This moves editorrenderfixed(), editorrender(), editorinput(),
editorlogic(), and their associated functions to a new file named
Editor.cpp - which is exactly what it says on the tin; it stores all the
functions related to the actual in-game editor loop. Also, the existing
editor.cpp has been renamed to CustomLevels.cpp.
All XML functions now check the return value of
tinyxml2::XMLDocument::Error() after each document gets loaded in to
TinyXML-2. If there's an error, then all functions return. This isn't
strictly necessary, but printing the error message that TinyXML-2 is the
bare minimum we could do to be useful.
Additionally, I've standardized the error messages of missing or
corrupted XML files.
Also, the way the game went about making the XML handles was... a bit
roundabout. There were two XML handles, one for the document and one for
the root element - although only one XML handle suffices. So I've
cleaned that up too.
I could've gone further and added error checking for a whole bunch of
things (e.g. missing elements, missing attributes), but this is good
enough.
Also, if unlock.vvv or settings.vvv don't exist yet, the game is
guaranteed to no-op instead of continuing with the function. Nothing bad
seems to happen if the function continues, but the return statements
should be there anyway to clearly indicate intent.
Enemy/platform bounds are intended to not be drawn if they cover the
whole screen, since that's what their default bounds are.
However, the code inadvertently made it so if ANY of the bounds touched
a screen edge, the bounds wouldn't be drawn. This is because the
conditionals used "and"s instead of "or"s. The proper way to write the
positive conditional is "x1 is 0 and y1 is 0 and x2 is 320 and y2 is
240", and when you invert that conditional, you need to also invert all
"and"s to be "or"s. This is not the first time that the game developers
failed to properly negate conjunctional statements...
Ever since tilesheets got expanded, custom levels could use as many
tiles as they wanted, as long as it fit under the 32-bit signed integer
limit.
Until 6c85fae339 happened and they were
reduced to 32,767 tiles.
So I'm being generous again and changing the type of the contents array
(in mapclass and editorclass) back to int. This won't affect the
existing tilemaps of the main game, they'll still stay short arrays. But
it means level makers can use 2 billion tiles once again.
This lets users place down tiles above 1199 in Direct Mode, if their
tilesheet has more than 1200 tiles.
I don't like the copy-pasted code here but it'll have to make do.
If you use Lab tilecol 6, you get the rainbow background. However, this
is unintended, because the associated autotiling is... not very good.
To combat that, Ved disallows using the Lab rainbow background outside
of Direct Mode. We will follow Ved here and only allow switching to the
rainbow background if you're in Direct Mode. Also make sure if someone
is disabling Direct Mode with the rainbow background that it gets reset
properly.
So, platv is a room property that controls the speed of custom entity
platforms in the room (unless, of course, they're created with
createentity). Problem is, this is how 2.2-and-previous coding standards
were:
ed.level[game.roomx-100+((game.roomy-100)*ed.maxwidth)]
Overly long, verbose, not entirely clear unless you already know what it
means? Copy-pasted over and over due to all of the above? Surely a
recipe for not making any coding errors!
Ironically enough, copy-pasting is basically the best approach here
(short of refactoring the whole thing, like I did in
945d5f244a), since if you don't ACTUALLY
copy-paste and just re-type it on your own, you'll end up making more
mistakes. Like what happened here:
ed.level[game.roomx-100+((game.roomy-100)*ed.mapwidth)].platv
Do you see the mistake...? Yeah, mapwidth (with a P) instead of maxwidth
(with an X). You'd have to look closely to find it.
So what does this mean for platv? Well, it means that it multiples the
y-coordinate of the room by the map width instead of the max width (20),
like every other room property. So that means if your map width is less
than 20, like say, map width 10, the platv value for (2,2) will be
stored in (2,1)'s room properties instead of (2,2)'s. Because if you go
off of map width, the room index for (2,2) is 2 + 2 * 10 = 22, but if
you go off of max width, the room index for (2,1) is 2 + 1 * 20 = 22.
Now this wouldn't be bad, except for another 2.2-and-previous
standard... kind of just not exposing things directly to the end user.
