i wnat an ultralisk every 2 seconds to attack a certain place but sort of randomly do it, like MT impossible in BW

You need to be a little more specific. Not everyone knows MT impossible. Also:

• Why don't you just do it? What is the problem?
  
• What did you try already?
  
• Do you prefer a trigger or a data solution?
  
• How specifically should this attack work? Attack random targets in an area? Deal AoE damage?
  
• How should your randomization work? Random points in a specific area? One random point out of a list of specific points? Randomly run across the map?
  
• Should an attack be ordered every 2 seconds, or should an attack happen every 2 seconds?

Well, i am not really sure to most of those questions, but what i have done so far is this :

• Periodic event every 2 seconds

(before i did this ultralisk is added to unit group)

• Order unit group ultralisk to attack move region start

nothing happens.

crazy

PS. Sorry I cant really describe this that well, but anyone who has played Mt impossible in sc1 knows what i mean of how the ultralisk changed its attack every so many seconds, At the bottom of that map it had a turret which kept getting blown up. you can see youtube videos about it.
