Vive controller pointer to only select floor

Hey guys. I´m pretty new to Unity, though I have taken good steps towards creating an archviz experience with Vive thanks to these forums.

My Question is: I am using the VRTK library with HTC vive. I am also using the green colored straight-line type of controller pointer to move around. When I point to the walls I usually end up with half of my head through the wall and its annoying. Is there a way to avoid this? Ive incremented the collsion boxes` size and it doesnt work. Or maybe a solution is to make it possible for the player to only be able to teleport to where he points on the ground.

Thankyou!

Check out example scene number 33, it may have what you need, it will disable their teleport when they would be in the wall where they teleport. Sorry I can’t help more than that, as I’m really unsure how VRTK is supposed to be even used when you want to do anything but click-and-drag cut and paste mechanics. Everything I try to scriptually do is immediately not working.
