Misa 43bebecf3b Make room names own their own memory
This makes it so room names are no longer pointers to someone else's
memory, and instead to set them you use `mapclass::setroomname`. If the
string is short enough to fit in a static, no-alloc buffer, then it gets
copied there. Otherwise, a new heap allocation is made that duplicates
the string, and the new pointer is used instead.

This makes it possible for room names to contain arbitrary data whose
origin is temporary (e.g. from a script command that could be added in
the future).

Misa 3fc23f2b2c Add `-console` option on Windows
This adds the `-console` command-line option (for Win32 only) so the
game can spawn an attached console window which will contain all console
output.

This is to make it easier for people to debug on Windows systems.
Otherwise, the only way to get console output would be to either compile
the application as a console app (i.e. switch the subsystem to console)
- which is undesirable for regular users as this makes it so a console
is always spawned even when unwanted - or launch the game with shell
arguments that make it so output is redirected to a file.

As a result, color checking support is factored out of vlog_init() into
its own function, even though we don't support colors on Windows.

Misa 9def8fd704 Seed with frame counter instead of `SDL_GetTicks`
Using SDL_GetTicks() to seed the Gravitron RNG caused many
reproducibility issues while syncing https://tasvideos.org/7575S . To
fix this, add a frame counter, which is a number that is incremented
every frame and never resets, and use it instead.

If someone needs to switch back to SDL_GetTicks() for old TASes, then
provide the -seed-use-sdl-getticks command-line option for them.

Misa e7e74bb8ab Add commit hash & date to `-version` flag output
This prints the commit hash and date in the same order as they are
printed on the title screen.

Misa 52124f7010 De-duplicate release version
I'm fine with putting the release version in a header file, thus
necessitating the need to recompile every file that includes it if it's
changed, simply because it's not supposed to be changed that often.

The SDL_arraysize is necessary because sometimes we'll have subreleases
(e.g. 2.4.1, 2.4.2, 2.4.3), and who knows, maybe we'll get to 2.10
someday.
2022-08-23 00:00:39 -07:00
Misa 4bf5e5e6a0 Optimize recompilation from changing commit hash
This reworks how the commit hash and date are compiled so that if
they're changed (and they're changed often), only one source file needs
to be recompiled in order to update it everywhere in the game, no matter
how many source files use the hash or date.

The commit hash and date are now declared in InterimVersion.h (and they
need `extern "C"` guards because otherwise it results in a link fail on
MSVC because MSVC is stupid).

To do this, what now happens is that upon every rebuild,
InterimVersion.in.c is processed to create InterimVersion.out.c, then
InterimVersion.out.c is compiled into its own static library that is
then linked with VVVVVV.

(Why didn't I just simply add it to the list of VVVVVV source files?
Well, doing it _now_ does nothing because at that point the horse is
already out of the barn, and the VVVVVV executable has already been
declared, so I can't modify its sources. And I can't do it before
either, because we depend on the VVVVVV executable existing to do the
interim version logic. I could probably work around this by cleverly
moving around lines, but that'd separate related logic from each other.)

And yes, the naming convention has changed. Not only did I rename
Version to InterimVersion (to clearly differentiate it from
ReleaseVersion, which I'll be adding later), I also named the files
InterimVersion.in.c and InterimVersion.out.c instead of
InterimVersion.c.in and InterimVersion.c.out. I needed to put the file
extension on the end because otherwise CMake wouldn't recognize what
kind of language it is, and I mean like yeah duh of course it doesn't,
my text editor doesn't recognize it either.

Dav999-v 10acd67377 Add support for start position via level XML for CLI playtesting
As already described in cc61194bed, as
well as Ved's commits from the last almost two weeks, starting VVVVVV
from Ved for playtesting could be made a lot faster by "preloading" the
game - letting it do all its asset loading in the background without
creating a window - and then waiting until the level is passed in via
stdin. There's only one problem left with this approach: VVVVVV
currently expects the starting position to be passed via command line
arguments, which isn't known yet at the time we'd like to start VVVVVV.
Therefore, this commit allows passing the starting position via the
level XML, instead of via arguments.

The extra XML looks like this, and is added next to the <Data> tag:

    <Playtest>
        <playx>214</playx>
        <playy>112</playy>
        <playrx>100</playrx>
        <playry>100</playry>
        <playgc>0</playgc>
        <playmusic>4</playmusic>
    </Playtest>

This is handled similarly to how the equivalent arguments are handled:
when the level metadata is loaded for CLI playtesting, we also try to
find this tag, and if it exists, it sets the same variables that the
arguments would have otherwise set.

