Its you set everything zero enough to make ai turn into coma state. That AI core part now i working, quite complicated right
The part of problem is, after you make a change you cant simply see the effect first, Building AI core logic, like building rubic cube , its interesting yet also stressfull.Because we even dont know what we change make positive or negative without proper field test which consumed lots of time to be done, just couple of variable. You can count how many variable in AI core logic that needed to be tested.
You also need to have some basic idea, or hypotesis how new AI concept will work. If like solve rubic cube, you must try to predict, if i go left 3 times, righ 2 times, below one time i get zzz on xxx spot. If you start random you get random result. if you luck its work better then before, if not its just do worse.
That the bitter and sweet truth modding AI, that why most modder give up , on AI part because he realized so many times wasted just to make simple proper test for couple variable which they even dont know will its work or not.
