Loop it from start : (What you need & example)
trigger_start
trigger_delay
trigger_delay
trigger_delay
env_hurt
env_hurt
env_hurt
Trigger_start - (Triggers : A)
trigger_delay - (Named : A - Triggers : B) 3 Seconds Delay
env_hurt - (Named : B)
trigger_delay - (Named : B - Triggers : C & B) 6 Seconds Delay
env_hurt - (Named : C)
trigger_delay - (Named : C - Triggers : D & C & A) 9 Seconds Delay
env_hurt (Named : D)
So there you go! A loop is made from the start of the round in the map... it will trigger the env_hurt in the places you want the env_hurt to be...
You can also do it with other triggers like : Trigger_Hit/Move/Use
I hope this helps you with the looping problems...