Misa cc61194bed Move `SDL_ShowWindow` to after assets are loaded
This is a minor optimization to streamline the experience of Ved
playtesting. Previously, the user would have to wait for all the assets
to load when launching playtesting (most of the time, I suspect, is
taken up by loading music from a vvvvvvmusic blob). With this
optimization, however, the game can be launched in the background and
its assets can be loaded, while it blocks on STDIN input. During this
time, the user in Ved will be choosing where to start playtesting. After
Ved provides STDIN input, then the window will be created and appears
instantaneously.

This also fixes a related issue in which providing an invalid
playtesting level name would result in a brief window flash that gets
instantly destroyed. With this, if the level is invalid then no window
is ever shown at all.

Misa a46c49c89a Add `-version` command-line argument
Probably should have done this earlier in 2.3, but better late than
never.

This makes it easier for third-party programs like Ved to detect what
version of the game this is.

Slightly quick-n-dirty for now, I'll de-duplicate the version number
later, and add commit hash and date if applicable.

Misa 98cb415675 Enumify all fade modes
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.

Misa 84279354e5 `cleanup`: Don't `savestatsandsettings` if filesystem not init
This isn't necessary, but it does silence these annoying logs if you
pass an invalid argument or don't have data.zip:

    [ERROR] Could not get window size: Invalid renderer
    [WARN] Stats not loaded! Not writing unlock.vvv.
    [ERROR] Could not get window size: Invalid renderer
    [WARN] Settings not loaded! Not writing settings.vvv.

To do this, I've added FILESYSTEM_isInit().

Misa a6b076e234 Explicitly zero declared `struct ScreenSettings`s
Performance cost is negligible and well worth being safe in case there
are more members added in the future but we forget to initialize them.
2021-12-25 00:30:10 -08:00
Misa 1e157f3cc9 De-C++-ify `struct ScreenSettings`
This includes:
- Removing the constructor in favor of actually being able to see that
  there's an actual function called being made initializing the struct
- Removing the use of a reference in Screen::init() in favor of using a
  pointer
- Adding the struct qualifier everywhere (it's not much typing),
  although technically you could typedef it in C, but I'd rather much
  not typedef just to remove a tag qualifier

Misa d0ffafe117 Extern `gameScreen`, remove `screenbuffer`
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.
2021-12-25 00:29:28 -08:00
Misa 0c1f756af8 Switch over to using `SDL_GetTicks64()`
SDL_GetTicks64() is a function that got added in SDL 2.0.18, which is
just an SDL_GetTicks() without a value that wraps every ~49 days,
instead wrapping after the sun explodes and kills us all. Oh sorry,
didn't mean to get existential.

For now, put this behind an SDL_VERSION_ATLEAST guard, which will be
removed when SDL 2.0.18 officially releases and we can update to it.

Misa 5533215019 Use `SDL_NORETURN`
I misread SDL's code and thought that SDL's `begin_code.h` was internal
only to SDL. It turns out you get it when you include basically any
header, such as `SDL_stdinc.h`. So use it directly instead of copying it
for our own.
2021-09-27 10:32:23 -07:00
Misa eabb3941fd Mark `VVV_exit` implementation as `VVV_NORETURN`

Misa dbe9f7c2a0 Declare `emscriptenloop` as `static`

Misa 1d0401ef83 Move Emscripten includes to top of `main.cpp`
All system header includes should come before project-specific includes

leo60228 d40af63aa3 Split Func_input and Func_delta when unfocused
Without this, `fixedloop` will loop infinitely until focus is regained.
However, Emscripten won't actually know that focus is regained until
`fixedloop` returns.

Misa e9ec34e1f5 Call teleporterrenderfixed in TELEPORTERMODE
This restores it to 2.2 behavior, where the cutscene bars timer also
ticked in TELEPORTERMODE. It was a 2.3 regression that the cutscene bars
timer didn't tick there.

This makes it so if you manage to get stuck in TELEPORTERMODE when a
cutscene ends, the cutscene won't be stuck on untilbars() waiting for
the cutscene bars to go away, since the cutscene bars timer now ticks.

