Ever since VVVVVV was initially ported to C++ in 2.0, it has used surfaces from SDL. The downside is, that's all software rendering. This commit moves most things off of surfaces, and all into GPU, by using textures and SDL_Renderer.
Pixel-perfect collision has been kept by keeping a copy of sprites as surfaces. There's plans for pixel-perfect collision to use masks instead of reading pixel data directly, but that's out of scope for this commit.
- `graphics.reloadresources()` is now called later in `main`, because textures cannot be created without a renderer.
- This commit also removes a bunch of surface functions which are no longer needed.
- This also recaches target textures in certain places for d3d9.
- graphics.images was converted to a fixed-size array.
- fillbox and fillboxabs use SDL_RenderDrawRect instead of drawing an outline using four filled rectangles
- Update my name in the credits
This adds loc::gettext for all "Press {button} to explode" and friends,
and also changes the interact_prompt function in Render.cpp to expect
{button} instead of %s.

I have no idea why they were floats in the first place. They are
coordinates, and coordinates are integer positions in this game. They
get converted to float only to be explicitly `static_cast`ed back to
ints in `testwallsy`.
This variable passes along the rule of the entity, which is an int. No
idea why it was converted to a float. Thankfully this is only used for
an unused block type, so it doesn't really matter.
There's always been a bit of an inconsistency in the game where enabling
invincibility would make spikes so solid that enemies and moving
platforms would treat spikes as solid and bounces off of them.
This fixes that by adding an `invincible` parameter to collision
functions, so the functions will only treat spikes as solid if that
parameter is true, and the parameter passed will only be true if it's
called for an entity that is a humanoid and invincibility mode is
enabled.
Also, for clarity, `spikecollide` is renamed to `towerspikecollide`
because it's only used for tower spikes. And as a small optimization,
`checktowerspikes` returns early if invincibility mode is enabled.
As reported by Dav999, Victoria and Vermilion's trophy colors are
swapped again in 2.4. He points to
37b7615b71, the commit where I fixed the
color masks of every single surface to always be RGB or RGBA.
It sounded plausible to me, because it did have to do with colors, after
all. However, it didn't make sense to me, because I was like, I didn't
touch the trophy colors at all after I originally fixed them.
After I ruled out the RGBf() function as a confounder, I decided to see
whether intentionally reversing the color order in RGBf() to be BGR
would do anything, and to my surprise it actually swapped the colors
back around and it didn't actually look bad.
And then I realized: Swapping the trophy colors between RGB and BGR
ordering results in similar colors that still look good, but are simply
wrong, but not so wrong that they take on a color that no crewmate uses,
so it'd appear as if the crewmates were swapped, when in reality the
only thing that was swapped was actually the color order of the colors.
Trying to fix this by swapping the colors again, I actively confused
colors 33 and 35 (Vermilion and Victoria) with colors 32 and 34
(Vitellary and Viridian), so I was confused when Vermilion and Victoria
weren't swapping. Then as a debugging step, I only changed 34 to 32
without swapping 32 as well, and then finally noticed that I was
swapping Vitellary and Viridian, because there were now two Vitellarys.
And then I was reminded that Vitellary and Viridian were also wrongly
swapped since 2.0 as well.
And so then I finally realized: The original comments accompanying the
colors were correct after all. The only problem was that they were fed
into a function, RGBf(), that read the colors backwards, because the
codebase habitually changed the color order on a whim and it was really
hard to reason out which color order should be used at a given time, so
it ended up reading RGB colors as BGR, while it looked like it was
passing them through as-is.
So what happened was that in the first place, RGBf() was swapping RGB to
BGR. Then I came and swapped Vermilion and Victoria, and Vitellary and
Viridian around. Then later I fixed all the color masks, so RGBf()
stopped swapping RGB and BGR around. But then this ended up swapping the
colors of Vermilion and Victoria, and Vitellary and Viridian once again!
Therefore, swapping Vermilion and Victoria, and Vitellary and Viridian
was incorrect. Or at least, not the fix to the root cause. The root
cause would be to swap the colors in RGBf(), but this would be sort of
confusing to reason about - at least if I didn't bother to just type the
RGB values into an image editor. But that doesn't fix the real issue,
which is that the game kept swapping RGB and BGR around in every corner
of the codebase.
