Setting a CullingMask in code

Unity Engine
1

Being a relative beginner to programming, I’m having trouble using bitshifting to make the right CullingMask for my camera in code (C#). Here’s what I’ve got:

  • Layer 8
  • Layer 30
  • Layer 31
  • A camera that I want to see only these layers.

I know how to set only one layer as the CullingMask, but I can’t figure out how to set it to all three of these. Can anyone help me out?

Thanks!

public LayerMask myLayers;

Then set them in the inspector; no need for bitshifting.

Eric,

Thanks for the help, but unfortunately I can’t take that approach in this case. I’m creating the camera through code, and the CullingMask could be different every time (based on what’s currently in the scene), so I can’t set them in the inspector. How would I create the example from the first post with bitshifting?

Thanks again-
