This overhauls scriptclass::gamemode massively.
The first change is that it now uses an enum, and enforces using that
enum via using its type instead of an int. This is because whenever
you're reading any calls to startgamemode, you have no idea what magic
number actually corresponds to what unless you read startgamemode
itself. And when you do read it, not every case is commented adequately,
so you'd have to do more work to figure out what each case is. With the
enum, it's obvious and self-evident, and that also removes the need for
all the comments in the function too. Some math is still done on mode
variables (to simplify time trial code), but it's okay, we can just cast
between int and the enum as needed.
The second is that common code is now de-duplicated. There was a lot of
code that every case does, such as calling hardreset, setting Flip Mode,
resetting the player, calling gotoroom and so on.
Now some code may be duplicated between cases, so I've tried to group up
similar cases where possible (most notable example is grouping up the
main game and No Death Mode cases together). But some code still might
be duplicated in the end. Which is okay - I could've tried to
de-duplicate it further but that just results in logic relevant to a
specific case that's located far from the actual case itself. It's much
better to leave things like setting fademode or loading scripts in the
case itself.
This also fixes a bug since 2.3 where playing No Death Mode (and never
opening and closing the options menu) and beating it would also give you
the Flip Mode trophy, since turning on the flag to invalidate Flip Mode
in startgamemode only happened for the main game cases and in previous
versions the game relied upon this flag being set when using a
teleporter for some reason (which I removed in 2.3). Now instead of
specifying it per case, I just do a !map.custommode check instead so it
covers every single case at once.
This fixes a regression where the game ignored the amount of frames you
held down a direction if you released the direction during death.
Previously, the game only checked the amount of frames you held down a
direction if you were able to control the player. If you weren't able to
control the player (e.g. during the death animation), then the number of
frames it counted didn't change. This also meant that if you were
holding a direction before you died, but released it during death, the
game wouldn't zero out the number of frames you held it.
This behavior was useful because it meant you could keep the
deceleration momentum that you normally get by holding a direction for 5
frames just by holding a direction for less than 5 frames after dying,
if you had the rest of the hold frames before you died. This behavior is
what's used in https://tasvideos.org/7575S at around frame 7200.
Unfortunately, #609 made it so that the direction hold processing
happened even if the player didn't have control, meaning that it would
zero the hold frames during the death animation in the TAS, thus
desyncing it when it performed the maneuver it relied on the extra
momentum for after Viridian respawns.
The solution here is to just add the check back in again.
Fixes#887.
This removes the magic numbers previously used for controlling the fade
mode, which are really not readable at all unless you already know what
they mean.
0: FADE_NONE
1: FADE_FULLY_BLACK
2: FADE_START_FADEOUT
3: FADE_FADING_OUT
4: FADE_START_FADEIN
5: FADE_FADING_IN
There is also the macro FADEMODE_IS_FADING, which indicates when the
intention is to only check if the game is fading right now, which wasn't
clearly conveyed previously.
I also took the opportunity to clean up the style of any lines I
touched. This included rewriting if-else chains into case-switches,
turning one-liner if-then statements into proper blocks, fixing up
comments, and even commenting the `fademode == FADE_NONE` on the tower
spike checks (which, it was previously undocumented why that check was
there, but I think I know why it's there).
As for type safety, we already get some by transforming the variable
types into the enum. Assignment is prohibited without a cast. But,
apparently, comparison is perfectly legal and won't even give so much as
a warning. To work around this and make absolutely sure I made all
existing comparisons now use the enum, I temporarily changed it to be an
`enum class`, which is a C++11 feature that makes it so all comparisons
are illegal. Unfortunately, it scopes them in a namespace with the same
name as a class, so I had to temporarily define macros to make sure my
existing code worked. I also had to temporarily up the standard in
CMakeLists.txt to get it to compile. But after all that was done, I
found the rest of the places where a comparison to an integer was used,
and fixed them.
This is mainly to make sure the game is definitely set to fullscreen in
Big Picture and on the Steam Deck, and to also remove windowed options
that wouldn't make sense if you're not on a desktop (toggling
fullscreen, resize to nearest). Those options would also be removed on
console and mobile too.
There's a bit of an annoying bug where if you launch the game in forced
fullscreen mode, but then exit and relaunch in normal mode, your game
will have fullscreen window sizes but it won't be fullscreen. This is
because forced fullscreen mode tries to preserve your non-forced
fullscreen setting, but due to the way window sizes are stored and
queried, it can't preserve the non-forced window size. This is a bit
difficult to work around, so I'm just putting in a FIXME here because we
can fix it later and I'd rather have a slightly buggy forced fullscreen
mode than not have one at all.
