/**
 * Animator plays and manages state-machine based animations on a GameObject.
 * Uses an {@link AnimatorController} for state transitions, blending, and parameters.
 *
 * **State machine animations:**
 * Define animation states and transitions in Unity's Animator window or in [Blender's Animator Controller editor](https://engine.needle.tools/docs/blender/animation.html)
 * Control transitions via parameters (bool, int, float, trigger).
 *
 * ![](https://cloud.needle.tools/-/media/zXQhLgtxr5ZaxLDTDb3MXA.gif)
 *
 * **Creating at runtime:**
 * Use `AnimatorController.createFromClips()` to create controllers from code.
 *
 * **Parameters:**
 * - `setTrigger(name)` - Trigger a one-shot transition
 * - `setBool(name, value)` - Set boolean parameter
 * - `setFloat(name, value)` - Set float parameter
 * - `setInteger(name, value)` - Set integer parameter
 *
 * @example Trigger animation state
 * ```ts
 * const animator = myCharacter.getComponent(Animator);
 * animator.setTrigger("Jump");
 * animator.setFloat("Speed", 5);
 * animator.setBool("IsRunning", true);
 * ```
 *
 * @example Listen to animation events
 * ```ts
 * animator.onLoop(evt => console.log("Animation looped"));
 * animator.onFinished(evt => console.log("Animation finished"));
 * ```
