问题
In this example:
https://glitch.com/~query-aframe-cameras
I have registered a component which launches a projectile in the direction the user is looking (with a little boost for elevation)
Spacebar
or Screen Tap
to launch - be sure to be looking above the horizon!
It fails in mobile vr (stereo camera) mode:
Projectiles continue to fire, but from the default orientation of the mono, not the stereo camera
I'm using:var cam = document.querySelector('a-scene').camera.el.object3D;
var camVec = new THREE.Vector3();
var camDir = cam.getWorldDirection(camVec);
to get the camera information and spit the projectiles back
