I have tile based map, where agent needs to go from one tile to another, Some tiles have (occupied pos-X-Y) meaning that agent cant step on these tiles named pos-X-Y. This part works, but I need to make these tiles occupied only in certain turns. I tried to use action-cost and add a number to each (occupied pos-X-Y) like this: (occupied pos-X-Y Z) planning to compare the Z number with the current action-cost. But I couldnt even assign the number to the occupied tile.
How do I assign a number to these occupied tiles and how do I compare it with the action-cost?
I figured it out (with help). Instead of using numbers I created many objects, I will call them turns, then I set that, turn 2 is always after turn 1, turn 3 is always after turn 2 etc. and I added these turns as the letter z in "(occupied pos-X-Y Z)". And when actor moved I just changed his turn to the next number based on the rule I created earlier.