I further confirmed that there was no more RGB or BGR swapping by
deleting the plus-one-divide-by-three transformation in RGBf() and
seeing if the colors looked okay. Now with the colors being brighter, I
could see that passing it straight through looked fine, but
intentionally reversing it to be BGR resulted in colors that at a
distance looked okay, but were either washed out or too bright. At least
finally I could use my 8 years of playing this game for something.
So in conclusion, actually, 37b7615b71
("Fix surface color masks") was the real fix, and
d271907f8c ("Fix Secret Lab Time Trial
trophies having wrong colors") was the real regression. It's just that
the regression came first, but it wasn't really a regression until I did
the other fix, so the fix isn't the regression, the regression is...
this is hurting my brain. Or the real regression was the friends we made
along the way, or something like that.
This is the most trivial bug ever caused by the technical debt of those
god-awful reversed color masks.

This reverts commit d271907f8c.
Fixes#862.
* Add `setactivityposition(x,y)`, add new textbox color `transparent`
This commit adds a new internal command as a part of the visual activity zone changes I've been making.
This one allows the user to reposition the activity zone to anywhere on the screen.
In addition, this commit adds the textbox color `transparent`, which just sets r, g and b to 0.
rgb(0, 0, 0) normally creates the color black, however in VVVVVV textboxes, it makes the background
of them invisible, and makes the text the off-white color which the game uses elsewhere.
* add new variables to hardreset
* Fix unwanted text centering; offset position by 16, 4
It makes sense for `setactivityposition(0, 0)` to place the activity zone in the default position,
so the x has been offset by 16, and the y has been offset by 4.
Text was being automatically centered, meaning any activity zone which wasn't centered had misplaced text.
This has been fixed by calculating the center manually, and offsetting it by the passed value.
Believe it or not, there are still some remnants of the ActionScript
coding standards in the codebase! And one of them sometimes pops up
whenever an integer division happens.
As it so happens, it seems like division in ActionScript automatically
produces a decimal number. So to prevent that, the game sometimes
subtracts off the remainder of the number to be divided before
performing the division on it.
Thus, we get statements that look like
(a - (a % b)) / b
And probably more parentheses surrounding it too, since it would be
copy-pasted into yet another larger expression, because of course it
would.
`(a % b)` here is subtracting the remainder of `a` divided by `b`, using
the modulo operator, before it gets divided by `b`. Thus, the number
will always be divisible by `b`, so dividing it will mathematically not
produce a decimal number.
Needless to say, this is unnecessary, and very unreadable. In fact, when
I saw these for the first time, I thought they were overcomplicated
_modulos_, _not_ integer division! In C and C++, dividing an integer by
an integer will always result in an integer, so there's no need to do
all this runaround just to divide two integers.
To find all of these, I used the command
rg --pcre2 '(.+?).+?-.+?(?=\1).+?%.+?([\d]+?).+?\/.+?(?=\2)'
which basically matches expressions of the form 'a - a % b / b', where
'a' and 'b' are identical and there could be any characters in the
spaces.
2.3 introduced a regression with destroy(platforms). The problem was
that isplatform wasn't being set to false when the entity got disabled,
so if the platform was moving, it would keep moving until it hit a wall,
instead of stopping immediately.
There's no reason it needs to be an std::string here.
Although, realistically, we should be using an enum instead of
string-typing, but, eh, that can be fixed later.
That's what edlevelclass is... so that's what it should be named. (Also
removes that "ed", too, making this less coupled to the in-game editor.)
Unfortunately, for compatibility reasons, the name of the XML element
will still remain the same.
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.
Originally this started as a "deduplicate a bunch of duplicated code in script commands" PR,
but as I was working on that, I discovered there's a lot more that needs to be done than
just deduplication.
Anything which needs a crewmate entity now calls `getcrewmanfromname(name)`, and anything which
just needs the crewmate's color calls `getcolorfromname(name)`. This was done to make sure that
everything works consistently and no copy/pasting is required. Next is the fallback; instead of
giving up and doing various things when it can't find a specific color, it now attempts to treat
the color name as an ID, and if it can't then it returns -1, where each individual command handles
that return value. This means we can keep around AEM -- a bug used in custom levels -- by not
doing anything with the return value if it's -1.
Also, for some reason, there were two `crewcolour` functions, so I stripped out the one in
entityclass and left (and modified) the one in the graphics class, since the graphics class also
has the `crewcolourreal` function.
