    Interface OnAction

    ActionManager - Centralized event listener management utility.

    Prevents memory leaks by tracking all registered event listeners and providing batch cleanup functionality. Particularly useful for Logic components that need to register multiple window/document listeners and clean them up on destroy.

    When adding event listeners in game logic, forgetting to remove them causes memory leaks. ActionManager tracks all listeners and provides a single removeAll() call for cleanup.

    • window - Global events like resize, blur, focus
    • document - Keyboard events, pointer events that shouldn't be canvas-bound
    • renderer.canvas - Canvas-specific events
    • Any DOM element
    • Pointer: 'pointerdown', 'pointermove', 'pointerup', 'pointercancel'
    • Mouse: 'mousedown', 'mousemove', 'mouseup', 'wheel', 'contextmenu'
    • Keyboard: 'keydown', 'keyup'
    • Window: 'resize', 'blur', 'focus', 'visibilitychange'
    // In a Logic component - drag handling with cleanup
    class DragLogic extends Logic<Container> {
      private actions = new ActionManager();

      init(entity: Container) {
        // Add listeners - they're tracked automatically
        this.actions.add(window, 'pointermove', this.onMove.bind(this));
        this.actions.add(window, 'pointerup', this.onUp.bind(this));
        this.actions.add(window, 'blur', this.onBlur.bind(this));
      }

      destroy() {
        // Clean up all listeners at once - no memory leaks!
        this.actions.removeAll();
      }
    }

    // Removing individual actions
    const wheelAction = actions.add(window, 'wheel', onWheel);
    // ... later ...
    actions.remove(wheelAction); // Remove just this one
    interface OnAction {
        handler: EventListener;
        options?: AddEventListenerOptions;
        target: EventTarget;
