This infinite loop would occur because once you pressed left or right,
the game keeps searching through all the list of teleporters until it
finds one that is unlocked. But if there's none that are unlocked, then
the game goes into an infinite loop, which brings up the Not Responding
dialog on Windows so you can kill it.
Normally, you're not supposed to have no teleporters unlocked while
being able to access a teleporter, but you can achieve this by going to
Class Dismissed from a custom level (while making sure you don't start
in 0,0, because there's a teleporter there that you would unlock).
The solution is to make sure at least one teleporter is unlocked before
doing any searching.
A do-while is just a while-loop, but the inner block will always run
once before the conditional is checked.
It looks like in order to achieve this desired behavior (always run the
block once before checking the conditional), instead of using a do-while
loop, Terry just used a normal while-loop and copy-pasted the inner
block on the outside.
So I'm de-duplicating the code.
The problem we're running into is entirely contained in the Screen - we need to
either decouple graphics context init from Screen::init or we need to take out
the screenbuffer interaction from loadstats (which I'm more in favor of since we
can just pull the config values and pass them to Screen::init later).
The options for fullscreen and scaling mode were at the top, then there
were various other graphical options, and then the option to resize to
the nearest window size that is of an integer multiple was all the way
below that. Now that last option is moved to be right below the other
options related to window sizing.
VVVVVV's menus are kind of packed to the brim, so I thought it was time
to recategorize the menus a little bit. There's now a new "advanced
options" menu which holds the following options which were moved out of
graphic options, game options and especially accessibility options:
- toggle mouse
- unfocus pause
- fake load screen
- room name background
- glitchrunner mode
I also made the positioning of the titles and descriptions more
consistent, and made some options which were moved to the new menu not
so abbreviated ("load screen" and "room name bg")
Flip Mode will now be in the game options menu if either:
(1) You're playing the M&P version.
(2) You have it unlocked and you came here from the in-game pause
screen.
This is because if you're playing M&P, you'd have to close the game,
edit unlock.vvv, and re-launch the game to toggle Flip Mode, since
there's no other way to do so. And if you're playing the full version,
you'd have to save and exit your session in order to toggle Flip Mode.
If you want your game window to simply be exactly 320x240, or 640x480,
or 960x720 etc. then it's really annoying that there's no easy way to do
this (to clarify, this is different from integer mode, which controls
the size of the game INSIDE the window). The easiest way would be having
to close the game, go into unlock.vvv, and edit the window size
manually. VCE has a 1x/2x/3x/4x graphics option to solve this, although
it does not account for actual monitor size (those 1x/2x/3x/4x modes are
all you get, whether or not you have a monitor too small for some of
them or too big for any of them to be what you want).
I discussed this with flibit, and he said that VCE's approach (if it
accounted for monitor size) wouldn't work on high-retina displays or
high DPIs, because getting the actual multiplier to account for those
monitors is kind of a pain. So the next best thing would be to add an
option that resizes to the nearest perfect multiple of 320x240. That way
you could simply resize the window and let the game correct any
imperfect dimensions automatically.
It's sometimes unwanted by people, and it's unwanted enough that there
exist instructions to hexedit the binary to remove it (
https://distractionware.com/forum/index.php?topic=3247.0 ).
Fun fact, the unfocus pause didn't exist in 2.0.
This was fixed in 2.3 because one of the side effects of this janky
system was being able to accidentally immediately quit to the title if
the screen was black during a cutscene, which is something very likely
to happen to casual players.
Anyway, credits warp uses this gamestate-based system because it
utilizes quitting to the title screen doing gamestate 80. From there,
you increment the gamestate to gamestate 94 to use the Space Station 2
expo script.
This is the first part of what is necessary for credits warp to work.
If the "- Press ACTION to advance text -" prompt is up, and you manage
to keep it up, then you can indefinitely increment the gamestate by
pressing ACTION.
This is first used in credits warp to teleport to the start of Space
Station 2 (by utilizing the Eurogame expo script, triggered by a
gamestate), and then again later by using a teleporter that has a high
gamestate number to increment to the [C[C[C[C[Captain!] cutscene.
Glitchrunner mode is intended to re-enable glitches that existed in
older versions of VVVVVV. These glitches were removed because they could
legitimately affect a casual player's experience. Glitches like various
R-pressing screwery, Space Station 1 skip, telejumping, Gravitron
out-of-bounds, etc. will not be patched.