Closes#849.
I know earlier I removed the gameScreen extern in favor of using
screenbuffer, but that was only to be consistent. After further
consideration, I have found that it's actually really stupid.
There's no reason to be accessing it through screenbuffer, and it's
probably an artifact of 2.0-2.2 passing stack-allocated otherwise-global
classes everywhere through function arguments. Also, it leads to stupid
bugs where screenbuffer could potentially be NULL, which has already
resulted in various annoying crashes in the past. Although those could
be fixed by simply initializing screenbuffer at the very top of main(),
but, why not just scrap the whole thing anyway?
So that's what I'm doing.
As a nice side effect, I've removed the transitive include of Screen.h
from Graphics.h. This could've been done already since it only includes
it for the pointer anyway, but it's still good to do it now.
It's been long overdue that this variable be named properly. 2.2 added
integer scaling mode (thanks Ethan), 2.3 renamed it to scaling mode. Now
2.4 will properly call it what it is so people won't be confused by it.
The ScreenSettings struct member is renamed from stretch to scalingMode
along with the Screen class member being renamed, as well as the
toggleStretchMode function being renamed to toggleScalingMode as well.
Unfortunately, due to compatibility, we can't change the <stretch> XML
tag.
The reason why the wall stuck flipping behavior happened in the first
place was because the code went like this:
if (jumppressed)
{
if (onground && gravitycontrol == 0)
{
gravitycontrol = 1;
}
if (onroof && gravitycontrol == 1)
{
gravitycontrol = 0;
}
}
Basically, if you were both on ground and on a roof (i.e. stuck in a
wall), you would flip, but then due to code order and the fact that the
statement is not connected to the previous one, you would immediately
unflip afterwards. But if you were already flipped then the only path
that can be taken is to unflip you, since it's the statement that
appears last.
52fceb3f69 replaces the onground/onroof
conditionals with any_onground/any_onroof, so any player entity would
allow you to flip. But otherwise the code is the same. So is that the
problem?
No; tracing it through with GDB reveals that when you flip,
gravitycontrol is being set to 1, but never being set to 0. And it turns
out that's because any_onroof is not getting set. And that happens
because of another thing that 52fceb3f69
did - which was to set any_onground/any_onroof to true if indeed any
player entity was on ground or on a roof.
Unfortunately, the way Leo did it was to make the two statements
mutually exclusive - an 'if'-'else if' instead of two separate
statements. So a single entity could not mark both any_onground and
any_onroof as true (and the majority of the time, you will be a single
entity).
Thus, the solution is to just drop that 'else'.
Fixes#855.
The game will now assert if the main menu is created while
ingame_titlemode is true, or if we attempt to load into a mode while
it's true. And if assertions are disabled then it just stops doing it
anyway.
I don't think there's any way to get a glitched ingame_titlemode again,
ever since I removed save data deletion taking you back to the main
menu. But I've had enough bugs with the fact that we more-or-less use
the same state for main menu options and in-game options, and that
glitched ingame_titlemode bug DID just happen, so I'm taking
precautions.
The next commit will add logic that more-or-less quits the whole block
if ingame_titlemode, and instead of adding another layer of indentation
I will just pull this into its own function so we can use a return
statement.
Going back to the main menu allowed for glitchiness to occur if you
deleted your save data while in in-game options. This meant you could
then load back in to the game, and then quit to the menu, then open the
options and then jump back in-game, exploring the state of the game
after hardreset() had been called on it. Which is: pretty glitchy.
For example, this meant having your room coordinates be 0,0 (which is
different from 100,100, which is the actual 0,0, thanks for the
100-indexing Terry), which caused some of the room transitions to be
disabled because room transitions were disabled if the
game.door_up/down/left/right variables were -2 or less, and they were
computed based on room coordinates, which meant some of them went
negative if you were 0,0 and not 100,100. At least this was the case
until I removed those variables for, at best, doing nothing, and at
worst, being actively harmful.
Anyways, so deleting your save data now just takes you back to the
previous menu, much like deleting custom level data does. I don't know
why deleting save data put you back on the main menu in the first place.
It's not like the options menu needed to be reloaded or anything. I
checked and this was the behavior in 2.0 as well, so it was probably
added for a dumb reason.
I considered prohibiting data deletion if you were ingame_titlemode, but
as of the moment it seems to be okay (if albeit weird, e.g. returning to
menu while in Secret Lab doesn't place your cursor on the "play"
button), and I can always add such a prohibition later if it was really
causing problems. Can't think of anything bad off of the top of my head,
though.
Btw thanks to Elomavi for discovering that you could do this glitch.
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.
