so im making a map where the player needs to use the 'a' or 'attack' button to attack and this can be done using alliances (set to ally).
one thing i dont get is sometimes the unit will not attack, and this is from the time after you click 'a' on a unit you want to attack, but then your unit will begin to move over to attack, but stops mid-way. that is because the trigger is either preserved to set to ally, or just waiting milliseconds to ally, and it ends up allying half way through the attack. i want to know how to make it ally each time after you attack and kill the unit, should i use kills?

You can detect when their kill score goes up and reset the ally, that, or you can only set them to ally when they have an enemy.

wouldnt detecting the kill score only detect when a kill is made causing that to be the only time they r allied? what if they click un ally each time before a kill?

I'm pretty sure you're looking for a way to prevent people from ever unallying right?

Well if you constantly chance any alliance status, any force attack will be canceled during the trigger run. Using hyper triggers, this prevents most units from ever attacking. The easiest way around this is to detect when a player unallies another player. To do this, you use the "foes" player group. Somehow you need to differentiate the players. If you have unique units somewhere on the map, you can use those (ie foes commands at least 1 "unique unit" then set player X to ally). If not, you can set unique deaths for each player (player 1 has 1 death of cantina, player 2 has 2 deaths of cantina etc...). Then detect when foes have exactly 1,2,3 etc... deaths of cantina and set alliance accordingly.

Finally, if you have NO enemies, you can always just detect when foes have at least 1 any unit, then ally everyone.

Make the condition: if foes command atleast 1 any unit
Make the action: set player(x) to allie
Make the action: Display text: Don't try to unally.
Preserve Trigger

thanks guys
