Class: XRSessionSystem

Defined in: systems/XRSessionSystem.ts:27

Owns the immersive-session lifecycle and fans XR events out to Behaviours.

Detects session start/end by polling renderer.xr.isPresenting rather than binding to sessionstart/sessionend: the session may already be running before this system is registered (the consumer owns the entry button), and polling a boolean makes the system correct regardless of construction order.

Hook dispatch mirrors ImageTargetAnchorSystem's AR precedent — walk live ScriptComponent.scriptInstances and call the public no-op hook — so XR and AR extend Behaviour the same way.
