Is it possible to detect if a player already has a gui?

Asked by 13 days ago

So basically I made a part that on touched gives you a gui, but if you keep touching it you keep getting the gui. Is it possible to make it so it detects if you already have the gui. As from what I have seen the server even with knowing who the player is cannot see what gui they have

You can add some lines of code that verifies so that if the player already has the GUI the function won't fire

local players = game:GetService("Players")
local part = script.Parent
local GUI = part:WaitForChild("YourGUI") --//Pretend the GUI is located there

local function onTouched(hit)
    local humanoid = hit.Parent:FindFirstChild("Humanoid")

    if humanoid then --//Checks if it has a humanoid
        local playerName = hit.Parent.Name
        local sPlayer = players:WaitForChild(playerName)
        local playerGui = sPlayer:WaitForChild("PlayerGui")

        if playerGui:FindFirstChild("YourGUI") then return end --//Checks if the GUI is already at the player's screen, if true then return end

        local newGUI = GUI:Clone()
        newGUI.Parent = playerGui --//Clones the GUI to the player's screen
    end
end

part.Touched:Connect(onTouched)

This is the first solution that came into my head, warn me if any error pops up
