Method onCollisionStart

packages/melonjs/src/renderable/trigger.js:240–244

* Fire the trigger when an entity first enters the trigger zone. * Using `onCollisionStart` rather than `onCollision` so the event * runs exactly once per entry — under the legacy alias this would * fire every frame the entity was inside the trigger.

	 * fire every frame the entity was inside the trigger.
