Ok, i'ts been a long time sience i used the editor so some of the trigger examples may be off.
Events - Game Time Elapsed is 5 Seconds (for some reason you can't make it as "Map Initsilization" , it just dosent work =/)
Conditions - None
Actions - Create Dialog named Dial0g1
Set Variable (Dialog) = Dial0g1
Create Dialog Button For Dial0g1 labeled "I'm a gay anal noob"
Set Variable (Dialog Button) = "I'm a gay anal noob"
Create Dialog Button For Dial0g1 labeled "He's a gay anal n00b"
Set Variable (Dialog Button) = "He's a gay anal n00b"
Display dialog for (All Players)
Then to make the buttons do thing you would do something like this.
Events - A Dialog Button is Clicked (or something like that)
Conditions - Button Clicked Equal to "i'm a gay anal noob"
Actions - Create 6 "Sexy Man-sluts" at "MAn Whore field" (region)
Hope that helps, If not, Someone with more expirence can make it a bit clearer.
