Fastcast Redux Pierce Function Issues

Help and Feedback Scripting Support

  1. Howdy i’m trying to get the pierce function to work after the “defeated armor” variable is true, it is for sure becoming true but the pierce function isn’t doing it’s job, also i’m having another issue where the pierce function doesn’t work the first shot but works the second

  3. I have looked for solutions and have found no applicable advice, i have also tried to fix it for about 2 hours and have failed

I am quite new to coding and any advice would be appreciated.

damage function checks armors blunt and sharp protection and then subtracts it agianst the bullets blunt and sharp damage and if the bullets damage values are higher it will penetrate issue being this is not happening
