WebInputEventManager

class WebInputEventManager(canvas: HTMLCanvasElement, eventQueue: ZEventQueue?)(source)

Manages the capture and conversion of DOM input events (mouse and keyboard) for a canvas element, converting them to Zernikalos events and enqueuing them in an event queue for synchronous processing during the game loop.

This class handles:

Registering event listeners on the canvas
Converting DOM events to Zernikalos events using adapters
Enqueuing events in the event queue instead of processing them immediately
Cleaning up event listeners on disposal
