solved !Help !Help !Help ...Unable to click on 3d buttons in 3D panels.

[oschakravarthi]

Hi,

A strange problem,

I have a SpherePanel with some buttons. I am using Oculus Go. The white color line coming from the controller is not reaching upto the panel even though the panel is very close. (May be it is thinking that there is no clickable stuff ahead).

            var button = new BABYLON.GUI.HolographicButton(Id);
            this._guiPanel.addControl(button);

            var evt = new BABYLON.ExecuteCodeAction(
                {
                    trigger: BABYLON.ActionManager.OnPickDownTrigger,
                    parameter: 'r'
                },
                someCallback);
            button.isPickable = true;
            button.actionManager = new BABYLON.ActionManager(_this._scene);
            button.actionManager.registerAction(evt);
            button.onPointerDownObservable.add(someCallback); 

 

I am setting both BABYLON.ActionManager.OnPickDownTrigger and onPointerDownObservable (I really don't know whether I should subscribe to both the events are which one) but it is not reaching upto the buttons. 

 

Please help me.

The problem is coming only in VR mode. Any clue?

If you create a playground with just the buttons and don't load anything else does the ray work as expected? My guess is that something else you are loading into the scene is blocking the ray,

Hi,  it was due my wrong implementation due to my poor understanding of ray and mesh selection predicates. Looked into Babylon na code and understood the concepts clearly. Now everything is working fine. Thank you @trevordev
