make 2 object not collide?
i have 2 objects with colliders. One is a player and one is a rigidbody. i want them to collide with everything(floor, walls, clones of self, etc.) except each other. How do i do that?
The easiest way is with the Collision layers matrix
http://docs.unity3d.com/Documentation/Components/LayerBasedCollision.html
create a layer for each object (select the object, choose "add layer")
the first 8 (layer 0-7) are reserved (built-in layers..) use any of the user layers (8 up)
select the object again, after creating a new layer, to make sure it is set to that layer
then uncheck the layers from their intersection in the matrix

This probably only works for 3D bodies. I'm trying this with 2D colliders and it's not working.
I got it to work for 2D. I used DryTear's solution, except Unity also has it for Physics2D. So I ended up putting Physics2D.IgnoreLayerCollision(8, 9, true); in the Start() method of a script. Now the layers don't collide.
Try looking up for Physics.Ignore
