This is the beginning of a portal test project... Version 0.3 is testing a new improved portal collision technique! - I had this idea to switched from the deep portal costumes to simple portal edge costumes. This is how it works: * If you are not touching a wall - all good, no collision * If you are touching a wall, then: ** If you are not touching a portal, then you collide! ** If you are touching a portal, then: *** If you are touching the edge of a portal, then collide *** otherwise, you are in portal and don't collide. So, three costumes checks is all it takes to know you collide with a wall, and whether a portal has cut a hole in said wall for you to pass through. Of course, then there's all the coding to actually make portals teleport the player / and their clone... but that's another story!