If `setactivitytext` was the last line in a script,
the command would index the vector out of bounds.
I also modified the formatting to keep consistent
with the rest of the codebase.
These commands will change the colour and text of the next
activity zone that gets spawned. `setactivitycolour` takes all
textbox colors, and `setactivitytext` will take the text on
the next line. These commands were designed this way
to avoid breaking forwards compatibility.
When an activity zone is spawned through the
use of `createactivityzone`, and `i` is 35,
then it'll change the activity zone text to
"Press ENTER to interact".
This is a temporary vector that only gets used in mapclass::gotoroom().
It's always guaranteed to be cleared, so it's safe to move it off.
I'm fine with using references here because, like, it's a C++ STL vector
anyway - when we switch away from the STL (which is a precondition for
moving to C), we'll be passing around raw pointers here instead, and
won't be using references here anyway.
This is to make it so RNG is deterministic when played back with the
same inputs in a libTAS movie even if screen effects or backgrounds are
disabled.
That way, Gravitron RNG is on its own system (seeded in hardreset()),
separate from the constant fRandom() calls that go to visual systems and
don't do anything of actual consequence.
The seed is based off of SDL_GetTicks(), so RTA runners don't get the
same Gravitron RNG every time. This also paves the way for a future
in-built input-based recording system, which now only has to save the
seed for a given recording in order for it to play back
deterministically.
If spawned as a custom enemy (createentity entry 56), or spawned outside
of the rooms they spawn in in the main game, they will repeatedly clone
themselves every frame, which profusely leaks memory. In fact it quickly
causes a crash in 2.2 and previous, but 2.3 fixes that crash, so it just
keeps spawning enemies endlessly, which eventually lags the game, and
eventually can out-of-memory your system (bad!).
The problem is those movement types rely on entclass::setenemyroom() to
change their `behave` to be 11 or 13. Else, the new entity created will
still have `behave` 10 or 12, which will create ANOTHER entity in the
same way, and so on, and so forth.
So to fix this, just make it so if an enemy is still `behave` 10 or 12
by the end, then, just set it to -1. That way it'll stay still and won't
cause any harm.
I considered setting the `behave` to 11 or 13 respectively, but, that's
probably going farther than just fixing a memory leak, and anyways, it's
not that much useful for me as a custom level maker, and the entities
spawned aren't really controllable.
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 that desyncs my Nova TAS after re-removing the
1-frame input delay.
Quick stopping is simply holding left/right but for less than 5 frames.
Viridian doesn't decelerate when you let go and they immediately stop in
place. (The code calls this tapping, but "quick stopping" is a better
name because you can immediately counter-strafe to stop yourself from
decelrating in the first place, and that works because of this same
code.)
So, the sequence of events in 2.2 and previous looks like this:
- gameinput()
- If quick stopping, set vx to 0
- gamerender()
- Change drawframe depending on vx
- gamelogic()
- Use drawframe for collision (whyyyyyyyyyyyyyyyyyyyyyyyyyyy)
And now (ignoring the intermediate period where the whole loop order was
wrong), the sequence of events in 2.3 looks like this:
- gamerenderfixed()
- Change drawframe depending on vx
- gamerender()
- gameinput()
- If quick stopping, set vx to 0
- gamelogic()
- Use drawframe for collision (my mind has become numb to pain)
So, this means that all the player movement stuff is completely the
same. Except their drawframe is going to be different.
Unfortunately, I had overlooked that gameinput() sets vx and that
animateentities() (in gamerenderfixed()) checks vx. Although, to be
fair, it's a pretty dumb decision to make collision detection be based
on the actual sprites' pixels themselves, instead of a hitbox, in the
first place, so you'd expect THAT to be the end of the dumb parade. Or
maybe you shouldn't, I don't know.
So, what's the solution?
What I've done here is added duplicates of framedelay, drawframe, and
walkingframe, for collision use only. They get updated in gamelogic(),
after gameinput(), which is after when vx could be set to 0.
I've kept the original framedelay, drawframe, and walkingframe around,
to keep the same visuals as closely as possible.
However, due to the removal of the input delay, whenever you quick stop,
your sprite will be wrong for just 1 frame - because when you let go of
the direction key, the game will set your vx to 0 and the logical
drawframe will update to reflect that, but the previous frame cannot
know in advance that you'll release the key on the next frame, and so
the visual drawframe will assume that you keep holding the key.
