animation clips / refactoring spritesheets

…kinda refactoring the whole spritesheet animation thing already

the first version worked, but having FPS / looping / frame ranges etc directly on the SpriteSheetComponent was gonna get pretty limiting cuz what if I wanted multiple animations for one sprite.

it might sound stupid but for me it’s always worked to get a prototype working, then refactor/reimplement it. thats even what i did for this entire project early on, before it deleoped into a full on engine :D

so now the spritesheet is mostly just the sheet + currently displayed frame, and animation playback is seperate

animation clips

working on proper animation sets + clips.

an animation asset can have one spritesheet and multiple named clips, with each clip containing its own list of frames :D

each frame also has its own duration now instead of the whole animation just sharing one FPS value, so stuff like holding a frame longer or doing irregular timing is possible without

clips can loop independently too

animator component

added a separate SpriteAnimatorComponent which handles the actual playback state:

animation asset
initial clip
autoplay
current clip
current frame inside that clip
elapsed time
playing state

the normal SpriteSheetComponent is way simpler now…
it just says what sheet + frame should currently be rendered
(the animator updates that for it)

animation assets

animation sets are assets now under assets/animations/

they serialize separately and contain the spritesheet setup plus all the clips / frames / durations

they are loaded through the normal asset system and registered in the ResourceManager

scene serialization now keeps the animator config like the selected animation asset, initial clip, and autoplay

editor stuff

the sprite sheet inspector got reworked for the current thing but whole UI stuff isnt finished

once an animator is attached it owns the sheet/frame instead of both systems trying to edit the same thing.

I still need a proper UI for actually making / editing animation assets and clips though. i shall work on this next!!!

(right now the backend is pretty much all ive done but its taken a lil longer than i thought…
who wouldve thought adding cips cleanly would take this whole aah refactor)

scripting

EngineLib updates too

SpriteAnimator in scripts can now do:

Play("walk")
Restart("walk")
Pause()
Resume()
Stop()
IsPlaying()
GetClip()

it is now based on named clips

so i guess not anything flashy to show but… its stuff :)
