of the
implementation of Game::savestats() being wrong (!!!), leads me to
believe that using default function arguments here isn't worth it.
Instead, what I've done is made it so callers are explicit about whether
or not they're calling savestats(), savesettings(), or both at the same
time. If they are calling both at the same time, then they will be using
a new function named savestatsandsettings().
In short, these are the interface changes:
* bool Game::savestats(bool) has been removed
* bool Game::savestatsandsettings() has been added
* void Game::savestats_menu() has been renamed to
void Game::savestatsandsettings_menu()
* All previous callers of bool Game::savestats() are now using bool
Game::savestatsandsettings()
* The one caller of bool Game::savestats(bool) is now using bool
Game::savestats()
Changing settings would most of the time attempt to save unlock.vvv and
now also settings.vvv, but there would be no feedback whether the files
have been saved successfully or not. Now, if saving fails when changing
settings in the menu, a warning message will be shown. The setting will
still be applied of course, but the user will be informed it couldn't
be saved. This message can be silenced until the game is restarted,
because I can imagine this could get very annoying when someone already
knows their settings aren't writeable.
Also, some options didn't even save settings in the first place. These
are turning off invincibility, and by coincidence precisely all the
options in the advanced options menu. I made sure these options now do
so.
As part of fixing #464, I'll need to move these pieces of code around
easily. In #220 I just kind of shoved them awkwardly in whatever
fixed function would be last called in the gamestate loop, which I
shouldn't have done as I've now had to make formal fixed-render
functions anyway. Because these fixed functions need to be called
directly before a render function, and I'm fixing the order to put
render functions in their proper place, so I need to be able to move
these around easily, and making them function calls instead of inlined
makes them easier to manipulate.
PR #468 made it so you can use the menus while in a cutscene, in order
to counteract softlocks. However, this has resulted in more
unintentional behavior:
- `gamemode(teleporter)` breaks when opening the ENTER menu (Misa
mentioned this)
- The player can now interrupt shakes and walks, and have their timers
run out before resuming the cutscene
- After completing the game, the player can warp to the ship while a
dialogue is active, and prevent themselves from advancing text (plus
it's always rude to just teleport away while someone's talking)
- The player can peek at the map before hidecoordinates is run, and can
also peek at what the game does with missing/rescued crewmates during
cutscenes
This commit fixes the latter two issues. While a script is running,
only the SAVE tab is now available. Therefore the player can still get
themselves out of softlocks as intended, but they do things like
looking at the map or teleporting away during a cutscene.
It wasn't a direct duplicate of key.sensitivity, but it was still
basically the same thing. Although to be fair, at least the case-switch
conversion didn't get duplicated everywhere unlike game.slowdown.
So now key.sensitivity functions the same as game.controllerSensitivity,
and it only gets converted to its actual value whenever a joystick input
happens in key.Poll(), unlike previously where it got converted every
single frame on the title screen (there was even a comment that said
"TODO bit wasteful doing this every poll").
game.gameframerate seems to exist for converting the value of
game.slowdown into an actual timestep value, when really the timestep
value should just use game.slowdown directly with a fast lookup table.
Otherwise, there's a bunch of duplicated game.slowdown case-switches
everywhere, which adds up to a large, annoying pile should the values be
changed in the future. But now the duplicate variable has been removed,
and with it, all the copy-pasted case-switches.
Also, the game speed text rendering in Menu::accessibility and
Menu::setslowdown has been factored out to a function and de-duplicated
as well.
There were some duplicate Screen configuration variables that were on
Game, when there didn't need to be.
- game.fullScreenEffect_badSignal is a duplicate of
graphics.screenbuffer->badSignalEffect
- game.fullscreen is a duplicate of !graphics.screenbuffer->isWindowed
- game.stretchMode is a duplicate of graphics.screenbuffer->stretchMode
- game.useLinearFilter is a duplicate of
graphics.screenbuffer->isFiltered
These duplicate variables have been removed now.
I put indentation when handling the ScreenSettings struct in main() so
the local doesn't live for the entirety of main() (which is the entirety
of the program).
Here's what causes #401: After the fade to menu delay ticks down to 0,
the game calls game.quittomenu(), but the rest of mapinput() still
executes. This means that the block that detects your ACTION press gets
executed, because there's a check that fadetomenudelay is less than or
equal to 0, and, well, it is.
So if you've pressed ACTION on the exact frame that it counts down to 0,
then the game detects your ACTION press, then processes it accordingly,
and then sets the fadetomenudelay, which means it'll get reactivated the
next time you open the map screen. But at this point, you get sent to
TITLEMODE, because game.quittomenu() set game.gamestate accordingly.
(This is why resetting game.fadetomenu or game.fadetomenudelay in
game.quittomenu() or script.hardreset() won't fix this bug.)
The solution here is to add a game.fadetomenu check to the ACTION press
processing.
Same-frame state transition logic is hard... actually, any sort of thing
where two things happen on the same frame is really annoying.
This also applies to fadetolab and fadetolabdelay, too.
Fixes#401.
The game previously did this dumb thing where it lumped in all its
settings with its file that tracked your records and unlocks,
`unlock.vvv`. It wasn't really an issue, until 2.3 came along and added
a few settings, suddenly making a problem where 2.3 settings would be
reset by chance if you decided to touch 2.2.
The solution to this is to move all settings to a new file,
`settings.vvv`. However, for compatibility with 2.2, settings will still
be written to `unlock.vvv`.
The game will prioritize reading from `settings.vvv` instead of
`unlock.vvv`, so if there's a setting that's missing from `unlock.vvv`,
no worries there. But if `settings.vvv` is missing, then it'll read
settings from `unlock.vvv`. As well, if `unlock.vvv` is missing, then
`settings.vvv` will be read from instead (I explicitly tested for this,
and found that I had to write special code to handle this case,
otherwise the game would overwrite the existing `settings.vvv` before
reading from it; kids, make sure to always test your code!).
Closes#373 fully.
