Help with scale damage.

[Crudcakes]

I have a problem with a particular piece of code which until a few weeks ago has been working fine.

local function ReduceDamage(ent, dmginfo)
			local infl =dmginfo:GetInflictor()
			local att =dmginfo:GetAttacker()
			local amount =dmginfo:GetDamage()
			if activator:IsPlayer() and ent.ShouldReduceDamage and dmginfo:GetDamage() then
				dmginfo:ScaleDamage(.1)
			end
		end
						 
		hook.Add("EntityTakeDamage", "ReduceDamage", ReduceDamage)
	
		end

It was working fine so i don't know if an update broke it or not.

Any help is appreciated.

The whole file is here.

Move the hook outside of any of other functions.

Are you talking about moving the whole scale damage piece outside of the Ent:touch function then i cant.

I am sure i have done something wrong. I only know some gmod lua basics.
