position_change(x, y, obj, perf);
|x||The x coordinate of where to change colliding instances.|
|y||The y coordinate of where to change colliding instances.|
|obj||The new object the calling object will change into.|
|perf||Whether to perform that new object's Create event (true) or not (false).|
This function will check a position for a collision with any
instances at the given point, and if there is one, it will
change all instances in collision to be instances of the
chosen object. You can set the "perf" argument to true
which will force GameMaker: Studio to perform the destroy
event of the found instance and the create event of the new
instance, or false to not perform either of these events.
Please note, that if you choose not to perform the destroy and
create events, any instance created that uses a variable normally
defined in the create event will crash the game as that variable
will no longer exist.
position_change(200, 200, obj_Bird, true);
This will change all instances colliding at point (200,200) into an instance of "obj_Bird", performing "obj_Bird"s Create event for each of them in the process.
