I have a 2D level that I have built in my map editor, and I was wondering the best way to create a collision map for it.

I have a collision map layer in my map editor, which saves each node (for example, a rectangle would be just 0,0 0,50 50,60 0,60)

I was just wondering how I could take my node locations and convert it to a collision map for Unity.

Thanks! I feel this has to be able to be done, I can think of how I would do it in flash... but I am not sure how to manipulate it in Unity.

EDIT PICTURE: So I have a node at each one of these red dots (surrounding my terrain lets say) I want to build a collider from those nodes
