- Player can collect collectible hidden under obstacle (should be
fixed when above is fixed)
- Get rid of particle system, rather add an animation component, which
determines if an animation must be played according to LDTK entity
settings. Say, something like a boolean value "DetonateAfterHit", if
true, we load the sprites specified in the string value
"AnimationSpritesPattern", where we could have something like
"collectible-detonating*.png" or we could use an animation map and
specify a list of coordinates, etcpp.
- Part I of the above: DONE.
- Part II:
- grid/grid.go:
- add Animation component to mappers
- check if the tile has tile.AnimateOnDestruct (or any other
triggers) set and configure animation compontent accordingly
- check if the tile has tile.AnimationSpriteSheet, assign to Animation.Tiles[]
- do it for any entity not just collectible so that any entity can have an animation
- rename Animation.Tiles to Sprites
- change animation_system to use this stuff instead of any hardcoded values.
