That's because Step Event defined for the object is executed for all existing instances til that moment. That means, you are performing n collision checkings per instance, for a total of n 2 total operations.

Gamemaker studio 2 collision code#

Your current code will make every instance of obj_Cell to execute a snippet for any current instance of obj_Cell, to check for collisions. Let's say, there are n instances of obj_Cell. Putting a with statement in the Step Event of an object whose object_index is the same as the statement's will slow down your game very, very much. The only thing you need to do is removing the with statement. My question is, is there a way of doing the same but faster? As it is, the number of times these scripts need to be run is the square value of total number of cells in the room, I intend to have hundreds of cells simultaneously.

do the thing that should be done when two foreign cells touch If other.ID_M圜ore!=ID_M圜ore //.and your core is not the other cell's core If place_meeting(x,y,other)=true //if you are touching the cell that is runing the script. The annotated version of the above: with(obj_Cell) //get every cell in the room to do the following: The following code is used, it is run in the step event of every Cell with(obj_Cell) The purpose of this is to know which Cells are overlapping with a 'foreign' Cell.

Each Cell record its corresponding Core with the variable ID_M圜ore, which is the id of its Core.Ĭollisions/overlapping between Cells belonging to different Cores are to be detected. There are many objects named obj_Cell and obj_Core in the room, each Core has a number (0 to 10) of Cells that belong to it.
