Lets you use a VR world space cursor with World Space Canvases in Unity3D 4.6. Add this to the EventSystem object. Put some box colliders on your buttons in the World Space Canvas. Then, do a trace to see if you're looking at a menu object--if the trace hits one of those buttons, pass it to SetTargetObject. See for a longer e…

Hi Ralph
Thanks for supplying this code.
Can you put the code for your InputManager or a complete demo scene here as well?
Also, what is FlarbCrosshair3D? I am guessing it is a singleton of you custom cursor.

This was the kind of code I was looking for, however I am getting an override error. As LumenDigital stated, could you post a InputManage Demo? It would be very helpful.

grobm, if you take a look at the Base class it is inheriting from then it looks like the method name has changed to public virtual bool IsPointerOverGameObject(int pointerId);
