Windows distance_to_object in the left or right side of the player

[Rafael Augusto]

I need a get right or left side of distance_to_object(Pak). For example if distance_to_object(Pak) < 80 only in the left side of the player.


(distance_to_object(Pak) < x - 80) // ?????

Don't use distance_to_object() for this type of thing, you should write your own distance checking function when you require more granular control like this:

var _instances_to_the_left = [];
with (Pak) {
   if (x >= other.x-80 && x < other.x) {
      array_push(_instances_to_the_left,id);
   }
}
// The local variable _instances_to_the_left now holds an array with all the instances of Pak that are within 80 pixels to the left of the instance running this code

That will be 80 pixels rectangular distance. If you're looking for circular distance, keep your code structure the way it is (though note that this only works for one instance of the object being checked, not multiple - that would require an iterative list-based approach like in the post above), but filter out anything with an x coordinate greater than the calling instance's x coordinate.

Familiarize yourself with the coordinate system, e.g. that negative x is left, positive x is right, negative y is up and positive y is down. By combining this logic with simple comparison operators, you can easily check against the basic cardinal directions.