Whether that's simply not documenting something (as in the case of
ifwarp and warpdir, which by all measures were completely intended to be
used in custom levels but just simply were never known properly until I
discovered how to use them in 2019), or in this case, not giving any way
for the user to fiddle with platv from the in-game editor. Because if
there was a way to do that, and someone decided to test to see if platv
worked okay, they would discover something was up.
So... since I refactored room properties in
945d5f244a, I kind of broke platv by
fixing it. Now levels that relied on platv being the broken way don't
work.
How do I fix it, and thus break it again? Well, I'll do what I did for
scripts - handle the scrambling when reading and writing the level, and
keep things sane at least internally.
Thus: editorclass::load() will unscramble platv data in the right way,
and editorclass::save() will re-scramble platv in the right way too.
If a zip file is improperly structured, a message will be displayed when
the player loads the level list.
This will only display the last-displayed improper zip, because there
only needs to be one displayed at a time. Also because doing anything
more would most likely require heap allocation, and I don't want to do
that.
This fixes being able to re-trigger the fadeout while a fadeout is
already happening. It also fixes being able to enter playtesting during
the fadeout, which means the level now has a fadeout you normally can't
do in actual gameplay.
In the past, people have reported having glitched levels where they
can't get the trinket star or can't complete the level because the
number of trinkets or crewmates is one higher than what can be obtained
in the level.
How did this happen? Well, it turns out that if you place an entity, and
then resize the level to be smaller, that entity still exists. This is
inconsequential for most entities, but if the entity is a trinket or
crewmate, that entity is still counted towards the number of trinkets or
crewmates in the level.
One fix would be to just remove entities whenever the level is
downsized, but then if someone accidentally downsizes the level and
wants to go back, that entity will be gone. Plus, it would be
inconsistent with tiles, because tiles don't get removed when you
downsize the level. Also, it wouldn't fix existing levels where people
have managed to place trinkets or crewmates out of bounds.
So instead, ed.numtrinkets() and ed.numcrewmates() should simply ignore
trinkets and crewmates that are outside the playable area. That way,
levels with glitched trinkets and crewmates can still be completed, and
can still be completed with the trinket star.
For consistency, the Viridian squeak will now play whenever you start
editing a level description field, or finish editing it (either by
pressing Esc or Enter).
This is a lot of copy-pasted code, but a little bit of copy-pasting
never hurt anyone...
The keybind to interact with activity zones and teleporters is now
separate from the keybind to open the map, or return to the editor from
in-editor playtesting, or restart a time trial. The keybind is now E,
and the default controller bind is X. No controller button prompts, but
the game didn't have controller button prompts anyways, so whatever.
Doing this now because if people's muscle memory are going to be broken
by not being able to spam the map keybind anymore, at least we can help
a bit by changing the keybind so they can keep spamming it - their
muscle memory is going to be broken anyways.
This option has to be enabled by going to the speedrunner menu options
and selecting "interact button". It is disabled by default.
All prompt text needs to be string-interpolated every time they are
drawn, because it is possible for people to change which interact button
they use in the middle of gameplay, via the in-game options.
Closes#736.
If there were two scripts with the same name, removing one of them would
only remove the other script from the script name list, and not also
remove the contents of said script - leading to a desync in state, which
is probably bad.
Fixing this isn't as simple as removing the break statement - I either
also have to decrement the loop variable when removing the script, or
iterate backwards. I chose to iterate backwards here because it
relocates less memory than iterating forwards.
No need to use it when good ol' loops work just fine.
Iterating backwards is correct here, in case there happen to be more
than one of the item in the vectors, and also to minimize the amount of
memory that needs to be relocated.
So, the codebase was kind of undecided about who is responsible for
initializing the parameters passed to FILESYSTEM_loadFileToMemory() - is
it the caller? Is it FILESYSTEM_loadFileToMemory()? Sometimes callers
would initialize one variable but not the other, and it was always a
toss-up whether or not FILESYSTEM_loadFileToMemory() would end up
initializing everything in the end.
