This fixes an oddity that's only visual, which could only happen in
custom levels by using the createentity() internal command.
For the same reason that the second through fourth tiles of moving
platforms on the top and left was buggily rendered, SDL_BlitSurface()
strikes again to mutate the SDL_Rect we pass it and render the next
SDL_BlitSurface() call inbounds, even though we don't need it to.
Previously, the game could end up rendering a warping sprite twice due
to the fact that it could run "if entity is on the right side of the
screen" right after "if entity is on the left side of the screen" (but
not the other way around). This is most noticeable if you have a custom
player sprite with translucent pixels and stand on the left side of a
warping screen, but the code suggests it happens when warping through
the top of the screen, too.
Instead of doing
if (!obj.entities[i].invis)
{
...
}
It's better to do
if (obj.entities[i].invis)
{
continue;
}
...
It reduces the indentation by one level, which is always a good thing.
In the last commit, I removed having the flip mode conditional directly
inside the sprite-drawing code for each size type, which would reduce
the indentation one level. However, I opted to hold off un-indenting
until this commit, otherwise it would've produced too much noise.
The game uses flipsprites.png instead of sprites.png when in flip mode,
mostly to add exceptions for sprites that SHOULDN'T be flipped in flip
mode.
Looks like to achieve this, the routines for sprite drawing got
copy-and-pasted every single time flipsprites.png needed to be
conditionally used, resulting in large amounts of copy-pasted code. And
this copy-pasted code resulted in copy-paste errors, with relating to
VVVVVV-Man, because apparently due to two copy-pasting errors, the
combined giant crewmate in the epilogue uses flipsprites.png even if you
aren't in flip mode, and it also uses the width instead of the height of
sprites_rect when in flip mode (although, this doesn't end up mattering,
but still).
The solution here is to simply change the referenced sprites vector to a
pointer that can conditionally change based on the game being in flip
mode or not.
Looks like I forgot to test that my music silencing patch didn't break
the music being silent during the "You have found a shiny trinket" and
"You have found a shiny crewmate" text boxes. So I've added a check for
game.completestop in the music handling in main.cpp.
Found this bug while I was testing my towerlogic/gamelogic merge patch.
The problem here is that we're directly using the C stdio library,
instead of using PHYSFS's stuff. So I've added a function
FILESYSTEM_delete() that does exactly that.
This commit fixes a slightly frustrating thing where if you start a new
game, and then exit before saving, "start game" will always take you to
a new game, even though you have unlocked things like the Secret Lab or
Time Trials.
Now, if you select "new game" (only possible if you have something
unlocked), then quit before saving, "start game" will still take you to
the play menu, but "continue" is replaced with "start" and "new game" is
gone.
This will be a useful shorthand to ask "do we have the Secret Lab, or
any Time Trial, or Intermission replays, or No Death Mode, or Flip Mode
unlocked?"
This fixes being able to rack up a large amount of stack frames by
pressing Esc repeatedly in the editor, which would be a problem if you
were to then return to the main menu afterwards.
Instead, if Menu::ed_settings is already in the stack, the game will
simply return to that menu instead of creating it. Else, it will just
create the menu.
Also, as extra attention to detail, I made sure that the menu create or
return only happens if Esc opens the settings menu, and not when Esc is
closes it.
This stabilizes the code that handles the menu that you land on if you
press Esc and quit to the menu.
Instead of using Game::returnmenu(), we now use the new function
Game::returntomenu() to clearly express intent that we want to return to
a specific menu. So I've added another kludge variable
Game::wasinintermission for the was-in-intermission case.
Also, I made it so that if you didn't have a main game telesave or
quicksave, you just get brought back to the main menu. Because you
shouldn't be able to go to the play menu without a quicksave or
telesave.
When exiting from a game-gamestate which may have been entered through a
varying amount of menus, the solution is to not use Game::returnmenu(),
and to instead have a way to go back to a certain given menu.
This commit fixes a bug where the second, third, and fourth tiles of
moving platforms would render offset from the first tile if the moving
platform hit the top or left edge of the screen.
This is due to the fact that SDL_BlitSurface() will end up changing the
coordinates of the rectangle we pass to it to be 0 if they're negative,
but only after it's already been drawn. Previously, we kept re-using the
same rectangle each time we drew each segment of the moving platform,
but since it only changes the draw rectangle after it's already been
drawn, the first tile shows up fine, but not the rest of the tiles,
hence resulting in an offset.
To fix this, we do the same thing as we did for drawing the "really big
sprite" (size-type 9): just reset the rectangle we use every time we
draw a segment of the moving platform.
They're literally the exact same thing, except one is 4 and the other
has an 8. No need to have all that copy-pasted code.
Actually, the only other difference was that size-type 8 set the
drawRect to sprites_rect instead of tiles_rect for some reason? Even
though it doesn't matter, anyway, because SDL_BlitSurface() only cares
about the X and Y you pass it, not the width and height, which is the
only difference between tiles_rect and sprites_rect.
To make sure that people wouldn't wonder where size-type 8 went if they
saw a blank space between size-type 7 and size-type 9, I kept the
size-type 8 conditional, but inside it is just a comment telling you to
go to size-type 2.
