move_wrap(hor, vert, margin);
|hor||Whether to wrap horizontally (true) or not (false).|
|vert||Whether to wrap vertically (true) or not (false).|
|margin||How far outside the room, in pixels, the object must be to initiate wrapping.|
This function will automatically "wrap" an instance that has
left the room on either the horizontal or vertical (or both) axis.
You can specify a margin outside the edges of the room for this to
occur, and when the instance has travelled outside of that margin
GameMaker: Studio will automatically wrap it back into the
room at the other side. Note that the instance must have a speed
for wrapping to work, because the direction of wrapping is based on
the direction of the motion.
move_wrap(true, false, sprite_width);
This will make the instance wrap horizontally but not vertically, when it is over its own sprite width outside of the room.
