Following on from defining our Collision Pins in episode 7, we now finally add the player collision code to make it real! These collision pins support both hairline edge collision boundaries, and half tile collisions!
We do some clever tricks to invert the hitboxes, support overlapping collision pin regions, and span tile layers! This is one crazy awesome episode, and I just know you are going to love it! Our Scratch RPG game is really shaping up!
