Module sprite_anim 

Sprite Animation System — frame-by-frame ASCII art animation.

Provides a SpriteAnimator that drives frame-based animations for entities in the Chaos RPG. Each animation is a sequence of SpriteFrames, where each frame is a collection of positioned, colored glyphs forming the ASCII art.

Architecture

SpriteAnimator
  ├─ animations: HashMap<String, SpriteAnimation>
  ├─ current: String (active animation name)
  ├─ frame_index: usize
  ├─ frame_timer: f32
  └─ state_machine: AnimationStateMachine
        ├─ states: HashMap<String, AnimState>
        ├─ transitions: Vec<AnimTransition>
        └─ params: HashMap<String, f32>

Pre-built Animations

The module includes ready-to-use animations for:

• Enemy: idle, attack, death
• Bosses: unique idle and attack per boss type
