GetCreeperInArea(<-area <-ac <-withdamage)
Adds up the creeper, or AC, in the specified area. The area is a V4 that specifies the world position. It specifies the lower left and top right corners of a rectangular area. If “AC” is true, then AC is summed. If “withDamage” is true then any pending damages is subtracted from the calculated creeper total.
