Hostile Creeps Revive System

[MetalZoa]

Hello friends, i came to ask for urgent help... i created a system to revive Hostile Creeps but I would do it like DotA or something. I need that when i build a Town Hall near the area, they can not revive temporarily or while viewing a player in that area. What could be added to achieve that? I would greatly appreciate your help. Greetings.

Make a range check. If a Town Hall is with X range of the spawning point, don't spawn the creeps.
