Title: 2 mesh colliders not colliding
Post by: p0wn on February 08, 2013, 09:14:23 pm

I'm new to both Unity and 2d Toolkit.

That said I've set up 2 sprites on top of each other with polygon mesh colliders with a z scale of 10. One's rotation and position is locked, the other is only rotationally z-locked. Here's a screen capture of the setup http://cl.ly/image/1l1n2V0x0A2j

Any reason why when I click play the one on top just falls through the other one?

Yes, Unity doesn't allow 2 polygon colliders to collide, unless at least one of them is convex. Thankfully, in your example, those shapes are convex. All you need to do is tick "Convex" in the sprite collection editor, and you're good to go.

You may want to update http://www.unikronsoftware.com/2dtoolkit/doc/tutorial/creating_polygon_colliders.html and make it so in the tutorial you check the convex  button. Very confusing to the n00b otherwise.
