There's a problem in #1224 where it breaks spawning custom activity
zones. After a bit of confusion after this was reported, I realized
that I removed the fallback from `getcrewman` and changed the return
value to `-1` if the entity isn't found, to avoid returning the wrong
entity (entity 0, aka probably the player).
Unfortunately, it seems like a ton of levels (including my older ones)
rely on this behavior.
Creating custom activity zones is a long process which uses a bunch of
unintended behaviour, which includes targeting a crewmate with color
35. With the change I mentioned earlier, the `getcrewman` function
would return `-1` instead, which was out of bounds of the entity array,
so the game avoided spawning the activity zone at all. The prior
behaviour of falling back to entity 0 (most likely the player) would
spawn the activity zone around the player instead.
Nowadays, I try to spawn a crewmate with color 35 anyways so I can
control where the box spawns (instead of on the player always), however
most people don't (and haven't) so reverting this change seems best for
now.
If we wanted to reintroduce the `-1` fallback in the future, things
that call `getcrewman` would have to check for `-1` and use `0`
instead, but that would require a lot more testing and studying where
it's used, and I'd rather squash this bug quickly and worry about
cleanliness later.
Entity colors are just integers. Their colour ID gets passed through a
big switch, returning different RGB values depending on the colour ID
(and can also get affected by randomness or other game state.)
But because of this, there's a bunch of random numbers floating around,
with no actual description on what they are other than comments which,
while most of the time are accurate, only exist in the switch.
To fix this, this commit adds a new enum which labels every colour.
While we can't use it as a type (as we need to allow colours outside of
what are defined, in case people want a "pure white", and scripting can
set any colour ID they want), colours have to stay as `int`.
In an effort to remove magic numbers, I've given every entity type a
name. Hopefully I didn't miss anywhere.
Also, add `createentity` case 100 for backwards compatibility.

Commit 53d725f78a, intended to fix an
overzealous commit, was itself overzealous. This is because it applied
to all entities when it should only apply to entity-emitting entities.
To fix this, `entityclonefix` needs to no-op if the entity is not an
entity emitter.
Fixes#1176.
Commit 4f881b9e26 fixed a duplication bug
where enemy movement types 10 and 12 would keep duplicating itself on
every frame if it was spawned outside of the rooms they were supposed to
be used in the main game. The downside was that this was an overzealous
fix and unintentionally broke some cases that were working before.
As brought to my attention by Ally, you can no longer place an edentity
with a `p1` of 10 or 12 (translating to movement type 10 or 12) in the
proper rooms and have it spawn perfectly working entities (that don't
clone on themselves every frame), whereas you could in 2.2. This is
considered a regression from 2.3.
So the problem here is that the reason the two emitter entities were so
dangerous outside their respective rooms is because the entity they
spawned (`createentity` entry 1) checked if it was in the correct rooms,
and if so, it would call `setenemy`, and `setenemy` would set the
`behave` attribute (movement type) correctly, and so the new entity
would have a different `behave` that wouldn't be the exact same `behave`
as the previous one, so it wouldn't be a duplicate emitter entity.
The previous `entityclonefix` worked okay for entry 1, because it would
only be run if the room checks failed and `setenemy` wasn't called, but
it broke a previously-working case for entry 56, because it was always
run for entry 56.
So the best way to check if we have a dangerous entity is not by seeing
if it is still `behave` 10 or 12 at the end of entity creation - because
10 or 12 could be harmless under the right conditions - but by checking
if the right conditions were satisfied, and if not, then neutralize the
entity.
I considered making the emitter entities work everywhere - which would
be simpler - but I didn't want to go too far and add a new feature,
especially in a minor release.
The translations for the prompts used to be looked up at creation time
(when the room is loaded or the activity zone is otherwise spawned),
which meant they would persist through changing the language while
in-game. This would look especially weird when the languages you switch
between use different fonts, as the prompt would show up in the old
language in the new language's font.
This problem is now fixed by letting the activity zone block keep
around the English prompt instead of the translated prompt, and letting
the prompt be translated at display time. This fixes a big part of the
reason I was going to disable changing the language while in-game; I
might only need to do it while textboxes are active now! :)
This commit removes the `NO_EDITOR` and `NO_CUSTOM_LEVELS` defines,
which cleans up the code a lot, and they weren't really needed anyways.
This commit also disables the editor on the Steam Deck, and adds a
program argument to re-enable the editor, `-enable-editor`.
This adds an anonymous enum for time trial indexes (e.g. the bestrank,
bestlives, etc. arrays and timetriallevel), and replaces all integer
literals with them.
Just like the unlock arrays, these are indexes to an array in XML save
files, so the numbers matter, and therefore should not use strict
typechecking.
This adds an anonymous enum for the unlock and unlocknotify arrays and
unlocknum function, and replaces all integer literals with them.
This is not named and thus cannot be used for strict typechecking
because these are actually indexes into an array in XML save files, so
the numbers themselves matter a lot.
This replaces the swngame int variable with a named enum and enforces
strict typechecking on it.
Strict typechecking is okay here as the swngame variable is not part of
the API surface of the game in any way and is completely internal.
And just to make things clear, I've added a SWN_NONE enum to use for
initialization, because previously it was being initialized to 0, even
though 0 was the Gravitron.
This adds an anonymous enum for sound effects and replaces all calls to
music.playef that use integer literals.
This is not a named enum (that can be used for strict typechecking)
because sound effect IDs are essentially part of the API of the game -
many custom levels use these numbers. This is just to make the source
code more readable without needing a comment to denote what number is
what sound.
For some reason, the accessibility option that was meant to disable
flashes doesn't disable ALL flashes, only screen flashes and screen
shaking. This commit disables a lot more, most importantly randomness
in colors, the player flashing on death/respawn, and teleporters
flashing.
As reported by Lilithtreasure on the VVVVVV Discord server, it is
possible to get gray moving platforms and enemies in the main game.
This happens if you play the main game after loading a custom level with
a room that is gray at the same coordinates. E.g. if you play a custom
level with a gray room at (12, 4), then exit and go to Gantry and Dolly
in the main game which is also at (12, 4), then the platforms there
would be gray too.
This is because there is a missing map.custommode check.
After discussing with Ally and Dav, we came to the agreement that this
is basically useless since the prompt will always be centered and take
up most of the horizontal space of the screen.
And the x-position was only added as an offset because at some point,
there was a missing space from the side of the "- Press ENTER to
Teleport -" prompt, and the offset was there so people could mimic the
prompt accordingly. But that was fixed at some point, so it's useless
now.
Activity zones need to be in the interface font if the message is from
the system (like Press ENTER to activate terminal, which may be in a
different language) and in the level font if it's a customized message
(setactivitytext).
Graphics::drawtextbox was counting the textbox width and height in
8x8 characters, even including the borders as characters, so it'd need
to be told what the font for the textbox is, and then probably only the
height needs to be adapted to the font and not the width because that's
adapted to the screen width... So just call Graphics::drawpixeltextbox
directly instead. It was already weird enough how actual cutscene
textboxes called Graphics::drawtextbox with x/8, y/8 before the
previous commit, (when you already have the pixel width and height!)
only to have that be a wrapper for drawpixeltextbox by doing x*8, y*8.
The `point` struct was a relic of ActionScript and was added because of
the Flash 'point' object. However, it seems like Simon Roth didn't
realize that SDL has its own point struct.
With this, `Maths.h` can be un-included from a couple headers, which
exposes the fact that `preloader.cpp` was relying on `Maths.h` being
transitively included from `Graphics.h`.
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.
