How to detect if button is held down?

[pasje1312]

So I made an upgrade button and when you click it it fires an event, but I also want it to click really fast after holding for one second. This is my script:

local replicatedStorage = game:GetService("ReplicatedStorage")
local upgradeEvent = replicatedStorage:WaitForChild("RemoteEvents"):WaitForChild("UpgradeRemoteEvent")
local upgrade = "LuckUpgrade"
local upgradeButton = script.Parent

upgradeButton.MouseButton1Up:Connect(function()
	upgradeEvent:FireServer(upgrade)
end)

please help me!

MouseButton1Up

There is also a ButtonDown … between the two you can tell they are holding it.

--keys
local player = game.Players.LocalPlayer
local userInputService = game:GetService("UserInputService")

local keyToCheck = Enum.KeyCode.Space

if userInputService:IsKeyDown(keyToCheck) then
    print("Space key is currently held down")
elseif userInputService:IsKeyUp(keyToCheck) then
    print("Space key is currently up")
end

--mouse
local player = game.Players.LocalPlayer
local userInputService = game:GetService("UserInputService")

local mouseButtonToCheck = Enum.UserInputType.MouseButton1button

if userInputService:IsMouseButtonPressed(mouseButtonToCheck) then
    print("Mouse button is currently held down")
elseif userInputService:IsMouseButtonReleased(mouseButtonToCheck) then
    print("Mouse button is currently released")
end

Hello! I’ve actually had something similar to this where I tried to detect if the button is held down from this post:

Camera movement not moving repeatedly when holding down a certain arrow key

Hello Developers! I’ve created a Local-Script under StarterCharacter called “2DCameraMovment”. The script function is to replicate those games where rather than the camera following your character, it allows you to simply move your camera freely, such as Lobotomy Corporation. The issue? It has to do with the camera move functions, it does move the camera, although it doesn’t repeatedly move while it’s corresponding arrow key is pressed. (For example, if I press the Left Arrow Key, the camera mo…

Anyway, as @metatablecatmaid said, use UserInputService:IsKeyDown in a repeat loop to check if the key is being held. Also, add this:

repeat
  -- camera code
  task.wait()
until not UserInputService:IsKeyDown(Enum.KeyCode.A)

Sorry if it’s a bit sloppy.

You can make use of MouseButton1Down (which detects when the player holds down their mouse) like this:

upgradeButton.MouseButton1Down:Connect(function()
	local isHeldDown = false 
	upgradeButton.MouseButton1Up:Once(function() 
		-- Once disconnects the function after one time to prevent memory leaks
		upgradeEvent:FireServer(upgrade)
		isHeldDown = false -- no longer held down
	end)

	task.wait(1)
	if isHeldDown == false then return end -- stop if player stopped holding
	while isHeldDown == true do
-- spam the event here
end
end)

The reason why I put MouseButton1Up into the MouseButton1Down function is to prevent the code from running when the player clicks and holds their mouse again within the 1 second time frame, causing multiple runs

For the post above: the 1 second wait is the problem so it might not fit in this problem (I may be wrong though)

one question though, wat does return end mean in if isHeldDown == false then return end

[neweve2323 (block)]

It stops the function from continuing
I may not be the best at explaining this though

Your solution will lead to being locked in an endless loop … Try this.

local db=true
local isHeldDown = false
upgradeButton.MouseButton1Down:Connect(function()
	if db then db = false
		isHeldDown = true 

		while isHeldDown == true do task.wait(0.33)
			if isHeldDown == false then db=true
				break
			end
		end
	end
end)

upgradeButton.MouseButton1Up:Once(function() 
	upgradeEvent:FireServer(upgrade)
	isHeldDown = false
end)

Also it seems in this case you really don’t even need the down part just the up …

upgradeButton.MouseButton1Up:Once(function() 
	upgradeEvent:FireServer(upgrade)
end)