Misa 8bff287907 Rename edentity to customentities
This fixes the fact that the name of the singular type is plural, but
the name of the plural array is singular. Which has always annoyed me,
too. Also this makes it more clear that custom entities don't have much
to do with the editor.
2021-09-01 15:30:02 -07:00
Misa 47d01277bf Rename edentities to CustomEntity
That's what it is - it's an entity in a custom level. Not something to
do with the editor, necessarily. Like before, the name of the XML
element will remain the same.
2021-09-01 15:30:02 -07:00
Misa a23014350f Move all editor-specific attributes to a new editorclass
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.
2021-09-01 15:30:02 -07:00
Misa 6f0177ec04 Move editor functions to separate header
Editor functions now live in Editor.h, which is a new file - the

2021-09-01 15:30:02 -07:00
Misa 3e380e23fb Rename editor.h to CustomLevels.h
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.

Misa c58c357a81 Simplify Flip Mode rendering code with SDL_RenderCopyEx
Previously, Flip Mode rendering had to be complicated and allocate
another buffer to call FlipSurfaceVerticle, and it was just a mess.

Instead, why not just do SDL_RenderCopyEx, and let SDL flip the screen
for us? This ends up pretty massively simplifying the rendering code.

Misa c68a274c4f Add command-line options to force-enable/disable color

Misa ac85f57441 Add colors to logging
This includes the bold as well.

INFO is just default, WARN is yellow, ERROR is red.

We try to automatically detect if the output is a TTY (and thus supports
colors), and don't emit colors if so. Windows 10 supports ANSI color
codes starting with a specific build, but we don't care to emit whatever
garbage Microsoft invented for builds older than that.

leo60228 0063e1c3bc Use Emscripten's main loop
On Emscripten, SDL_Delay is implemented as a busy loop. In addition,

Misa 8dc5d69ef3 Do not close game if custom level has assets issues
It's quite rude to close the game entirely if there is trouble with
assets. Instead, just unload the assets and gracefully return to the
title screen.
2021-08-10 16:33:52 -04:00
Misa 45dd7c39b7 Fix cycling title BG more than once per frame
This can happen if you select an option in a menu that (A) returns to
the previous menu and (B) saves settings. If the settings save fails,
this will create another menu on the same frame that cycles the tower BG
after it's already been cycled for that frame. Examples are the slowdown
and glitchrunner menus.

I could fix this by creating a new function that copy-pastes all of
Game::savestatsandsettings_menu() except for the map.nexttowercolour()
at the end. But that's copy-pasting code.

Instead what I've done is added a variable to signal if the color has
already been cycled this frame, so we don't cycle it again. This also
covers cases of possible double-cycling in the future as well.
2021-08-05 21:42:59 -04:00
Misa 9f603ea3fe Consolidate tower BG bypos and bscroll assignments
Tower backgrounds have a bypos and bscroll. bypos is just the y-position
of the background, and bscroll is the amount of pixels to scroll the
background by on each frame, which is used to scroll it (if it's not
being redrawn) and for linear interpolation.

For the tower background (and not the title background), bypos is
map.ypos / 2, and bscroll is (map.ypos - map.oldypos) / 2. However,
usually bscroll gets assigned at the same time bypos is incremented or
decremented, so you never see that calculation explicitly - except in
the previous commit, where I worked out the calculation because the
change in y-position isn't a known constant.

Having to do all these calculations every time introduces the
possibility of errors where you forget to do it, or you do it wrongly.
But that's not even the worst; you could cause a linear interpolation
glitch if you decide to overwrite bscroll without taking into account
map.oldypos and map.ypos.

So that's why I'm adding a function that automatically updates the tower
background, using the values of map.oldypos and map.ypos, that is used
every time map.ypos is assigned. That way, we have to write less code,
you can be sure that there's no place where we forget to do the
calculations (or at least it will be glaringly obvious) or we do it
wrongly, and it plays nicely with linear interpolation. This also
replaces every instance where the manual calculations are done with the
new function.
2021-04-30 05:31:47 -04:00
Misa 7c55b449e0 Fix two places with map.oldypos not being assigned
These places didn't assign map.oldypos when they assigned map.ypos. This

consistent and proactively fix these.

Misa ea2ecc81b1 Don't process music, fades, or timer when unfocused

Misa 27874e1dc6 Add music and sound volume config options

Misa 510ec07021 Re-fix resumemusic/musicfadein once again
So it looks like facb079b35 (PR #316) had
a few issues.

The SDL performance counter doesn't really work that well. Testing
reveals that unfocusing and focusing the game again results in
the resumemusic() script command resuming the track at the wrong time.
Even when not unfocusing the game at all, stopping a track and resuming
it resumes it at the wrong time. (Only disabling the unfocus pause fixes
this.)

Furthermore, there's also the fact that the SDL performance counter
keeps incrementing when the game is paused under GDB. So... yeah.

