Change variable for all instances one at a time using proximity

[Brackleforth]

Hello,

I'm trying to change a variable from false to true for all instances of an object.

However, I need the values to change one at a time according to which is the closest to the player object. So, the nearest object changes, then the second-nearest, then the third-nearest, etc, all in one process. Is there a way to select objects, in a for loop using instance_nearest maybe, and adjust their variables one at a time like that? I feel like this should be possible, but I can't visualize what to do.

Thanks!

Yeah.. I'm doing the same in my game.
1. Get a list of objects that are in range (circle) from a object (check getInstancesInRange in gmlscripts)
2. Create a priority list, then:

• Iterate the previous list of instances with a for loop
• Get the distance between origin and the iterated instance (distance_to_object)
• Add to the list a relationship of IDs and distance between instances and origin

  ds_priority_add(dsListId, objId, distanceFromOrigin)

3. When you use ds_priority_delete_min you will get the nearest instance ID of the previous list

Probably it is not the best method but this works fine and fits my needs
