creep triggering

creep triggering

i want to know waht would be the best way to go about this.

i want a system to make wandering creeps that will respawn short after, and i want far wandering, not like the ability that moves really slow.

if u have anything, pm me, cause im not on my comp and its hard to find my forums

o and also, i still need a good terrainer, and again, pm me
