Yeah, getting different values for all the NPCs is what I need, but I don't understand the method you told me to try, as I tried applying this but the result didn't go as you said. (well, I think I'm missing something because to be fair I'm not English native)
If you need a serie of different values ( all the values different I mean ) you could just use a counter, increment it and give the counter value to the current target. When the counter reaches the max actionchance ( 160 ) then set it again to 140. Same for countcapchance, just set a second counter for that.
Can you make an example MFA of what you mean? I'm reworking the NPC engine and so far the count function is the only thing left that I need, sorry, I'm not really experienced in making AIs, I'll check how it works in depth. Thanks if you read this.