All of this is to say that the game dereferences an uninitialized
pointer if it can't load a sound effect. Which is bad. Now, I could
either fix that single case, or fix every case. Judging by the title of
this commit, you can infer that I decided to fix every case - fixing
every case means not just all cases that currently exist (which, as far
as I know, is only the sound effect one), but all cases that could exist
in the future.
So, FILESYSTEM_loadFileToMemory() is now guaranteed to initialize its
parameters even if the file fails to be loaded. This is better than
passing the responsibility to the caller anyway, because if the caller
initialized it, then that would be wasted work if the file succeeds
anyway because FILESYSTEM_loadFileToMemory() will overwrite it, and if
the file fails to load, well that's when the variables get initialized
anyway.
This fixes a bug where after loading in to the level editor, pressing
Esc and then switching your option to something other than the first
option, then pressing Esc again to close the menu, then pressing Esc
once more would not keep your menu option.
This is because the code that checks if Menu::ed_settings is already in
the stack doesn't account for if ed_settings is the current menu - the
current menu doesn't get put in to the stack.
In hindsight, maybe I could have designed the new menu system better so
the current menu IS on the stack, and/or should have used a
statically-allocated linked list for each menu name for the stack frames
(instead of an std::vector) and asserted if a menu that already existed
in the stack was created instead... that'll have to be done later,
though.
This fixes a bug where quitting to the menu from command-line
playtesting with -playassets specified would always use those assets
when loading back in to any custom level. This also fixes loading in to
a custom level quicksave always using the command-line playtesting
arguments instead of using the actual quicksave.
While the game does support playing levels with filenames that don't
have the .vvvvvv extension, it doesn't do it well.
Namely, those files can't be loaded or saved into the editor (because a
.vvvvvv always gets tacked on to your input when saving or loading). In
2.3, this gets worse because you can't load a level without a .vvvvvv
extension from command-line playtesting (because a .vvvvvv automatically
gets added) and you can't load per-level custom assets.
The only place where extensionless level files are supported is when
loading level metadata. But this makes it so they no longer work. This
is technically an API break, but it's easily fixed (just add the
.vvvvvv), plus there's nothing to be gained from not having an
extension, plus basically no one ever actually did this in the first
place (as far as I know, I am the only person to have ever done this,
and no one else ever has).
It is no longer possible to cause Undefined Behavior via accessing
out-of-bounds room properties.
What happens instead is - if you attempt to fetch an out-of-bounds room
property, you get a "blank" room property that just has all of the
defaults, plus its tileset is 1 because all tilesets that are nonzero
use tiles2.png, and it closely emulates the previous behavior where it
was some bogus value but definitely not zero. Its Direct Mode is also 1,
because the tiles contained within it are just mishmashed repeats of
existing tiles on the map, and we shouldn't autotile that.
The roomname also gets cleared in case the user attempts to set the room
name of an out-of-bounds room property.
If you attempt to set the property of an out-of-bounds room property,
then nothing happens.
This replaces all raw ed.level accesses with new setter and getter
funcs, which makes it easier to add bounds checks later. And I've also
removed all the manually-written bounds checks, since they will go into
the new getter and setter.
To get the room properties of a specific room, you use
editorclass::getroomprop(), which returns a pointer to the room
properties - then you just read off of that pointer. To set a room
property, you use editorclass::setroom<PROP>(), where <PROP> is the name
of the property. These are maintained using X macros to avoid
copy-pasting. editorclass::getroompropidx() is a helper function and
shouldn't be used directly.
This removes all traces of Undefined Behavior from getting and placing
tiles.
This mimics the previous behavior (2.2 and below) as reasonably as
possible. `vmult` was previously a vector, there was a bunch of unused
space directly after the end of the usable space of the vector, which
was all filled with zeroes. The same goes for `contents`, having
previously been a vector, and so having a bunch of zeroes immediately
following the end of the in-bounds space. That's why both are 0 if you
index them out of bounds.
This makes it easier to add bounds checks to all accesses of
ed.contents.
To do this, I've added editorclass::gettile(), editorclass::settile(),
and editorclass::getabstile() (with a helper function of
editorclass::gettileidx() that really shouldn't be used directly), and
replaced all raw accesses of ed.contents with those functions
appropriately.
