The level debugger is toggleable in playtesting mode by pressing Y.
You can toggle whether or not the game is paused inside of the debugger
by pressing TAB. The debugger screen allows you to see entity and block
properties, and allows you to move them around.
This is what got saved to the area part of the <summary> tags, and it
was specifically set upon pressing ACTION to save in the map menu.
Which meant tsave.vvv may not get an accurate area name (notably
"nowhere" if you hadn't quicksaved before in that session) even though
it's not displayed anywhere so it didn't really matter. But this
variable can be removed - there's only one place where <summary> is
written for both quicksaves and telesaves, so that now gets the area
at saving time.
Fun fact: custom level quicksaves also have a <summary> tag, and it's
even less functional than the one in tsave.vvv, because it stores
whatever main-game area name applies to your current coordinates.
So I simply filled in the level's name instead (just like what the
actual save box says).
Game::telesummary and Game::quicksummary stored the summary string for
the save files - which is the <summary> tag that says something like
"Space Station, 10:30:59". The game only ever displays the quicksave
variant of these two, for "Last Save:" on the map menu's SAVE tab.
So the telesave has a <summary> too, but it's never displayed anywhere.
(In fact, the area is often set to "nowhere"...)
However, the summary strings have another function: detect that both
the telesave and quicksave exist. If a summary string for a save is
empty, then that save is considered not to exist.
I'm refactoring the summary string system, by making the new variables
Game::last_telesave and Game::last_quicksave of type struct
Game::Summary. This struct should have all data necessary to display
the summary string at runtime, and thus translate it at runtime (so
we don't store a summary in a certain language and then display it in
the wrong font later - the summary can always be in the current
language). It also has an `exists` member, to replace the need to
check for empty strings.
The <summary> tag is now completely unused, but is still written to
for older versions of the game to read.
(This commit does not add the new string to the language files, since
Terry now added it separately in his own branch)
It used to take a single int: the area number returned by
mapclass::area(roomx, roomy). All uses of currentarea() were called
with an extra area() call as its argument. Additionally, there's a
good reason why currentarea() should have the room coordinates: in one
of the cases that it's called, there's a special case for the ship's
coordinates. This results in the SAVE screen in the map menu being able
to show "The Ship", while the continue screen shows "Dimension VVVVVV"
instead. Therefore, why not put that exception inside currentarea()
instead, and remove a few callsite map.area() wrappers by making
currentarea() take the room x and y coordinates?
Language folders can now have a graphics folder, with these files:
- sprites.png and flipsprites.png: spritesheets which contain
translated versions of the word enemies and checkpoints
- spritesmask.xml: an XML file containing all the sprites that should
be copied from the translated sprites and flipsprites images to
the original sprites/flipsprites.
This means that the translated spritesheets don't have to contain ALL
sprites - they only have to contain the translated ones. When loading
them, the game assembles a combined spritesheet with translated sprites
replacing English ones as needed, and this sheet is used to visually
substitute the normal sprites at rendering time.
It's important to note that even if 32x32 enemies have pixel-perfect
hitboxes, this is only a visual change. This has been discussed several
times on Discord - basically we don't want to give people unfair
advantages or disadvantages because of their language setting, or
change existing gameplay and speedruns tactics, which may depend on the
exact pixel arrangements of the enemies. Therefore, the hitboxes are
still based on the English sprites. This should be basically
unnoticeable for casual players, especially with some thought from
translators and artists, but there will be an option in the speedrunner
menu to display the original sprites all the time.
I removed the `VVV_freefunc(SDL_FreeSurface, *tilesheet)` in
make_array() in Graphics.cpp, which frees grphx.im_sprites_surf and
grphx.im_flipsprites_surf. Since GraphicsResources::destroy() already
frees these, it looks like the only purpose the one in make_array()
serves is to do it earlier. But now we need them again later (when
switching languages) so let's just not free them early.
It'll start working in the next commit... See the description there.
(This commit does not add the new strings to the language files, since
Terry now added them separately in his own branch)
In 8484b36198, I fixed the title screen
showing up if you go to the language screen from in-game, while not
having any language files. There was also one other possible way to get
this to happen that I missed though: if you do have language files, and
you have not set your language yet, and you start a playtest via the
command line (e.g. by using Ved), and you then change the language
from the in-game options. That is now fixed.
I really thought I was going to need to block changing the language
in-game altogether, but activity zone prompts are now fixed and the
only obvious problem I can think of right now is having a dialogue
open, so I just disable the language option if a textbox is displayed.
(like how the map menu only has the save option if a script is running)
If you've never set a language before (<lang_set> is not 1), then the
language screen will show up before the title screen. Selecting the
language will then make the title screen show up.
