Canvas & Ray Casting

Canvas and Ray Casting

X-Frame automatically manages ray casting for Canvas elements set to Screen Space Overlay or World Space.

ScreenPointToRay Replacement

If you experience issues with Camera.ScreenPointToRay, use the X-Frame equivalent instead. It accounts for the active downsampling factor:

Ray ray = XFrameManager.instance.ScreenPointToRay(camera, screenPosition);

Runtime-created Canvas Objects

If you create Canvas objects at runtime, call UpdateUICanvases() to integrate them with X-Frame's ray casting system:

XFrameManager.instance.UpdateUICanvases();

See the Scripting Support page for the full API reference, including additional raycast and UI interaction helpers.
