Hi, I am currently experimenting with the free version of A* to try to build my AI solution. I would like each AI unit to maintain a list of objects that it sees as obstacles (i.e. enemies) without the object becoming an obstacle for every other AI unit so I wouldn't want to use tags or layers. A scenario would be an AI unit walking around investigating another AI unit and making a determination of it being friend or foe. Is that possible, do I need the pro version? I have scripts that would make the determination I just want to know if I can have a single AI unit avoid another AI unit dynamically.