Whereas in 2.2 and below, when you release a direction key, the player's
position will only update to reflect that on the next frame, but the
current frame can immediately recognize that and update the drawframe
now, instead of retconning it later.
Basically the visual drawframe assumes that you keep holding the key,
and if you don't, then it takes on the value of the collision drawframe
anyway, so it's okay. And it's only visual, anyway - the collision
drawframe of the next frame (when you release the key) will be the same
as the drawframe of the frame you release the key in 2.2 and below.
But I really don't care to try and fix this for if you re-enable the
input delay because it's minor and it'd be more complicated.
This fixes one of two desyncs in my Nova TAS.
The problem is that by adding two frames of edge-flipping to vertically
moving platforms, Viridian's framedelay is updated for one extra frame
after they step off of a vertically-moving platform. This then messes up
Viridian's drawframe for the rest of the TAS until they die in a
drawframe-sensitive trick.
The solution here is to only set the visual onroof/onground to 1
instead. The logical onroof/onground is still 2, so players still have
two frames of edge-flipping off of vertically-moving platforms - it just
won't really look like it (not that you could easily tell anyway).
This fixes a bug where the player's y-position would be incorrect if
they loaded a save that was on a conveyor and it was their first time
loading in since the game was opened.
This is because on the first load, the game creates a new player entity,
but on subsequent loads, the game re-uses the player entity. Subsequent
loads use mapclass::resetplayer(), which already has the newxp/newyp
fix, but as for the first time, the game does not set newxp/newyp.
So just set newxp/newyp, like in mapclass::resetplayer().
There is a pattern in the Super Gravitron that is meant to "staircase",
similar to the Gravitron in Intermission 2. Something like:
[]
[]
[]
[] []
[] []
Unfortunately, due to an oversight, this pattern can only ever produce 1
square or 4 squares, which look out of place.
Both gravitrons are state machines (of course). States 20 and 21 in the
Super Gravitron are this staircase pattern (state 20 spawns the squares
on the left, state 21 spawns the squares on the right).
The only way states 20 and 21 can be reached is through state 1, and the
only way state 1 can be reached is through state 3. The only way state 3
can be reached is through states 28, 29, 30, and 31.
In states 20 and 21, the variable used to keep track of the amount of
squares spawned is swnstate4. However, states 28, 29, 30, and 31 all end
up using swnstate4, and at the end of states 28 and 29, swnstate4 will
be 7, and at the end of states 30 and 31, swnstate4 will be 3. This
means if we go to states 20 and 21 after coming from states 28 and 29,
we will only get 1 square, and if we go to states 20 and 21 after coming
from states 30 and 31, we will only get 4 squares.
This can be clearly filed under a failure to reset appropriate state.
What's the solution here? Just reset swnstate4 in state 3, so there will
be 7 squares, as intended. This also fixes the bug for state 22 as well,
which is affected in the same manner.
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.
If you have completed No Death Mode, and entered the Master of the
Universe trophy room in the Secret Lab in over-30-FPS mode, it would
appear to start at one position before quickly zipping to another during
the deltaframes.
This is because it updates its position after the initial assignments of
lerpoldxp/lerpoldyp in entityclass::createentity().
Other entities do this too, and what's been done for them is to
copy-paste the lerpoldxp/lerpoldyp updates alongside the xp/yp updates.
However, instead of single-case patching this deltaframe glitch, I've
opted to fix ALL cases by simply moving the lerpoldxp/lerpoldyp
assignments to the end of the function, guaranteeing that all entities
that update their position after the initial assignment in the function
will not have any deltaframe glitches.
Of course, there's still the duplicate lerpoldxp/lerpoldyp updates in
entityclass::updateentities()... I'm not sure what to do about those.
vx/vy mean x-velocity and y-velocity... except here, where it seems like
they're used as extra parameters that do different things depending on
the entity. But it seems like at one point they were actually meant to
be the speed of the entity (this is the case for the unused decorative
particle entities), and then just never got renamed when they weren't.
The custom levels community named these two parameters meta1 and meta2
in the reference list of entities for the createentity() script command,
so that's what I'm naming them here. This will avoid confusion (I know
that some people reading this function have genuinely mistaken the vx/vy
for actually meaning x-velocity and y-velocity, simply because they were
named that way).
