How do you detect that a camera node in a scene collides with a node in an AR scene?

Chen-Alexander commented 5 years ago

It is best to get the collision event through the callback, because I need to know which two nodes have collided, the specific location of the collision point. PS：By scene.hitTest (Ray), it is not suitable for me, I have tested it.

Thanks!

On every frame, I check with this with the following code:

collisionRay = Ray(camera.worldPosition, camera.forward)
        val result = scene.hitTest(collisionRay)
        if (result != null && result.distance < 0.2f) {
            when (result.node.name) {

You could determine the exact node by setting its name parameter and look for it when collision happens. The exact collision point is out of my scope but I will look for a solution later. I hope this helps