If no language files are present, the old logic for handling this was
to simply show the language screen at startup anyway, and let it
display the error message that language files are missing, as a warning
that the game is not packaged correctly. However, this logic has two
flaws:
- If the user has ever had language files and set a language before
(in a VVVVVV on that computer), the warning element is gone because
the language screen is not shown in that case - the game is simply in
English
- If the user has never set a language before, and then goes to the
language screen later via the menu, they will be sent to the title
screen, even if they were in-game. The main menu will also be broken.
The new way is to not show the language screen at startup if language
files are missing, and to change the logic so that you will only be
sent to the title screen if you actually haven't seen the title screen
yet.
I will also add a proper warning that fonts or language files are
missing by adding a message in the bottom left corner (in place of the
MMMMMM installed message).
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`.
For some reason, the credits button was always specifically removed from
M&P builds. After some discussion with Terry Cavanagh on the VVVVVV
Discord server, we agreed that there was no reason this should be
removed. So, it's getting put back in.
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.
This adds an anonymous enum for music tracks and replaces all calls to
music.play and music.niceplay that use integer literals. Additionally,
this is also done for integer literals for cl.levmusic (except 0) and
music.currentsong where appropriate, but _not_ the music areamap because
that would not make it look very aesthetically pleasing in the code.
This is not a named enum (that can be used for strict typechecking)
because music track IDs are essentially part of the API of the game -
almost every custom level uses these numbers. This is just to make the
source code more readable without needing a comment to denote what
number is what track.
If you had the map button held before the game transitioned to the
credits and ending picture sequences, then you wouldn't be able to skip
them, because those gamemodes don't have logic to detect when you've
released the map button.
To fix this, just implement the map button release logic.
We do need a better input system soon...
Ever since 2.3, if you bind a controller button to the "menu" action
(i.e. back/escape) you won't be able to change that button to any other
action, because pressing it anywhere in the binding menu will exit to
the previous menu, without applying the binding.
I know action sets will overhaul everything, but 2.4 may (probably
"should") come out before we have action sets. This part is very
broken, and the fix is very easy: just move the bind-assigning code to
above the menu-return-on-esc code, and add a return.
I thought 2.2 already had separate map and interact gamepad bindings,
and they simply got neglected and broken with 2.3's split Enter/E key
option. But actually, the new split Enter/E option also applied to
gamepad buttons, and a separate interact binding was added, without
really indicating anything if Enter and E are not split. And I guess
using the same button for map and interact by default also makes sense
for simplicity...
This commit makes sure the button glyph displayed in-game is at least
the correct button. The gamepad bindings menu is also slightly modified
to darken the interact option - the button glyphs code now
automatically causes them to show equal buttons anyway, so it wasn't
too big of a change to also darken the line and disable the binding
option. To me this says: "the interact key is fixed to be the same as
enter right now, but there is a way to change it."
It's still not ideal of course, and I know a similar change to the
gamepad menu to hide the interact option was rejected a year ago
because action sets would already fix it, but it's a year later now,
and showing misleading button glyphs should be fixed in 2.4, whether it
will already have action sets or not (And at this point I think the
plan already is to keep the existing input system for 2.4)
And it's a 3 line diff to darken and disable the option, compared to
fully hiding the option.
This fixes a regression where the behavior of duplicate player entities
is different, causing a gameplay section in Vespera Scientifica to be
impossible, as described in #903.
In the level, you are allowed to flip in mid-air. Vespera accomplishes
this by having two duplicate player entities stuck in a platform. One of
them is responsible for letting the player flip in one direction, and
one of them is responsible for letting them flip in the other.
In 2.3, this works because in order for a player entity to flip,
`game.jumppressed` is checked, and the entity will flip if
`game.jumppressed` is greater than 0, then `game.jumppressed` will be
set to 0. In this way, whenever a player entity flips, it will set
`game.jumppressed` to 0, so whenever the next player entity is
evaluated, `game.jumppressed` is 0 and thus _that_ entity will not flip.
This is because the for-loop surrounds both the `game.jumppressed` check
and flipping the entity. In 2.4 after #609 and subsequent patches,
however, this is not the case. Here, the for-loop only surrounds
flipping the entity. Therefore, the `game.jumppressed` check is
evaluated only once. So, it will end up flipping every player entity if
the entities are eligible. In this case, one of them is eligible twice,
resulting in the game flipping gravitycontrol four times, which is
essentially the same as not flipping at all (except for all the sound
effects).
Hence, the fix here is to make it so the for-loop surrounds the
`game.jumppressed` check.