I have spelled out each overloaded version instead, and only the
overloads that are actually used - which just happens to be everything
except the 8-argument one. I don't want to deal with callers right now
(there are too many of them), so I'm not going to change the names that
the callers use, nor do I want to change the amount of arguments any
existing callers use right now - but we will have to deal with them in
one way or another when we move to C.
The script command createentity() is always an int. But not only that,
every time createentity() is used, its arguments are always treated like
ints. Always. I knew that vx/vy were floats because of the int casts in
the function, but I didn't even realize that xp/yp were floats, too,
until I checked just now! That's how much they're treated like ints.
All int casts in createentity() have also been removed, due to being
unnecessary (either because of us suppressing MSVC implicit conversion
warnings, or because there are now no longer any conversions happening).
During the final stretch, after Viridian turns off the Dimensional
Stability Generator, the map goes all psychedelic and changes colors
every 40 frames. Entities change their colors too, including conveyors,
moving platforms, and disappearing platforms.
But play around with the disappearing platforms for a bit and you'll
notice they seem a bit glitchy. If you run on them at the right time,
the tile they use while disappearing seems to abruptly change whenever
the color of the room changes. If there's a color change while they're
reappearing (when you die and respawn in the same room as them), they'll
have the wrong tile and look like a conveyor. And even if you've never
interacted with them at all, dying and respawning in the same room as
them will change their tile to something wrong and also look like a
conveyor.
So, what's the problem? Well, first off, the tile of every untouched
disappearing platform changing into a conveyor after you die and respawn
in the same room is caused by a block of code in gamelogic() that gets
run on each entity whenever you die. This block of code is the exact
same block of code that gets ran on a disappearing platform if it's in
the middle of disappearing.
As a quick primer, every entity in the game has a state, which is just a
number. You can view each entity's state in
entityclass::updateentities().
State 0 of disappearing platforms is doing nothing, and they start with
an onentity of 1, which means they turn to state 1 when they get
touched. State 1 moves to state 2. State 2 does some decrementing, then
moves to state 3 and sets the onentity to 4. State 3 also does nothing.
After being touched, state 4 makes the platform reappear and move to
state 5, but state 5 does the actual reappearing; state 5 then sets the
state back to 0 and onentity back to 1.
So, back to the copy-pasted block of code. The block of code was
originally intended to fast-forward disappearing platforms if they were
in the middle of disappearing, so the player respawn code would properly
respawn the disappearing platform, instead of leaving it disappeared.
What it does is keep updating the entity, while the state of the entity
is 2, until it is no longer in state 2, then sets it to state 4.
Crucially, the original block of code only ran if the disappearing
platform was in state 2. But the other block of code, which was
copy-pasted with slight modifications, runs on ALL disappearing
platforms in final stretch, regardless of if they are in state 2 or not.
Thus, all untouched platforms will be set to state 4, and state 4 will
do the animation of the platform reappearing, which is invalid given
that the platform never disappeared in the first place. So that's why
dying and respawning in the same room as some disappearing platforms
during final stretch will change their tiles to be conveyors.
It seems to me that doing anything with death is wrong, here. The root
cause is that map.changefinalcol() "resets" the tile of every
disappearing platform, which is a function that gets called on every
color change. The color change has nothing to do with dying, so why
fiddle with the death code?
Thus, I've deleted that entire block of code.
What I've done to fix the issue is to make it so the tile of
disappearing platforms aren't manually controlled. You see, unlike other
entities in the game, the tile of disappearing platforms gets manually
modified whenever it disappears or reappears. Other entities use the
tile as a base and store their tile offset in the separate walkingframe
attribute, which will be added to the tile attribute to produce the
drawframe, which is the final thing that gets rendered - but for
disappearing platforms, their tile gets directly incremented or
decremented whenever they disappear or reappear, so when
map.changefinalcol() gets ran to update the tile of every platform and
conveyor, it basically discards the tile offset that was manually added
in.
Instead, what I've done is make it so disappearing platforms now use
walkingframe, and thus their final drawframe will be their tile plus
their walkingframe. Whenever map.changefinalcol() gets called, it is now
free to modify the tile of disappearing platforms accordingly - after
all, the tile offset is now stored in walkingframe, so no weird
glitchiness can happen there.
