This script has features:

1. Create a LineRenderer: developer can see a ray being shown on screen.

How to use

In editor mode, developer can play scene to see the effect.

Use “right alt” and mouse to controll the rotation.

Script

Developer can see four public variables:

1. Device Index: index of connected device. It is for use with next variable - Listen To Device.
2. Listen To Device: if checked, the LineRenderer is only generated when controller with specified Device Index is connected. Otherwise the LineRenderer is always created.
3. Add LineRenderer: if unchecked, the LineRender will never be created. This can be unchecked if developer does NOT wanna use LineRenderer. (eq. use Mesh)

When device is connected or disconnected, OnDeviceConnected will enable / disable the LineRenderer.

private void OnDeviceConnected(params object[] args)
{
    var device = (WVR_DeviceType)args[0];
    var connected = (bool)args[1];

    if (index != device)    // check if the role of connected device is equivalent to developer specified index.
        return;
    if (lr != null)
    {
        lr.enabled = connected;
    }
}
