I am working on a guns script and currently attempting to make it when the bullet has reached a certain distance away from its spawn point it looses a set amount of damage here Is the whole Bullet part of the script thanks for your help :D 

local function CreateBullet(mouseLookVector)
	local NewBullet = Bullet:Clone()
	local ShootAnim = myHuman:LoadAnimation(AnimationFolder:WaitForChild("Shoot"))
	NewBullet.CFrame = BulletPoint.CFrame
	
	local direction
	
	local OriginalDamage = GunInfo.Damage
	
	NewBullet.Configs.Damage.Value = GunInfo.Damage
	NewBullet.Configs.Headshot.Value = GunInfo.Headshot
	NewBullet.Configs.HeadshotMultiplier.Value = GunInfo.HeadshotMultiplier
	NewBullet.Configs.BulletDamageFallOff.Value = GunInfo.DamageFallOff
	NewBullet.Configs.BulletDamageFallOffDistance.Value = GunInfo.DamageFallOffDistance
	NewBullet.BulletVelocity.Velocity = direction * GunInfo.BulletSpeed
	NewBullet.Parent = workspace["Bullets and Casings"]
	ShootAnim:Play()
	BulletPoint:WaitForChild("Shoot"):Play()
	wait(GunInfo.FallOffTime)
	if NewBullet then
		if NewBullet:FindFirstChild("BulletVelocity") then
			NewBullet.BulletVelocity:Destroy()
		end
	end
	if NewBullet then
		NewBullet.Velocity = mouseLookVector * GunInfo.BulletSpeed
		
		local lastPos = BulletPoint.Position
		while wait(0.001) do
			
			print((NewBullet.Position - lastPos).Magnitude)
		
			
			if NewBullet.Position >= GunInfo.DamageFallOffDistance then
				GunInfo.Damage = GunInfo.DamageFallOff
				
				wait(0.6)
				
				GunInfo.Damage = OriginalDamage
					
			end
		end
		
	end
end