This fixes a corner case where using gamestate 82 from the editor would
put you in a softlock because it would return to the editor settings
menu, which only functions in EDITORMODE and results in a softlock in
TITLEMODE.
This is already done for invincibility. It's kind of unnecessary, but
it's just to make sure if for some reason in the future variables like
insecretlab/intimetrial/nodeathmode don't get reset when exiting to the
menu.
Another thing that's annoyed me a lot is being unable to simply press
Esc to close the pause menu. You'd have to hover over the "return to
game" or "keep playing" option. This would be even more annoying with
more options on the menu, so allowing to press Esc is a nice
quality-of-life thing.
Otherwise you could keep re-pressing ACTION on the "yes" option and keep
stalling it until it finally faded out, or quickly go back past menu
options or something.
Otherwise the menu background would have this rendering glitch where the
bypos of the in-game tower wouldn't divide easily and have a bunch of
jitters in an otherwise smooth but overall still somewhat smooth
background.
Also set map.tdrawback to true when leaving the menu.
This is to fix the interpolated color of the tower background
persisting, as well as making sure the menu background doesn't persist
when exiting.
This would be fine, under the assumption that you could never reach the
menu from outside the menu. Well, now you can, so now this has to play
the correct song instead of track 6.
This is to pre-emptively prevent piling up stack frames for what I'll be
adding next, which is pressing Esc in the options menu in-game
automatically moving you back to MAPMODE.
Since the exact same tower background is also used on the menu, we need
to save the current state of the background when entering the menu
(before overwriting it), and then put it back when we're done. Maybe we
ought to separate the in-game and menu tower backgrounds...
This also fixes a semi-hilarious bug where you could make Panic Room go
in the other direction by simply going to the options menu in-game.
This is accomplished by adding convenience functions
mapclass::bg_to_kludge() and mapclass::kludge_to_bg().
Well this is a bit annoying. I can call graphics.updatetowerbackground()
just fine, but I have to get at the title color update routine inside
titlelogic(), which is hard-baked in. So I have to pull that code
outside of the function, export it in the header, and then call it when
I transition to TITLEMODE.
So now the options do what they do. However, I still need to fix the
1-frame glitch when switching to TITLEMODE, as well as make returning
from the menu return back to MAPMODE, as well as making this better menu
integrate seamlessly with the existing menus.
This prevents from having to repeat 'if (game.menupage == ...)'
everywhere, which makes for more concise code.
I know you're technically supposed to indent the cases surrounded by
if-guards, but I don't think indenting them here would help anything.
I'd only indent it if the 'if' had an 'else', for example. But if it
surrounds the whole case, then there's no need for indentation.
There is now an option in "graphic options" named "toggle fps", which
toggles whether the game visually runs at 1000/34 FPS or over 1000/34
FPS. It is off by default.
I've had to put the entire game loop in yet another set of braces, I'll
indent it next commit.
When you pressed and released ACTION to speed up the credits, the
credits position would end up being 1 frame off from the background.
This is due to the fact that we update the tower background after we
update the credits position, so this commit moves the tower background
update before the credits position update.
Now it's really, really smooth. Except for like the last frame when it
goes down, which I sometimes didn't notice (but maybe it didn't happen
every time due to being lucky on the delta timesteps or something,
whatevs.)
obj.getplayer() can return -1, which can cause out-of-bounds indexing of
obj.entities, which is really bad. This was by far the most changes, as
obj.getplayer() is the most used entity-getting function that returns
-1, as well as the most-used function whose sentinel value goes
unchecked.
To deal with the usage of obj.getplayer() in mapclass::warpto(), I just
added general bounds checks inside that function instead of changing all
the callers.
This removes the TinyXML source files, removes it from CMakeLists.txt,
removes all the includes, and removes the functions
FILESYSTEM_saveTiXmlDocument() and FILESYSTEM_loadTiXmlDocument() (use
FILESYSTEM_saveTiXml2Document() and FILESYSTEM_loadTiXml2Document()
instead).
Additionally I've cleaned up the tinyxml2.h include in FileSystemUtils.h
so that it doesn't actually include tinyxml2.h unnecessarily, meaning a
change to TinyXML2 shouldn't rebuild all files that include
FileSystemUtils.h.
Seems a bit wasteful to do the whole "parse the XML document thing"
instead of a simple file check. It doesn't even fail if the XML document
is invalid, but whatever.
