Levels: Move vs. Warp Object - The-Source-Eternal/Children-of-IO GitHub Wiki
Teaches: game creator code. Specifically: object.move() as opposed to object.warp/object.position
Some platforms in the room can be moved with .warp/.position (no physics), others can only be moved with .move (physics moving, i.e. with collisions etc.). You have to move them to the right spots in the right order in order to create a path for you to cross to the next door.
Are objects that can be .warp-ed colored a different color than other objects?
