Collision Outline 2D

Link to the Asset Store page

With this asset you can add Outlines to any 2D Colliders in your game. This will either enhance the look of your game or make certain types of Colliders clearer to the player.
The Outlines are generated using the Unity default LineRenderer Component and are therefore easily customizable.
Also the asset comes with a Line Shader and different ways to animate your Outlines.
To make it clear: The asset only works for 2D games with 2D Colliders, as it uses the Collision Shapes of Circle, Box, Polygon, Edge and Capsule Colliders to generate the Outlines!
