number of pixels in the specified direction until it meets
any other instance with a valid mask. 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.
