unit groups

yep its me again your friendly neigborhood noob, for the map im making i need to put units in a group, i did this by adding 7 units to a unit group variable called u1 (not an array) then i make a trigger to make emey units attack a random unit in that group, problem is they dont... plz help

I think I have the solution to your problem. Be sure that you have some way of calling your attacking unit. For example, I would store the attacking unit as a variable. I'll call it EnemyUnit for now. Only one trigger will be necessary to accomplish this:

Trigger 1: Attack Random Unit
Events:
&nbsp&nbsp&nbsp<Your events here>
Conditions:
&nbsp&nbsp&nbsp<Your conditions here>
Actions:
&nbsp&nbsp&nbspUnit - Order EnemyUnit to Attack (Random unit from u1)

And that should be it. It's pretty easy. Do you need a tangible map so you can see the actual triggers work? Let me know, and I'll make one as soon as I can!

i need about 30 units attacking not just 1

How about Pick all units in YourRegionOrUnitGroupVariableHere and do the same thing as he said?