Instead of dealing with the SDL performance counter, I'm just going to
pause and resume the music directly (so the stopmusic() script command
just pauses the music instead). As a result, we no longer can keep
constantly calling Mix_PauseMusic() or Mix_ResumeMusic() when focused or
unfocused, so I've moved those calls to happen directly when the
relevant SDL events are received (the constant calls were originally in
VCE, and whoever added them (I'm pretty sure it was Leo) was not the
sharpest tool in the shed...).

And we are going to switch over to using our own fade system instead of
the SDL mixer fade system. In fact, we were already using our own fade
system for fadeins after collecting a trinket or a custom level
crewmate, but we were still using the mixer system for the rest. This is
an inconsistency that I am glad to correct, so we're also doing our own
fadeouts now.

There is, however, an issue with the fade system where the length it
goes for is inaccurate, because it's based on a volume-per-frame second
calculation that gets truncated. But that's an issue to fix later - at
least what I'm doing right now makes resumemusic() and musicfadein()
work better than before.

Misa f8f6f3b96e Add option to re-enable 1-frame input delay
This is an option for speedrunners whose muscle memory is precisely
trained and used to the 1-frame input delay that existed in 2.2 and
below. It is located in Game Options -> Advanced Options, and is off by
default.

To re-add the 1-frame input delay, we simply move the key.Poll() to the
start of the frame, instead of before an input function gets ran -
undoing what #535 did.

There is a frame ordering-sensitive issue here, where toggling
game.inputdelay at the wrong time could cause double-polling. However,
we only toggle it in an input function, which regardless is always
guaranteed to be ran after key.Poll() (it either happened at the start
of the frame or just before the input function got ran), so this is not
an issue. But, in case we ever need to toggle this variable in the
future, we can just use the defer callbacks system to defer the toggle
to the end of the frame - also added by #535.

Added at the request of Habeechee on the VVVVVV speedrunning Discord
server.

Misa 91bc438d79 Fix funcs not being reassigned if delta func is last func in list
One of the solutions to the quit signal unfocus pause regression is to
add a no-op delta func to the unfocused func table. However, this
results in the game being stuck in unfocus pause forever, because when
it reaches the end of a list on a delta func, it won't reassign the
active functions - only when the end of a list is a fixed func will it
do so. A workaround is to then add a no-op fixed func afterwards, but
that's inelegant.

The solution in the end to the quit signal regression is to not bother
with adding a delta func, so the game as of right now actually never has
a delta func at the end of a list, and probably never will - but this is
one piece of technical debt I don't want to leave laying around. In case
we're ever going to put a delta function at the end of a list, I've made
it so that delta functions will now reassign the list of active funcs if
they happen to be at the end of the func list.
2021-04-02 11:15:18 -04:00
Misa 03a0b1feb2 Call VVV_exit() when SDL_QUIT is received
This fixes a regression introduced by #535 where a quit signal (e.g.
Ctrl-C) sent to the window while the game was in unfocus pause wouldn't
close the game.

One problem was that key.quitProgram would only be checked when control
flow switched back to the outer loop in main(), which would only happen
when the loop order state machine switched to a delta function. As the
unfocused func table didn't have any delta functions, this means
key.quitProgram would never be checked.

So a naïve solution to this would just be to add a no-op delta func
entry to the unfocused func table. However, we then run into a separate
issue where a delta function at the end of a func list never reassigns
the active funcs, causing the game to be stuck in the unfocus pause
forever. Active func reassignment only happens after fixed funcs. So
then a naïve solution after that would be to simply add a no-op fixed
func entry after that. And indeed, that would fix the whole issue.

However, I want to do things the right way. And this does not seem like
the right way. Even putting aside the separate last-func-being-delta
issue, it mandates that every func list needs a delta function. Which
seems quite unnecessary to me.

Another solution I considered was copy-pasting the key.quitProgram check
to the inner loops, or adding some sort of signal propagation to
the inner loops - implemented by copy-pasting checks after each loop -
so we didn't need to copy-paste key.quitProgram... but that seems really
messy, too.

So, I realized that we could throw away key.quitProgram, and simply call
VVV_exit() directly when we receive an SDL_QUIT event. This fixes the
issue, this removes an unnecessary middleman variable, and it's pretty
cleanly and simply the right thing to do.

Misa 0c72260c5d Fix oversight with unfocus pause screen in Flip Mode
Flip Mode flips all the unfocus pause screen text upside-down, to make
it read in reverse order. This looks kind of strange to me, and I don't
think it was intended. So I'm flipping the text again so it's the right
way up in Flip Mode.
