musicclass::init() re-initializes every attribute of musicclass
unnecessarily, when initialization should be put in a constructor
instead. This is bad, because music.init() gets called whenever we enter
and exit a custom level that has assets.
Otherwise, this would result in a bug where music.usingmmmmmm would be
reset, causing you to revert to PPPPPP on the title screen whenever you
enter a level with MMMMMM selected and exit it.
This also causes a confusing desync between game.usingmmmmmm and
music.usingmmmmmm since the values of the two variables are now
different (these duplicate variables should probably be removed, too,
and a lot of other duplicate variables like these exist, too, which are
a real headache). Which means despite MMMMMM playing on the title
screen, exiting the game and re-launching it will play PPPPPP instead.
What's even more is that going to game options and switching to PPPPPP
will play PPPPPP, but afterwards launching and re-entering will play
MMMMMM. Again, having duplicate variables is very bad, and should
probably be fixed, but that's a separate patch.
...you die and the platform's x-coordinate is to the left of x=152.
Which means if you die and the platform isn't completely clear of the
space of its adjacent disappearing platform.
The block needs to be updated accordingly with calls to
obj.nocollisionat() and obj.moveblockto(), else the block will simply be
left behind and the platform will no longer have any collision. This is
in contrast to 2.2 behavior, where the platform would simply
unconditionally create a new block, which would actually end up with a
duplicate block since the previous block didn't get cleaned up, but this
didn't cause any problems because the room was carefully designed so you
would never be able to touch that previous block after you died and
respawned at the checkpoint. But it's still there.
I also added comments to document what this kludge code did, because
otherwise it would be mysterious to readers who are unfamiliar with it.
Fixes#543.
What's the difference between a slash sign and a percent sign? Well, a
percent sign is just a slash sign with two extra oranges in between, but
those two oranges make a huuuuge difference...
I can't really make the filter update only every timestep, because it's
per-pixel and operates on deltaframes too, so it TECHNICALLY runs faster
in over-30-FPS mode than not. That said, it's not really noticeable, the
filter doesn't look bad for updating more often or anything. However, I
can at least interpolate the scrolling, so it's smooth in over-30-FPS
mode.
Originally this function was made because it needed to be exported to
gameinput(), but this piece of code is actually also used in
gamecompletelogic(). So it's good to de-duplicate it here, too.
Assigning these variables is now wholly unnecessary ever since #522 got
merged, and in fact setting graphics.backgrounddrawn to false actually
causes the warp background to "skip" when the map screen gets closed. So
this fixes that bug, too.
This kludge variable was used to re-set the warp background after coming
back from the in-game settings menus. But since #522 got merged, this
has no longer been necessary.
This check is clearly meant for destroying the factory clouds in the
room "Level Complete!" in the main game, but it covers all rooms on row
8, instead of only (13,8). Adding an x-room check restricts this
behavior to only (13,8).
Trinket9 reported that this weird behavior of destroying specifically
above y-position 60 was undesirable, since they were creating an enemy
with this `behave` in a room on row 8 and it kept disappearing
instantly.
First, the variable has been inverted, because it's bad practice to have
booleans with negative names. Secondly, instead of magically setting a
signaling variable when calling fadeout(), fadeout() now has a parameter
to set the quick_fade attribute, which is much cleaner than doing the
magical assignment that could potentially look unrelated.
fadeoutqueuesong basically does the same thing as nicechange - they both
queue a song to be played when the current track is done fading out.
Except, for some reason, I decided to add fadeoutqueuesong instead of
using the existing nicechange/nicefade system.
This has consequences where fadeoutqueuesong would step on the toes of
nicechange. In the case of #390, nicechange would say "let's play
Potential for Anything" when entering the Super Gravitron, but
fadeoutqueuesong had previously said "let's play Pipe Dream" because of
the player having just exited the Super Gravitron. fadeoutqueuesong took
priority because it came first in musicclass::processfade(), and when it
called play(), the Mix_PlayingMusic() in the nicechange check afterwards
would say music would already be playing at that point, so the
nicechange wouldn't take effect.
In the end, the solution is to just merge the new system into the
already-existing system.
Fixes#390.
Just looked over this and had to do a double-take. It should be
num_mmmmmm_tracks, not num_pppppp_tracks, because MMMMMM comes first in
the vector of music tracks.
Here's what causes #401: After the fade to menu delay ticks down to 0,
the game calls game.quittomenu(), but the rest of mapinput() still
executes. This means that the block that detects your ACTION press gets
executed, because there's a check that fadetomenudelay is less than or
equal to 0, and, well, it is.
So if you've pressed ACTION on the exact frame that it counts down to 0,
then the game detects your ACTION press, then processes it accordingly,
and then sets the fadetomenudelay, which means it'll get reactivated the
next time you open the map screen. But at this point, you get sent to
TITLEMODE, because game.quittomenu() set game.gamestate accordingly.
(This is why resetting game.fadetomenu or game.fadetomenudelay in
game.quittomenu() or script.hardreset() won't fix this bug.)
The solution here is to add a game.fadetomenu check to the ACTION press
processing.
