Still not convinced by a c_move (movement) approach but otherwise, very cool! I'd be interested in a video of a group of units moving through the gate (and accessing the 2nd floor would be cool, too, if you manage to fix it)!
thanks okay I'll make a short video maybe next week. the floor bug is just fixed a few minutes ago, beside some other wrong helper functions...
I decided beside c_move after checked again some Total War games, where there is apparently no exact unit pathfinding, only a group level potential field, and a formation keeping potential field for units, so units simply push away other units when groups are going through each other. this is why you can see many pathfinding problems, which is lowered at gates and towers/walls, where they use probably a different, maybe a hardcoded movement. I can use this approach until I find it effective (very short collisions).
