Add xrcontroller.js

The 8th Wall sample PlayCanvas projects are populated with an XRController game object. If you are starting with a blank project, download xrcontroller.js from https://www.github.com/8thwall/web/tree/master/gettingstarted/playcanvas/scripts/ and attach to an Entity in your scene.

NOTE: Only for SLAM and/or Image Target projects. xrcontroller.js and facecontroller.js or layerscontroller.js cannot be used simultaneously.

Option	Description
disableWorldTracking	If true, turn off SLAM tracking for efficiency.
shadowmaterial	Material which you want to use as a transparent shadow receiver (e.g. for ground shadows). Typically this material will be used on a "ground" plane entity positioned at (0,0,0)

Add layerscontroller.js

The 8th Wall sample PlayCanvas projects are populated with a FaceController game object. If you are starting with a blank project, download layerscontroller.js from https://www.github.com/8thwall/web/tree/master/gettingstarted/playcanvas/scripts/ and attach to an Entity in your scene.

NOTE: Only for Sky Effects projects. layerscontroller.js and facecontroller.js or xrcontroller.js cannot be used simultaneously.

Add facecontroller.js

The 8th Wall sample PlayCanvas projects are populated with a FaceController game object. If you are starting with a blank project, download facecontroller.js from https://www.github.com/8thwall/web/tree/master/gettingstarted/playcanvas/scripts/ and attach it to an Entity in your scene.
