For assets in a 2D project to have a physical presence in the Scene and be able to interact with each other, they must have a Collider 2D. A Collider 2D is a component that helps define an asset’s physical shape to determine how it will interact with other Colliders in a Scene. It does this via a built-in physics engine.
In this tutorial, we’ll cover types of Collider 2D’s and how to apply them.
