I'm trying to make a locked door that when you touch the locked door it plays a sound and enables a GUI saying that its locked, the problem is that when you press it, it tends to spam the sound and GUI.

1script.Parent.Touched:Connect(function(hit)
2if hit.Parent:FindFirstChild("Humanoid")then
3game.ReplicatedStorage.LockedDoor:FireClient(game.Players:GetPlayerFromCharacter(hit.Parent)) 
4end
5end)

^ The script that's in the door.

Howdy!

In the scripting world, we call this "debounce". Don't ask me why, the Code Gods just made it like that. The definition used by this site is:

Debounce is a term that is often associated with the act of adding a cool-down time to a function so it doesn't get called rapidly. This can be especially helpful when used in conjunction with the Touched event of parts. Oftentimes, this is accomplished by setting a variable to true at the beginning of a function, and setting it to false again at the end. Then, at the very beginning of the function, if the variable is already true, then you use the 'return' keyword, effectively ending the function.

Before your function, add a variable called "debounce" and set it to false. Then when the function is ran, set the debounce as true with a wait time of three seconds (or whatever you want). It'll look something like what I have below.

01local Debounce = false
02 
03script.Parent.Touched:Connect(function(hit)
04if hit.Parent:FindFirstChild("Humanoid") and not Debounce then
05Debounce = true
06game.ReplicatedStorage.LockedDoor:FireClient(game.Players:GetPlayerFromCharacter(hit.Parent))
07wait(3)
08Debounce = false
09end
10end)

It still repeats the action a bunch of times with debounce, Uniplier 83 — 4y

I think you do this

01local debounce = false
02 
03script.Parent.Touched:Connect(function(hit)
04 hit.Parent:FindFirstChild(“Humanoid”) then
05  if debounce == false then
06   debounce = true game.ReplicatedStorage.LockedDoor:FireClient(game.Players:GetPlayerFromCharacter(hit.Parent))
07   wait( insert amount of time before door makes sound plus GUI shows up again )
08   debounce = false
09  end
10 end
11end)

hopefully this was helpful and the correct answer

Still didn't work Uniplier 83 — 4y

Maybe if you change the if not debounce then to if debounce == false then 1JBird1 64 — 4y

I’ve edited it so you see how it would look 1JBird1 64 — 4y

It breaks the door and there's a lot of red underlines Uniplier 83 — 4y
