Okay so I am about done with my map in progress which I will post in a minute after this...I did some major redevelopements which took a long time to do and it sort of upset me to see that I came into a bug.

Well basically you can build a turret (up to 3) to defend your base. I used to have it being player owned turrets, but found that people could just sometimes camp and not send units...and just build up minerals and experience based on their turrets killing. To prevent this...I wanted to switch user control of the turrets...(this was fine and is running smoothly) however, I ran into a problem.

Force 1 (Players 1,2, and 3) all give their turrets to Player 9 while Force 2 (Players 4, 5, and 6) all give their turrets to player 10. I set Player 9 ally force 1 and enemy force 2 while opposite for Player 10. However for some reason their turrets won't attack the opposing forces. This makes me angry b/c I spent over a couple hours changing all player's ownerships and triggers to the specific neutral player [9 or 10].

I don't know what is up and if Player 9 and 10 can't attack...I just wasted 2 hours and am gonna have to go back through again and fix it. If they can attack let me know what I am doing....if there is a problem, and how this can work.

Thanks!

You just wasted 2 hours and are gonna have to go back through again and fix it.

But instead of that, just find/replace Player 9/10 with 2 computer players. Otherwise, plan your map better.

Plan my map better lmao...guy I spent a long ass time planning my map...I didn't think people would sit back and camp to gain their experience///money....so pardon me for improving my own map...

So is giving it to the computers out of the question? If you can't give it to them for some reason, you need to figure out a way to give it to them, possibly using invincibility in some areas.

I missed this in the first part:
Players 9+ can't have triggers, so you'll have to change the ownership to player 1-8. Not a problem if you use computer players, though, and my first method will do that automatically.

I used players 7 & 8 instead...even tho I planned on using them for something else, it isn't a big deal though.

To sum all above posts up:
P9+ are neutral and won't attack. => Use comp players of one of P1-8 if you want them to attack.

Instead of removing control of the turrets for the players you could do a couple of other things:
For example don't give the player xp if he has no units outside his base.
Or give some other kind of reward when he's attacking.
Maybe you are able to detect when the enemy unit's are killed inside an enemy base and don't give xp to the defender then.
Make a system that makes turrets more expensive as you build more (e.g. by indirect build: build depot = create turret, subtract ore)
There are more ways. Just be creative.
