A way to prevent dex or other guis that exploiters put in coregui?

Lag might screw them over, Ping and FPS.

Yeah thats the point but it will not kick them it will just decline their touch to the ball

Same thing. Itā€™d give a advantage to people with higher/lower FPS/Ping
Lower FPS and Ping might also give them an advantage too.

is it a possibility that i can check its ping and fps

Wonā€™t make a difference. And still gives them an advantage/disadvantage if it does make a difference.

oh ok then that concludes this then

Mhm. Goodluck in your football game Berk.

Giving a example from my perspective and what Iā€™ve acomplished. You are able to detect Dex in multiple ways though near to all methods are bypassable for exploiters. For example Iā€™ve made a Anti Dex though it is bypassable, I have secured it using Anti Hook Functions. Though it doesnā€™t make it in-bypassable it still secures it to a entirely new level and it really limits the ammount of people that actually can bypass it.

To make it harder for exploiters to remove your client-side anti exploit, use a server script that randomly places the client-side script in the player/character.
Hereā€™s what the code should look like.

local function CloneClientAntiExploit()
            pcall(function()
                local Descendants = Player:GetDescendants()
                table.insert(Descendants, v ) end
                table.remove(Descendants, (table.find(Descendants, Player.PlayerGui)))

                local ClonedAntiExploit = script.AntiExploitLocal:Clone()
                ClonedAntiExploit.Name = HttpService:GenerateGUID(true)
                ClonedAntiExploit.Parent = Descendants[math.random(1, #Descendants)]
                ClonedAntiExploit.Disabled = false
                wait(10)
                ClonedAntiExploit:Destroy()
            end)
        end
        coroutine.resume(coroutine.create(function()
            CloneClientAntiExploit()
            while wait(1) do 
                CloneClientAntiExploit()
            end
        end))
