Levels:

• ignore comments in lvl files

• Grid Observer: https://github.com/mlange-42/arche/issues/374

• Add shaders for animation (player destruction etc)

• Start New game starts with last played level, better add a Resume Game menu item for this and use Start New always for level 1.

• for finding caller: pc := make([]uintptr, 10) n := runtime.Callers(0, pc) pc = pc[:n] fs := runtime.CallersFrames(pc) source, _ := fs.Next() source, _ = fs.Next() source, _ = fs.Next()

  slog.Debug("get observer", "minmoves", observer.LevelScore, "file", source.File, "line", source.Line)

• Turn menu button in hud_system (events in level_scene!) into ebitenui button

• Obstacle don't stop at collectibles

• 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.

Collider Rework [abandoned: see branch collider-system, fails]

• do not use the map anymore for collision detection
• central collision_system
• add Collider component with callback funcs to call on certain events
• callback types:
  • rect intersect (== future collision)
  • collision resolve (set new position)
  • pass over foreign rect (to e.g. change sprite while flying over sprite)
  • pass over done (switch sprite)
• check for all moving objects against non-moving ones like moving obstacle, player, bullet, laser
• check if executing callbacks within query loop is allowed
• callback function needs to be able to modify other components, so possibly use observers for them, e.g.: Collider.IntersectResolve => func(newpos) {player.pos = newpos; player.vel = stop}
• in the end it must be possible to add new entities without the need to write a collision check for them, but have collision detection anyway!
