Weapon Realism Mod Help
 

i am making a weapon realism mod and i need some help from the experts here! for the shotgun, how do i make each pellet that inficts 15 damage lose 25% of its power for every 10 yards it travels for the gun?

example: inflicts 15 damage at 10 yards, inflicts 11.25 damage at 20 yards, inflicts 7.5 damage at 30 yards and so on!

keep in mind that the pellet spread has nothing to do with the damage factor of each pellet!

i guess it's impossible to do without editing the game code! :P
