DarkRP addMoney is a nil value

[Bear1ySane]

I made this string of code and added it into the darkrp modules:

function GM:OnNPCKilled(victim, killer, weapon)
        if victim:GetClass() == "npc_zombie" then
            killer:AddMoney(10)
        end
        if victim:GetClass() == "npc_fastzombie" then
            killer:AddMoney(20)
        end
        if victim:GetClass() == "npc_poisonzombie" then
            killer:AddMoney(100)
        end
    end
end

But everytime i kill any of those npcs it will add the cash and give me this error in console:

[ERROR] gamemodes/darkrp/gamemode/modules/zombie cash/sv_zombiecash.lua:3: attempt to call method 'addMoney' (a nil value)
  1. unknown - gamemodes/darkrp/gamemode/modules/zombie cash/sv_zombiecash.lua:3

How can I fix this?

------------------------------------------------------------------------ THIS IS MY CODE NOW v

function GM:OnNPCKilled(victim, killer, weapon)
    if victim:GetClass() == "npc_headcrab" and killer():IsPlayer() and IsValid(killer) then
        killer:addMoney(5)
    end
	if victim:GetClass() == "npc_zombie" and killer():IsPlayer() and IsValid(killer) then
        killer:addMoney(15)
    end
    if victim:GetClass() == "npc_fastzombie" and killer():IsPlayer() and IsValid(killer) then
        killer:addMoney(75)
    end
    if victim:GetClass() == "npc_headcrabzombie" and killer():IsPlayer() and IsValid(killer) then
        killer:addMoney(200)
    end
	if victim:GetClass() == "npc_poisonheadcrabzombie_elite" and killer():IsPlayer() and IsValid(killer) then
        killer:addMoney(1000)
    end
end

I no longer recieve any errors

You are typing "AddMoney" in your OnNPCKilled functions, it has to be addMoney.

Also, use darkrpmodification and don't make your modules in the darkrp gamemode.

You have to check if the killer is a player before giving them money, and the method is addMoney with a lower-case "a". Your error shows that, but your code has AddMoney. Also, use elseif for the class checks.

Shouldn't this be in a hook? And that error doesn't line up with your code. The "A" in "AddMoney" is capitalized in your code but not in the error.

It should be the same thing, but what he's doing is overwriting the gamemode's default OnNPCKilled function.

He should be using hook.Add instead.

So instead of function i should put hook.Add?