This also makes the code more readable, as a side effect.
It is possible for any of the QueryIntAttribute()s to fail, most
commonly if the attributes don't exist. If that happens, then that part
of the temporary edentity won't be initialized, and we'll end up having
a partially-uninitialized edentity - then doing much of anything with it
will result in undefined behavior.
To fix this, just initialize the temporary edentity.
game.shouldreturntoeditor was added to fix a frame ordering issue that
was causing a bug where if you started playtesting in a room with a
horizontal/vertical warp background, and exited playtesting in a
different room that also had a horizontal/vertical warp background and
which was different, then the background of the room you exited in would
slowly scroll offscreen, when you re-entered the editor, instead of the
background consisting entirely of the actual background of the room.
Namely, the issue was that the game would render one more frame of
GAMEMODE after graphics.backgrounddrawn got set to false, and re-set it
to true, thus negating the background redraw, so the editor background
would be incorrect.
With defer callbacks, we can now just use a couple lines of code,
instead of having to add an extra kludge variable and putting handling
for it all over the code.
While working on #535, I noticed that editormenuactionpress() still
didn't do the explicit void declaration. Then I ran `rg 'void.*\(\)'`
and found three other functions that I somehow missed in #628. Whoops.
Well, now they no longer are missed.
This is a small quality-of-life tweak that makes it so if you're in the
middle of editing a level, you don't have to save the level, exit to the
menu, change whatever setting you wanted, re-enter the editor, and type
in the level name, just to change one setting. This is the same as
adding Graphic Options and Game Options to the in-game pause menu,
except for the editor, too.
To do this, I'm reusing Game::returntopausemenu() (because all of its
callers are the same callers for returning to editor settings) and
renamed it to returntoingame(), then added a variable named
ingame_editormode to Game. When we're in the options menus but still in
the editor, BOTH ingame_titlemode and ingame_editormode will be true.
This is a small quality-of-life thing that makes it so you don't have to
move your menu selection all the way over to the "return" button in
order to return to the previous menu. You can just press Escape instead
to return to the previous menu. The previous behavior of pressing Escape
was to bring up the 'confirm quit' menu, or if you were in an options
menu in-game, return to the pause menu.
If you're on the main menu (and thus don't have any previous menu) and
press Escape, the game will instead bring up the 'confirm quit' menu.
For consistency, the "quit game" option on the main menu will also bring
up the 'confirm quit' menu as well, instead of immediately closing the
game.
Pressing the controller button mapped to Escape will also work as well.
The only menus that don't have return buttons are the 'countdown' menus
- so the game will not let you press Escape if there's a menu countdown
happening.
Now that pressing Escape in the 'continue' menu will just bring you back
to the 'play' menu, there's no need to specifically put
map.nexttowercolour() first when canceling the 'confirm quit' menu.
This avoids the room name awkwardly moving back up if the cursor is at
the bottom of the screen in a room with a room name, then the user
switches to a room without a room name, then moves the cursor away from
the bottom, then switches to a named room - even though the cursor was
already away from the bottom of the screen.
Conversely, if the user moves their cursor to the bottom of the screen
in an unnamed room, then switches into a named room, the room name will
already have been hidden and they won't need to wait for it to hide.
This fixes the drawer suddenly popping up only to disappear, if the user
leaves a Direct Mode room into a non-Direct Mode room when the drawer
hasn't closed all the way, and then re-enters a Direct Mode room.
Gravity line correction no longer happens on every deltaframe. This
means less CPU time is wasted. Although, there's probably no need to
correct gravity lines on every single frame... hm... well, that's an
optimization for later (there's plenty of other stuff to cache, like
minimap drawing or editor foreground drawing).
There's no need to create an std::string for every single element just
to see if it's a key name.
At least in libstdc++, there's an optimization where std::strings that
are 16 characters or less don't allocate on the heap, and instead use
the internal 16-char buffer directly in the control structure of the
std::string. However, it's not guaranteed that all the element names
we'll get will always be 16 chars or less, and in case the std::string
does end up allocating on the heap, we have no reason for it to allocate
on the heap; so we should just convert these string comparisons to C
strings instead.
