It's very easy to make mistakes in VVVVVV's built-in level editor, with
no way to undo them. This commit adds an undo and redo system, bound to
CTRL+Z for undo and CTRL+Y for redo. The undo and redo stacks don't
have any limits, but could easily happen in the future. VVVVVV's data
is small enough where this should never be an issue, however.
No notes show up for undoing and redoing, because keeping track of what
specific action you're doing may bloat the system, and would get
annoying for the end-user. Notes are a bit annoying in general, even.
This is so they will be updated when switching language with CTRL+F8.
Most of the editor notes are simple text that don't use any string
formatting. For the ones that aren't, some (saving and loading, changing
map size) reference variables that wouldn't change without initiating a
new note anyway. For the others, i.e. the ones that _do_ reference
variables that could easily be changed (tileset name, speed) by
switching the current room, we cache their values and use the cached
values when drawing the note. Unfortunately, this requires adding a
couple of ugly attributes to editorclass, but it'll be fine.
If you had a pink space station background, and switched to a different
tileset, some solid tiles would be placed instead. This commit fixes
that by transforming the room into the basic autotiling tiles before
changing the tileset itself. The reason why I chose this solution is
because it will help with a future change, being unhardcoding warp zone
backgrounds (which'll help with custom autotiling, if that becomes a
thing.)
This commit removes the `NO_EDITOR` and `NO_CUSTOM_LEVELS` defines,
which cleans up the code a lot, and they weren't really needed anyways.
This commit also disables the editor on the Steam Deck, and adds a
program argument to re-enable the editor, `-enable-editor`.
Autotiling was a mess of functions and if chains and switch statements.
This commit makes autotiling better by assigning each direction to one
bit in a byte, giving each different combination its own value. This
value is then fed into a lookup table to give fine control on which
tiles get placed where.
The lab tileset can now use the single tiles which were before unused
in the autotiler, and the warp zone's background tool now places the
fill used in the main game.
VED has a fill bucket subtool for tiles and backgrounds, which is
really useful when creating rooms. This commit adds a fill bucket as
well, with an adaptive tool highlight, unlike VED.
This makes it so that `CustomEntity`s, at least internally, do not use
global tile position. Instead, they will use room-x and room-y
coordinates, which will be separate from their x- and y- positions.
This makes it much easier to deal with `CustomEntity`s, because you
don't have to divide and modulo everywhere to use them.
Since editorclass::add_entity and editorclass::get_entity_at expect
global tile position in their arguments, I've added room-x and room-y
arguments to these functions too.
Of course, due to compatibility reasons, the XML files will still have
to use global tile position. For the same reason, warp token
destinations are still using global tile position too.
This uses DDA (https://w.wiki/6RSQ) to draw a line between the previous
frame's mouse position, and the current frame's mouse position. This
means that there will no longer be gaps in lines of tiles if you move
your mouse fast enough (which is actually rather slow, so it gets
annoying quickly).
The editor's timestep is no longer hardcoded to 24, as I assume that
was only done so there would be less gaps in lines of tiles drawn.
With interpolation, that is no longer an issue, so I've removed the
editor's special case for the timestep.
Scripts used a weird "hook" system, where script names were extracted
into their own list. This was completely unneeded, so it has been
replaced with using the script.customscripts vector directly.
The script editor has been cleaned up, so the cursor's Y position is
relative to the entire script, rather than what's just displaying on
the screen currently. This simplifies a lot of code, and I don't know
why it was done the other way in the first place.
The script selector and script editor cursors have been sped up, since
both lists can be massive, and waiting 6 frames per line is extremely
slow and boring. This is still slow and boring, but we don't have
proper input repetition yet.
This commit moves everything left out of the previous commit to the
state system. This means a bunch of new functions were added as well,
to avoid the code in each function becoming too huge. A lot of cleanup
was done as well, simplifying logic, merging duplicated code, etc.
This commit does NOT touch "script hooks", script editor logic and
autotiling, as those seem to be their own separate beasts.
Tools were a mess, spread all over the code with hundreds of `else-if`
statements. Instead of magic numbers denoting tools, an enum has been
created, and logic has been extracted into simple switch/cases, shared
logic being deduplicated.
The base of a state system for the editor has been created as well,
laying a good path for further organization improvements. Because of
this, the entire editor no longer gets drawn underneath the menus,
except for a few pieces which I haven't extracted yet. Either way,
this should be good for performance, if that was a concern.
Level text such as room names, text box content, and the contents of
the script editor need to be displayed in the level-specific font, and
tweaked to look right. This involves displaying less lines in the
script editor, making text boxes bigger, displaying some text higher
and some text lower. This is still unfinished, but it's the real start
of a migration to font::print functions!
colourTransform is a struct with only one member, a Uint32. The issue
with `Uint32`s is that it requires a bunch of bit shifting logic to edit
the colors. The issue with bit shifting logic is that people have a
tendency to hardcode the shift amounts instead of using the shift amount
variables of the SDL_PixelFormat, which makes it annoying to change the
color masks of surfaces.
This commit fixes both issues by unhardcoding the bit shift amounts in
DrawPixel and ReadPixel, and by axing the `Uint32`s in favor of using
SDL_Color.
According to the SDL_PixelFormat documentation (
https://wiki.libsdl.org/SDL2/SDL_PixelFormat ), the logic to read and
draw to pixels from colors below 32-bit was just wrong. Specifically,
for 8-bit, there's a color palette used instead of some intrinsic color
information stored in the pixel itself. But we shouldn't need that logic
anyways because we don't use colors below 32-bit. So I axed that too.
If it's at all possible to use `const std::string&` when passing
`std::string`s around, then we use it. This is to limit the amount of
memory usage as a result of the frequent use of `std::string`s, so the
game no longer unnecessarily copies strings when it doesn't need to.
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.