Now, this doesn't mean that the intent of #609 - that duplicate player
entities have the same initial velocity applied to them when flipping -
has to be removed. We can just put the for-loops back in. But I
carefully implemented them in such a way that the overall function is
not quadratic, i.e. O(n²). Instead, there's a pass done over the
`obj.entities` vector beforehand to store all indexes of a player entity
in a temporary vector, and then that vector is used to update all the
player entities. In this manner, the function is still linear - O(n) -
over the number of entities in the room.
I tested this to make sure that no previous regressions popped up again,
including #839, #855, and #887. And #484 is still resolved.
Fixes#903.
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
In general, "temp" is a bad name because it could mean anything. In this
case the buffer isn't really temporary and it's only used for drawing
the menu with a certain offset, so I made it use a better name. But also
because I'm going to be adding temporary buffers so I don't want the
names to be confused.
colourTransform is a struct with only one member, a Uint32. The issue
with `Uint32`s is that it requires a bunch of bit shifting logic to edit
the colors. The issue with bit shifting logic is that people have a
tendency to hardcode the shift amounts instead of using the shift amount
variables of the SDL_PixelFormat, which makes it annoying to change the
color masks of surfaces.
This commit fixes both issues by unhardcoding the bit shift amounts in
DrawPixel and ReadPixel, and by axing the `Uint32`s in favor of using
SDL_Color.
According to the SDL_PixelFormat documentation (
https://wiki.libsdl.org/SDL2/SDL_PixelFormat ), the logic to read and
draw to pixels from colors below 32-bit was just wrong. Specifically,
for 8-bit, there's a color palette used instead of some intrinsic color
information stored in the pixel itself. But we shouldn't need that logic
anyways because we don't use colors below 32-bit. So I axed that too.
This allows translators to test all text boxes in the scripts. It
doesn't run the scripts themselves - it only shows the basic appearance
of each text box individually, so context may be lost but it's good to
have a way to see any text boxes that might otherwise not be easily
seen because they require specific circumstances to appear.
I would, of course, recommend translators to translate the roomnames
while playing the full game (optionally in invincibility) so they can
immediately get all the context and maybe the most inspiration. And if
you want to go back into a specific level, then there's always the time
trials and intermission replays which will give you full coverage of
all the room names.
However, the time trials weren't really made for room name translation.
They have some annoying features like the instant restart when you
press ENTER at the wrong time, they remove context clues like
teleporters and companions, but the worst problem is that the last room
in a level is often completely untranslatable inside the time trials
because you immediately get sent to the results screen...
So, I added a new menu in the translator options, "explore game", which
gives you access to all the time trials and the two intermissions, from
the same menu. All these time trials (which they're still based off of,
under the hood) are stripped of the annoying features that come with
time trials. These are the changes I made to time trial behavior in
translator exploring mode:
- No 3-2-1-Go! countdown
- No on-screen time/death/shiny/par
- ENTER doesn't restart, and the map menu works. The entire map is also
revealed.
- Prize for the Reckless is in its normal form
- The teleporters in Entanglement Generator, Wheeler's Wormhole and
Level Complete are restored as context for room names (actually, we
should probably restore them in time trials anyway? Their "press to
teleport" prompt is already blocked out in time trials and they do
nothing other than being a checkpoint. I guess the reason they were
removed was to stop people from opening the teleporter menu when that
was not specifically blocked out in time trials yet.)
- The companions are there at the end of levels, and behave like in no
death mode (become happy and follow you to the teleporter). Also for
context.
- At the end of each level, you're not suddenly sent to the menu, but
you can use the teleporter at your leisure just like in the
intermission replays. In the Final Level, you do get sent to the menu
automatically, but after a longer delay.
I made another mark on VVVVVV: don't be startled, I added gamestates.
I wanted all teleporters at the end of levels to behave like the ones
at the end of the intermission replays, and all handling for
teleporting with specific companions is already done in gamestates, so
rather than adding conditional blocks across 5 or so different
gamestates, it made more sense to make a single gamestate for
"teleporting in translator exploring mode" (3090). I also added an
alternative to having to use gamestate 3500 or 82 for the end of the
final level: 3091-3092.
One other thing I want to add to the "explore game" menu: a per-level
count of how many room names are left to translate. That shouldn't be
too difficult, and I'm planning that for the next commit.
This involves loc::gettext_roomname and loc::gettext_roomname_special.

This commit adds most of the code changes necessary for making the game
translatable, but does not yet "unhardcode" nearly all of the strings
(except in a few cases where it was hard to separate added
loc::gettexts from foundational code changes, or all the localization-
related menus which were also added by this commit.)

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

2.0.18 officially releases in November.
Fixes#831.
