how do you fix Argument 1 missing or nil error from egg hatching system?

Asked by 15 days ago

Hope you are having a good day. I am just here to say I have watched Alvinblox's egg hatching system tutorial and I am currently at part 2. There is a new error called "Argument 1 missing or nil" it is at line 60 in the petFollowPlayer script (local pet = game.ReplicatedStorage.HatchablePets:FindFirstChild(petName)) here is the code

petFollowPlayer


local function equipPet(player, pet, petName)
    print(player)
    local character = player.Character
    if pet ~= nil and character ~= nil then
        if character:FindFirstChild(player.Name.."s' pet") then
            character(player.Name.."s' pet"):Destroy()
        end
        if character.HumanoidRootPart:FindFirstChild("attachmentCharacter") then
            character.HumanoidRootPart:FindFirstChild("attachmentCharacter"):Destroy()
        end

You are missing an argument 1. Quick look at the line 60 of Your code reveals that the argument missing is petName.

local pet = game.ReplicatedStorage.HatchablePets:FindFirstChild(petName)

Where is that argument coming from? Going back a little bit, You will find that petName is being passed via a remote event:

game.ReplicatedStorage.equipPet.OnServerEvent:Connect(function(player,petName)

Now this means that the server is not receiving this argument on the event being fired. That means we need to find where the event is being fired on client. By browsing Your local script for a while I have found this fragment:

buttonConnection[#buttonConnection+1] = newTemplate.MouseButton1Click:Connect(function()
        if newTemplate.Equiped.Text == "EQUIPPED" then
            game.ReplicatedStorage.unequipPet:FireServer(pet.Name)
            newTemplate.Equiped.Text = "UNEQUIPPED"
            newTemplate.Equiped.TextColor3 = Color3.fromRGB(255,0,0)
        else
            game.ReplicatedStorage.equipPet:FireServer()
            setTemplateEquipped(newTemplate)
        end
    end)

As you can see, there are 2 events that may be fired here. Equip and unequip. You may notice that while unequip provides the pet name to unequip, equip event does not. You then need to replace this line (36 in You code) with this

game.ReplicatedStorage.equipPet:FireServer(pet.Name)

so that the server knows which pet to equip.

I hope this helps.
