Please read my post above or what HighQualityCrystal said. It explains everything you need to do. Create a LocalScript inside any of the LocalPlayer’s accessible places or what you wanna call them. StarterPlayer, StarterCharacterScripts, StarterPlayerScripts, StarterGui or StarterPack but you need to assign what part you need to touch in order to fire the script.
local played = false
workspace:FindFirstChild("*Your Part Name Here*").Touched:Connect(function()
if not played then
workspace.SoundLibrary.Scream:Play()
played = true
wait(5)
played = false
end
end)