Instead of copy-pasting all the BlitSurfaceStandard()s all over again,
just make the referenced vector a pointer that changes depending on
map.custommode.
There's a noticeable seam in the horizontal and warp backgrounds
whenever you enter a new room. Entering a new room triggers the game to
re-draw the entire warp background instead of simply scrolling what it
already has. This seam is the result of the initial background draw
being misaligned with the rest of the scrolling.
If you get out your measuring tools, you'll see that it's misaligned by
exactly 3 pixels (this applies to both horizontal and vertical warping).
If you look at the part of the code where the game draws fresh warping
textures after scrolling the existing ones offscreen, you'll see it
starts with an offset of 317, which is exactly 320 minus 3. And for
vertical, it uses 237, which is exactly 240 minus 3.
This is where the misalignment comes from. Since the incoming textures
are drawn 3 pixels to the left, but the initial draw isn't, this results
in a misalignment and causes the seam.
To fix this, draw the initial draw of the horizontal and vertical warp
backgrounds 3 pixels to the left.
It looks like one bracket got out-of-place for whatever reason. This
doesn't affect the case-switch at all, due to how case-switches work,
but it's still weird to look at.
Indentation has been updated accordingly.
Some custom levels have their own custom music and sync that music to
scripted cutscenes, which is actually pretty impressive. However,
they've always run into a small thorn, which is that you can easily
desync the music by unfocusing the game, because the audio will keep
playing when the game is unfocused.
This should remove that thorn by pausing the audio on unfocus, and
resuming when focused, so that the music can no longer desync, but you
can still pause the game by unfocusing it.
This is yet another feature in VCE that hasn't been upstreamed until
now.
It looks like this variable was originally intended to keep track of th
volume of the game, but then it was used as a boolean in main.cpp to
make sure the game didn't call Mix_Volume() and Mix_VolumeMusic() every
frame.
However, it is now a problem, because I put the music mute handling code
in the very branch that game.globalsound protects against, but since
game.globalsound is here, if I mute the music, then mute the whole game,
then unmute the music, and then unmute the whole game, sound effects
will no longer be muted but the music will still be muted, until I mute
and unmute the whole game again. This is annoying and inconsistent, so
I'm removing this check from the 'if (!game.muted)' branch.
Plus, given that the Mix_VolumeMusic() and Mix_Volume() calls happen
every frame if the game is muted anyways, it doesn't seem to be a
problem to call these every frame.
These do basically nothing. The only time they're used is
getGlobalSound() in an if-statement in main.cpp, but all that
if-conditional does is call setGlobalSound() anyway, which is something
that doesn't really have any side effects. So I'm removing these vars to
simplify the code.
This is for people who want to use their own soundtrack while playing
the game, but who don't want to mute the sound effects as well.
This feature was added to VCE, but it was added in the strangest way. It
was made an option in "game options" instead of being a keybind, and I
don't know why.
The environment variable SteamTenfoot corresponds with the game running
in Steam Big Picture mode or SteamOS if it is defined. There's a
certification process for both full controller support and Big Picture
mode, and being able to launch a file window in Big Picture mode is an
instant cert failure.
Have to add some includes and put these behind some ifdefs, of course.
I'm pretty sure FreeBSD and OpenBSD and Haiku are POSIX enough that the
"open" command will work on them, too.
I would've loved to make FILESYSTEM_openDirectoryEnabled a simple bool
instead of a function, but I ran into issues with putting it in the
FileSystemUtils header file, so I'll just make it a function and call it
a day.
This fixes a bug where levels in the levels list duplicate if there's an
invalid file (such as a folder) in the levels directory.
It looks like it happens because we don't free the memory if
PHYSFS_readBytes() encounters an error, even though we should. Then we
get into Undefined Behavior territory and end up reusing memory, and
here it just happens that previously, parsing the entire XML document
for each level file was enough to make the loaded file pointer point to
garbage that would fail the metadata check, but if we optimize it so we
don't parse the entire XML document, it starts reusing memory instead.
To find each individual tag quickly, to optimize levels list loading.
I opted to not read the tags <Created>, <Modified>, and <Modifiers> as
they're actually pretty useless.
Also I've added a tag finder for <MetaData> but it's not meant to be
used directly, it's only used to check that the tag exists.
This turns the implicit-fallthrough warning into a full compile-time
error.
Implicit fallthrough is when you forget a break statement in a
case-switch, thus letting one case fall through into the next case and
causing debugging headaches.
This is different from the good type of fallthrough that you use to have
one case with multiple different names, like so:
case 0:
case 1:
case 2:
In that case, it's obvious that you want to have fallthrough there.
The problem was, if you were in a time trial and quit, it wouldn't go
back to selecting your current time trial. But also if you were in a
custom level and quit, you would still be on the playerworlds menu.
The problem was twofold: first, I simply wasn't doing the custommode
check. But secondly, I couldn't use map.custommode directly, because
whenever you quit the game aggressively hardreset()s everything
immediately when you press ACTION.
There's probably a good reason for that aggressive hardreset(), so I
won't touch that hardreset() in any way. Instead, I had to introduce two
kludge variables wasintimetrial and wasincustommode to Game, and use
those to do the check proper.
