2D Colliders Expanded

A Unity2D Collision Improvement Project

Created by Timothy Kebr, October 2015


Right now, the project adds the following new colliders to Unity’s 2D Collision system:

  • Curved Edge Collider 2D
  • Semi-Circle Collider 2D
  • Capsule Collider 2D


Unity’s default 2D colliders are lacking. Is the shape you want too complicated to create with just the default colliders? Need some curves? 2D Colliders Expanded seeks to fill some of those gaps in a native-feeling way.


  • Attach the script to a GameObject
  • The collider will be created as you change the editor values
