New ideas for proximity

I see a lot of potential in proximity- they are SUPER helpful in my games, but kinda is too limited for certain things.

The moving health bar is really helpful in my games, but the bad thing is since enemies will only spawn through emitter, I need the proximity to work on that. And just to make sure so the bar doesn’t gets swapped with a nearby enemy, I want there to be a “lock on” command, which once it goes after that one, it only looks for the same one each update, but the extracter doesn’t work with that since it’s too specific and doesn’t list emitted OBJ