Same-frame state transition logic is hard... actually, any sort of thing
where two things happen on the same frame is really annoying.
This also applies to fadetolab and fadetolabdelay, too.
Fixes#401.
The game previously did this dumb thing where it lumped in all its
settings with its file that tracked your records and unlocks,
`unlock.vvv`. It wasn't really an issue, until 2.3 came along and added
a few settings, suddenly making a problem where 2.3 settings would be
reset by chance if you decided to touch 2.2.
The solution to this is to move all settings to a new file,
`settings.vvv`. However, for compatibility with 2.2, settings will still
be written to `unlock.vvv`.
The game will prioritize reading from `settings.vvv` instead of
`unlock.vvv`, so if there's a setting that's missing from `unlock.vvv`,
no worries there. But if `settings.vvv` is missing, then it'll read
settings from `unlock.vvv`. As well, if `unlock.vvv` is missing, then
`settings.vvv` will be read from instead (I explicitly tested for this,
and found that I had to write special code to handle this case,
otherwise the game would overwrite the existing `settings.vvv` before
reading from it; kids, make sure to always test your code!).
Closes#373 fully.
This fixes a deltaframe glitch where the "- Press ENTER to Teleport -"
prompt would show up for a split second if you exited the game while the
prompt was fully faded in, and then re-entered it.
cppcheck said: "Logical disjunction always evaluates to true".
Yes. Yes it does. Whoops. I learned how to specify ranges like this in
high school math and still screw it up...
In C++, when you have two variables in different scopes with the same
name, the inner scope wins. Except you have to be really careful because
sometimes they're not (#507). So it's better to just always have unique
variable names and make sure to never clash a name with a variable in an
outer scope - after all, the C++ compiler and standard might be fine
with it, but that doesn't mean humans can't make mistakes reading or
writing it.
Usually I just renamed the inner variables, but for tx/ty in editor.cpp,
I just got rid of the ridiculous overcomplicated modulo calculations and
replaced them with actual simple modulo calculations, because the
existing ones were just ridiculous. Actually, somebody ought to find
every instance of the overcomplicated modulos and replace them with the
actual good ones, because it's really stupid, quite frankly...
Whenever you delete all your save data, your settings aren't changed at
all, and you could resave them if you fiddled with a setting somewhere.
But the full game doesn't count Flip Mode as a setting, instead it
counts it as an unlock. This means deleting your save data would unset
Flip Mode in M&P, which would seem weird because in M&P it's just a
simple setting.
For consistency, Flip Mode shouldn't be unset when deleting save data in
M&P.
This commit fixes a bug that also sometimes occurred in 2.2, where the
teleporter sprite would randomly turn into a solid color and just be a
solid circle with no detail.
Why did this happen? The short answer is an incorrect lower bound when
clamping the teleporter sprite index in `Graphics::drawtele()`. The long
answer is bad RNG with the teleporter animation code. This commit fixes
the short answer, because I do not want to mess with the long answer.
So, here is what would happen: the teleporter's `tile` would be 6. The
teleporter code decrements its `framedelay` each frame. Then when it
reached a `framedelay` of 0, it would call `fRandom()` and essentially
ask for a random number between 0 and 6. If the RNG ended up being
greater than or equal to 4, then it would set its `walkingframe` to -5.
At the end of the routine, the teleporter's `drawframe` ends up being
its `tile` plus its `walkingframe`. So having a `walkingframe` of -5
here is fine, because its `tile` is 6.
Until it isn't. When its `tile` becomes 2, it still keeps its
`walkingframe` around. The code that runs when its `tile` is 2 does have
the possibility of completely resetting its `walkingframe` to be in
bounds (in bounds after its `tile` is added), but that only runs when
its `framedelay` is 0, and in the meantime it'll just use the previous
`walkingframe`.
So you could have a `walkingframe` of -5, plus a `tile` of 2, which
produces a `drawframe` of -3. Then `Graphics::drawtele()` will clamp
that to 0, which just means it'll draw the teleporter backing, and the
teleporter backing is a simple solid color, so the teleporter will end
up being completely and fully solid.
To fix this, I just made `Graphics::drawtele()` clamp to 1 on the lower
bound, instead of 0. So if it ever gets passed a negative teleporter
index, it'll just draw the normal teleporter sprite instead, which is
better.
This fixes the draw order by drawing all other entities first, before
then drawing all humanoids[1] after, including the player afterwards.
This is actually a regression fix from #191. When I was testing this, I
was thinking about where get a crewmate in front of another entity in
the main game, other than the checkpoints in Intermission 1. And then I
thought about the teleporters, because I remember the pre-Deep Space
cutscene in Dimension Open looking funny because Vita ended up being
behind the teleporter. (Actually, a lot of the cutscenes of Dimension
Open look funny because of crewmates standing behind terminals.)
So then I tried to get crewmates in front of teleporters. It actually
turns out that you can't do it for most of them... except for Verdigris.