Custom levels can have warp lines. If you have a warp line and a warping
background in the same room, the warp line takes precedence over the
warp background.
However, whenever you enter a room with a warp line and warp background,
any entities on the warping edges will be drawn with screenwrapping for
one frame, even though they never wrapped at all.
This is due to frame ordering: when the warp line gets created,
obj.customwarpmode gets set to true. Then when the screen edges and
warping logic gets ran, the very first thing that gets checked is this
exact variable, and map.warpx/map.warpy get set appropriately - so
there's no way the entity could legitimately screenwrap.
However, that happens in gamelogic(). gamelogic() is also the one
responsible for creating entities upon room load, but that happens after
the obj.customwarpmode check - so when the game gets around to rendering
in gamerender(), it sees that map.warpx or map.warpy is on, and draws
the screenwrapping, even though map.warpx/map.warpy aren't really on at
all. Only when gamelogic() is called in the frame later do map.warpx and
map.warpy finally get set to false.
To fix this, just set map.warpx and map.warpy to false when creating
warp lines.
I just spotted this one - if vy isn't bounds-checked, this causes bogus
input from the createentity() script command to commit Undefined
Behavior. Should've spotted this one when I was adding bounds checks to
the rest of createentity() earlier, but at least it's fixed now.
This replaces all raw ed.level accesses with new setter and getter
funcs, which makes it easier to add bounds checks later. And I've also
removed all the manually-written bounds checks, since they will go into
the new getter and setter.
To get the room properties of a specific room, you use
editorclass::getroomprop(), which returns a pointer to the room
properties - then you just read off of that pointer. To set a room
property, you use editorclass::setroom<PROP>(), where <PROP> is the name
of the property. These are maintained using X macros to avoid
copy-pasting. editorclass::getroompropidx() is a helper function and
shouldn't be used directly.
I will need to separate these into two different variables because I
will need to move logical onground/onroof assignments to the start of
gamelogic() - if I kept them together, however, that would change the
visuals of onground/onroof, which I want to keep consistent with 2.2.
This once again fixes the facing directions of crewmates upon room load,
except now it covers more cases.
So, here is the saga so far:
- 2.0 (presumably) to 2.2: crewmate direction fix is special-cased at
the end of mapclass::loadlevel(). Only covers crewmates created during
the room load, does not cover crewmates created from scripts, only
covers state 18 of crewmates.
- 2.3 currently (after #220): crewmate direction fix is moved to
entityclass::createentity(), which covers every avenue of crewmate
creation (including from scripts), but still only covers state 18.
- This commit: crewmate direction fix now covers every possible state of
the crewmate, also does not copy-paste any code.
What I've done instead is to make it so createentity() will immediately
call updateentities() on the pushed-back entity. This is kludge-y, but
is completely okay to do, because unlike other entities, crewmate
entities never change their state or have any side-effects from
double-evaluation, meaning calling updateentities() on them is
idempotent and it's okay to call their updateentities() more than once.
This does have the slight danger that if the states of crewmates were to
change in the future to no longer be idempotent, this would end up
resulting in a somewhat hard-to-track-down double-evaluation bug, but
it's worth taking that risk.
This fix is not applied to entity 14 (the supercrewmate) because it is
possible that calling updateentities() on it will immediately remove the
entity, which is not idempotent (it's changing the state of something
outside the object). Supercrewmates are a bit difficult to work with
outside of the main game anyways, and if you spawn them you could
probably just use the changedir() script command to fix their direction,
so I'm not inclined to fix this for them anyway.
This copy-pasted code only existed because the previous loop order was
incorrect and rendered entities before they would get properly updated
by the fixed render function. Now, the fixed render function is
guaranteed to be called before the render function, so we can rely on
that to update the drawframe and realcol of entities instead of
duplicating the code ourselves in createentity().
The drawframe assignment is still kept to fix the case where dying while
completestop is active (i.e. during a trinket or crewmate rescue
cutscene) and respawning in a different room won't turn everything into
Viridian sprites.
These float attributes are assigned to, and then never read again. The
coordinate systems of blocks are a bit of a mess - some use xp/yp, some
use xp/yp and rect.x/rect.y - but I can confidently say that these are
never used, because it compiles fine if I remove the attributes from the
class, plus remove all assignments to it.
