Triggers

[apeters2525]

IS there an advanced trigger tut out there? i have found basic ones, but I would like one that explains triggers in more detail.

I need to know how to get an enemy group to attacka  position once my group is in the ttrigger, but wont if another friendly group is in.

My group is reporting to patrol duty and relieiving the previous group. The previous grp starts out in the trigger, so I dont want them to trip it...only my group after a timed count down.

Any thoughts?

EDIT: Disregard this. I made a crucial newbie forum mistake. I have found what i am looking for

Seems like you found what you needed - but - I'll post these two things cause they are handy and yes...very noobish stuff  

Triggering a Trigger:

Trigger 1
On activation : A1 = true

Trigger 2
Condition: A1
On Activation : what you want.

And.....

Get a trigger to activate only by a specific unit:

Select Group (press F2) and drag a line from the trigger to the unit in question.

Tada! come'on! Someone will apreciate it! :-\
