got teach trigger or not?

i wan to learn how to set the trigger like the monster would spaw automatic and will go atk ppl...

I personally think you should look at the Trigger editor alittle before asking questions but I still will answer it:

Action-Create unit facing angle
or
Action-Create unit facing point

and
Action-Unit issue order....(there are abunch and the one you want depends on the order you wish to issue)
