Hello there,
I was wondering if you were able to find a solution? I stumbled on the same problem as you did. I tried many different actions and settings with not resulting in a solution. Looking at you're example:
I made something similiar as you did, the only thing I added that I made more objects. For example I made two Obj_1 and two Obj_2, I made an action; Obj_1 adds Obj_1 as obstacle. Second action: Obj_2 adds Obj_2 as obstacle.
In this example, Obj_1 should be able to move through any Obj_2 but not through Obj_1. And same is vice versa. Obj_2 should be able to move through all Obj_1s but not through Obj_2. I can not seem to get it working properly.
Any new advise?