And then that's what I realized why there was an oddity in WarpClass.cpp
when I was removing the `active` system from the game - for some reason,
the game put a hole in `obj.entities` between the teleporter and the
player when loading the room Murdering Twinmaker. In a violation of
Chesterton's Fence (the principle that you should understand something
before removing it), I shrugged it off and decided "there's no way to
support having holes with my new system, and having holes is probably
bad anyway, so I'm going to remove this and move on". The fact that
there wasn't any comments clarifying the mysterious code didn't help
(but, this *was* 2.2 code after all; have you *seen* 2.2 code?!).
And it turns out that this maneuver was done so Verdigris would fill
that hole when he got created, and Verdigris being first before the
teleporter would mean he would be drawn in front of the teleporter,
instead of being behind it. So ever since
b1b1474b7b got merged, there has actually
been a regression from 2.2 where Verdigris got drawn behind the
teleporter in Murdering Twinmaker, instead of properly being in front of
it like in 2.2 and previous.
This patch fixes that regression, but it actually properly fixes it
instead of hacking around with the `active` system.
Closes#426.
[1]: I'm going to go on a rant here, so hear me out. It's not explicitly
stated that the characters in VVVVVV are human. So, given this
information, what do we call them? Well, the VVVVVV community (at least
the custom levels one, I don't think the speedrunning community does
this or is preoccupied with lore in the first place) decided to call
them "villis", because of the roomname "The Villi People" - which is
only one blunder in a series of awful headcanons based off of the
assumption that the intent of Bennett Foddy (who named the roomnames)
was to decree some sort of lore to the game. Another one being
"Verdigris can't flip" because of "Green Dudes Can't Flip". Then an OC
(original character) got named based off of "The Voon Show" too. And so
on and so forth.
"Humanoid" is just a word for "crewmate or player" but without having to
say "crewmate or player". This is just to make it so humanoids get drawn
after all other entities get drawn, meaning humanoids will be drawn on
top.
I'm going to refactor drawing an entity out to a separate function, and
since I'm going to do that, I might as well make some things const to
clarify intent first and foremost and possibly improve performance or
compiler optimization.
My previous custom level forwards compatibility would only work if you
saved to the same filename as you read from. But what if you saved to a
new filename? Well, your extra XML is lost.
Not to worry, I've introduced a variable that remembers the filepath of
the currently-loaded level (the existing `filename` attribute is kind of
weird and not really suited for this purpose, so). I tried to make it a
simple `const char*`, but it turns out that's bad when you take the
`c_str()` of an `std::string` that then gets destroyed, so it's best to
use `std::string` in an `std::string` world.
So now when you save a level, it'll attempt to open the original file,
and if that doesn't exist then your extra XML gets lost anyway, but I
shouldn't be expected to keep your XML if you delete the original file.
Custom level files now have forwards compatibility - except that some
XML objects will simply discard contents and attributes they don't see
fit. For instance, edentities and level properties will not preserve
newer attributes or contents.
This is because preserving them would require having to track the XML
object as part of the edentity internally, because the edentity might
change places or even be deleted throughout the course of editing
someone's level.
I opted to not add support for preserving objects like these, because
frankly, the put-everything-in-one-file level format was and still is a
terrible idea, and we should probably switch to a new format in the
future that isn't single-file. So when that happens, there won't be a
need to preserve XML attributes on edentities.
When I encountered this function, I asked myself, why make a dedicated
function instead of casting to int?
Well, as it turns out, you can't just cast to int, because you have to
convert it to a string by doing help.String(number).c_str(), like all
the other ints. So it's actually more wasteful to do it the normal way
instead of using BoolToString().
That is, until my recent changes came along and made it so that you can
just provide an int and it'll automatically be converted to a string, no
questions asked. Now, it's more optimal to do a straight cast to int
instead of having to go through a middleman function. So this function
is getting axed in favor of casting to int instead.
This file is probably the biggest one, as there will be more settings
added in the future and we don't want people's settings to be erased. Of
course, this file will be migrated to a settings.vvv sometime later in
2.3 in order to prevent 2.2 from erasing 2.3 settings.
These XML functions will be useful for de-duplicating copy-pasted XML
handling code, while also making it so elements will get updated in
place instead of being thrown out and starting from scratch every time a
file is saved.
Now that tower, title, and horizontal/veritcal warp backgrounds all use
separate buffers, there's no longer any need to temporarily store
variables as a workaround for the buffers stepping on each other.
Instead of using the same tower buffer that gets used for towers, use a
separate buffer instead so there's no risk of stepping on the tower
buffer's toes at the wrong point in time.
This commit combined with the previous one fixes#369.
With the previous commit in place, we can now simply move some usages of
the previous towerbg to use a separate object instead. That way, we
don't have to mess with a monolithic state, or some better way to phrase
what I just said, and we instead have two separate objects that can
coexist side-by-side.
Previously, the tower background was controlled by a disparate set of
attributes on Graphics and mapclass, and wasn't really encapsulated. (If
that's what that word means, I don't particularly care about
object-oriented lingo.) But now, all relevant things that a tower
background has has been put into a TowerBG struct, so it will be easy to
make multiple copies without having to duplicate the code that handles
it.
Yet another set of temporary variables is on a global class when they
shouldn't be. These two are only used in tower background functions and
are never used anywhere else, so they're clearly temporaries.
