Any way to read editor's Physic2D "Layer Collision Matrix" in script?
Hi,
I basically want to read this:
in script.
Thanks
Well, just use Physics.GetIgnoreLayerCollision to check the values set in the matrix and use Physics.IgnoreLayerCollision to set a value for two geven layers.
I'm not sure in which Unity version those two methods got added, but in the past it wasn't possible at all to access or change that information.
VERY IMPORTANT! There are 2 collision matrices, one for Physics, and one for Physics2D. To read Physics2D's collision matrix, use Physics2D.GetIgnoreLayerCollision, not Physics.GetIgnoreLayerCollision.
As far as i remember in the past there was only one but they splitted it up since they are essentially complete seperate systems. Though it's unlikely that you actually will need 2d and 3d physics at the same time.
Anyways of course you're right.
