Currently, move_bounce_all and move_bounce_solid are bugged, so I can't test with them. These functions have traditionally worked with bouncing on objects. Now that we have tile based collision systems, I'm wondering what will become of functions like move_bounce? Will we need to use hidden instances for collisions after all if we want to use these functions? Will these functions work with tiles as well as objects? Will there be a move_bounce_tile function to work with tile-based systems? What other GML functions are also affected by this type of concern re: tiles? Move_contact, move_outside? What about the motion planning functions (mp_*)?
