Collision Pins are an excitingly easy solution to the complex problem of collision detection in tile based games with tiles of different shapes. In this episode of the Scratch RPG tutorial coding series we look at how this works, how we can store the collision "metadata" in lists, and how to extend out level editor to include the editing of the collison pin meta data itself to speed things up!
