This was discussed in #706
It also uncovered some off-by-one issues with defining some constants.
A few structs now use rsreset/_RS to define their offset constants, as discussed in #739
The X and Y flip flags can be applied through the stack consisting of:
- Object attributes
- Animation frame attributes
- OAM Data
Each of these negate eachother.
Confused yet? The same stack is traversed to obtain the final tile ID,
with an added layer on top for the base GFX offset and the offset for
the dynamically loaded GFX requested by the object!
wBattleAnimDelay is populated with the values passed to `anim_wait`.
These are used where the head or the feet of the player/enemy have to be
moved in an animation, and shouldn't overlap. These aren't actual GFX
and should be loaded with the proper commands, and they're always loaded
at the end of the VRAM area.
Furthermore, I've defined BATTLEANIM_BASE_TILE, which is the tile from
which battle animation graphics may start to load. This value was picked
to make sure at least an entire pokemon pic fits in the area before it,
even though it doesn't seem very used...
I have no idea why this was a thing (do people store this repo on FAT32
flash drives or something?), but quite a bit of files had a permission
of 755. This isn't really a problem, but it's inconsistent and weird.
