Still having trouble dealing with multiple instances of one object

[Outcast]

I feel like I have progressed very much in my knowledge on mmf and how to do things over the years. There is however one part I still always have problem with, and that is handling multiple instances of one object, interacting with other objects.

For example, say I have a game where you have a warcraft style game where you have workers going around cutting down wood for you. As long as you have one worker everything is fine. Just pick a tree at random, have the worker go there and cut it down, go to next and so on. But I always get problems when I am dealing with multiple ones. So now I have 2 or 3 workers that when idle should go to a free tree (not one already targeted by another worker) and start cutting on it. Instantly I get in all sorts of problems where workers "cluster up" on the same spot, goes to the same place, stops altogether, and all sorts of "bugs" i can't solve.. :/

What is the easiest way to deal with something like this? Should I use ForEach loops (the ones inbuilt in the new 2,5?) Or is that not necessary? I have done this kind of thing before and eventually got it to work, but it seems I never feel I get a clean way to do it that feels intuitive and straightforward :/

It sounds like you need a fastloop.

If you were able to manage to do things without fastloops, I'd imagine it would involve use of automatic pairing. I found this tutorial very informative.
