You can use -1 or 0 for the maxdist being a default 1000px, ie: GameMaker: Studio will move the instance continually up 1000 pixels until it is out of collision.


if !place_meeting(x, y + 1, all)
   move_contact_all(270, -1);

The above code will check beneath the instance for a collision, and if there is none, then it will move it down until there is or until 1000pixels have been covered.
