how do i fix Argument 1 missing or nil?

Asked by 6 days ago

I am new to making UI in Roblox studio and I am trying to make a ring from sonic. what is supposed to happen is that when you touch the ring it will fire a remote event that it will fire a remote event that will update the text label however when i touch the ring the " Argument 1 missing or nil" error message appears.

This is my script which is a child on the ring:

local ring = script.Parent
local ringSparkle = ring.ParticleEmitter
      ringSparkle.Enabled = false
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local ringUpdate = ReplicatedStorage:WaitForChild("ringCountUpdate")
function destroy(otherPart)
    local partParent = otherPart.Parent
    local humanoid = partParent:FindFirstChild("Humanoid")
    if humanoid then
        ring.Transparency = 1
        ring.CanCollide = false
        ringSparkle.Enabled = true
        wait(1)
        ring:Destroy()
        ringUpdate:FireClient()
    end
end

ring.Touched:Connect(destroy)

and this is my text label local script

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local ringUpdate = ReplicatedStorage:WaitForChild("ringCountUpdate")


local ringCount = script.Parent
local ringCountInt = 0
ringCount.Text = tostring(ringCountInt)

local function addRing ()
    ringCountInt += 1
    ringCount.Text = tostring(ringCountInt)
end

ringUpdate.OnClientEvent:Connect(addRing)

The FireClient function must always include a player as it’s first argument, otherwise it won’t send to the the client. To get the player from a character, you use Players:GetPlayerFromCharacter(CharacterModel).

local ring = script.Parent
local ringSparkle = ring.ParticleEmitter
ringSparkle.Enabled = false
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local ringUpdate = ReplicatedStorage:WaitForChild("ringCountUpdate")
function destroy(otherPart)
    local partParent = otherPart.Parent
    local humanoid = partParent:FindFirstChild("Humanoid")
    local playerFromCharacter = game:GetService("Players"):GetPlayerFromCharacter(partParent)
    if partParent and humanoid and playerFromCharacter then
        ring.Transparency = 1
        ring.CanCollide = false
        ringSparkle.Enabled = true
        task.wait(1)
        ring:Destroy()
        ringUpdate:FireClient(playerFromCharacter)
    end
end

ring.Touched:Connect(destroy)
