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.
Now that tower, title, and horizontal/veritcal warp backgrounds all use
separate buffers, there's no longer any need to temporarily store
variables as a workaround for the buffers stepping on each other.
With the previous commit in place, we can now simply move some usages of
the previous towerbg to use a separate object instead. That way, we
don't have to mess with a monolithic state, or some better way to phrase
what I just said, and we instead have two separate objects that can
coexist side-by-side.
Previously, the tower background was controlled by a disparate set of
attributes on Graphics and mapclass, and wasn't really encapsulated. (If
that's what that word means, I don't particularly care about
object-oriented lingo.) But now, all relevant things that a tower
background has has been put into a TowerBG struct, so it will be easy to
make multiple copies without having to duplicate the code that handles
it.
It's better to do INBOUNDS_VEC(i, obj.entities) instead of 'i > -1'.
'i > -1' is used in cases like obj.getplayer(), which COULD return a
sentinel value of -1 and so correct code will have to check that value.
However, I am now of the opinion that INBOUNDS_VEC() should be used and
isn't unnecessary.
Consider the case of the face() script command: it's not enough to check
i > -1, you should read the routine carefully. Because if you look
closely, you'll see that it's not guaranteed that 'i' will be initialized
at all in that command. Indeed, if you call face() with invalid
arguments, it won't be. And so, 'i' could be something like 215, and
that would index out-of-bounds, and that wouldn't be good. Therefore,
it's better to have the full bounds check instead of checking only one
bounds. Many commands are like this, after some searching I can also
name position(), changemood(), changetile(), changegravity(), etc.
It also makes the code more explicit. Now you don't have to wonder what
-1 means or why it's being checked, you can just read the 'INBOUNDS' and
go "oh, that checks if it's actually inbounds or not".
There's not really any good reason to prevent this action during a fade
animation. That just makes the fade timer one more potential contributor
to a softlock.
I'm leaving the fademode conditional on the Time Trial quick restart,
though - removing it would mean being able to quick restart during a
fade-in, and thus being able to spam Enter over and over to keep
re-starting the fade animation, which looks goofy.
The hooks to bring up the map screen, pause screen, quit from Super
Gravitron, restart Time Trial, and commit suicide have now been hoisted
out of the for-loop that checked for a player entity. None of these
actions require a player entity, and there's no good reason to take away
your control from any of these actions, especially being able to quit to
the menu. The only actions inside the for-loop now are activating a
terminal and activating a teleporter, both of which require a player
entity to be standing in front of a terminal or teleporter, and both of
which have good reasons to be temporarily disabled.
There's not really any need for it to be there. It gets called when the
Time Trial restarts, as restarting the Time Trial calls
script.startgamemode(), which calls script.hardreset() anyway.
Furthermore, since script.hardreset() is removed, we can also remove two
lines that are meant to work around the fact that everything gets reset,
which is now no longer the case.
Fixes#367.
This fixes the bug where in glitchrunner mode, quitting to the menu
would always put you back at the play menu on the first option, instead
of the menu you entered the game from.
The problem is the script.hardreset() that gets called before the game
actually quits to the menu, so when Game::quittomenu() gets called to
quit to the menu, all the variables that keep track of whether you're in
a certain gamemode, such as game.insecretlab and map.custommode, all get
prematurely reset before that function can read them and put you back to
the correct menu.
The solution here is to simply reset only what's needed when quitting to
the menu. Specifically, in order for credits warp to work,
script.running needs to be set to false and all the text boxes need to
be removed. Text boxes need to be gone so the "- Press ACTION to advance
text -" prompt will stay up without a text box, enabling the player to
increment the gamestate at will by pressing ACTION, and the script needs
to stop running so further text boxes don't spawn in.
Fixes#389.
