invalid argument #2 (Vector3 expected, got nil) I'm getting this how to I fix it?

Asked by 3 months ago
local rp = game:GetService("ReplicatedStorage")
local Sword = rp:WaitForChild("Sword")

local cframes = {
    ["Right Arm"] = CFrame.new(0,-1,0),
    ["Right Hand"] = CFrame.new(0,0,0)
}

Sword.OnServerEvent:Connect(function(Player,isEquipped)
    local Character = Player.Character
    local Humanoid = Character.Humanoid

    if isEquipped then
        --Equipping the sword
        local Katana = Character:FindFirstChild("Katana")
        if Katana then
            local SideWeld = Katana.PrimaryPart:FindFirstChild("SideWeld")
            if SideWeld then
                SideWeld:Destroy()

                if Humanoid.RigType == Enum.HumanoidRigType.R15 then
                    Katana:SetPrimaryPartCFrame(Character:WaitForChild("RightHand").CFrame * cframes.RightHand)
                elseif Humanoid.RigType == Enum.HumanoidRigType.R6 then
                    Katana:SetPrimaryPartCFrame(Character:WaitForChild("Right Arm").CFrame * cframes["Right Arm"])

                end

                local HandWeld = Instance.new("ManualWeld")
                HandWeld.Part0 = Katana.PrimaryPart

                if Humanoid.RigType == Enum.HumanoidRigType.R15 then
                    HandWeld.Part1 = Character:WaitForChild("Righthand") -- this is the errored line
                elseif Humanoid.RigType == Enum.HumanoidRigType.R6 then
                    HandWeld.Part1 = Character:WaitForChild("Right Arm")
                end

                HandWeld.C0 = > HandWeld.Part0.CFrame:ToObjectSpace(HandWeld.Part1.CFrame)
                HandWeld.Parent = HandWeld.Part0

            end
        end
    elseif not isEquipped then
        --Unequipping the sword


    end

end)

Note: This problem only happens in R15 and I want the game to be compatible with both R15 and R6

When you're looking at it use the view source button as it makes it easier to read because it's not cut off then. LiamQ926 4 — 3mo

In line 22, you’re trying to find RightHand in a table called cframes. But “RightHand” does not exist in that table because the Right Hand in the table has a space between. You either change that line to

Katana:SetPrimaryPartCFrame(Character:WaitForChild("RightHand").CFrame * cframes[“Right Hand”])

or change the table to

local cframes = {
    ["Right Arm"] = CFrame.new(0,-1,0),
    ["RightHand"] = CFrame.new(0,0,0)
}

and for the “errored line” simply change it to

HandWeld.Part1 = Character:WaitForChild("RightHand")

because you typed the H as a lowercase, which can cause errors.

Also I highly recommend to use Tool.Equiped and Tool.Unequipped inside of the tool instead.
