Function waits a bit after brick is touched?

Asked Apr 4, 2018263 views3 answers

Hi, I have a script in a brick that's supposed to make a sound play when the brick is touched by the player. It looks like this:

local SP = script.Parent

function onTouch(hit)
	local H = hit.Parent:FindFirstChild("Humanoid")
	if H ~= nil then
		SP.S:Play()
	end
end
	
	script.Parent.Touched:connect(onTouch)

The problem is, I can't find a way to make it wait a little while after touched to perform the action again. The sound plays repeatedly so long as the player is touching the brick. I thought the obvious solution was to add a wait() after when the sound plays, but that didn't work, nor did making it wait until the player is finished touching it to execute again. It may be a simple answer, but how can I fix this?

Thank you to everyone who answered! I had no idea about the debounce function.

Hi SuperJumpman12,

This problem can be easily solved by using a debounce. You basically set a boolean value in the function and check for it at the beginning of the .Touched function. So, if that boolean value is a certain value, then the rest of the function runs, otherwise it won't run. Here, it's easier if I just demonstrate it.

local SP = script.Parent
local deb = false;
local S = SP.S; -- The sound I assume.

function onTouch(hit)
    if deb then return end

    deb = true;
    local H = hit.Parent:FindFirstChild("Humanoid")
    if H ~= nil then
        S:Play()
    end
end

script.Parent.Touched:connect(onTouch)
--[[
	Now, I'm going to set deb back to false when the sound's .Stopped event is run. You can use various other methods to get deb back to false, such as making a wait of the amount of time it takes to play the song, and then setting deb back to false but, I think using this method is the best since it's not complicated at all, seems better organized and efficient-enough. 
--]]

S.Stopped:Connect(function()
	deb = false; -- Sets deb back to false so that the function can run once again.
end);

###If you don't want to use the .Stopped event, you can just add a wait in the function as a cooldown. Here, I will show you below how to do that in the function.

local SP = script.Parent
local deb = false;
local S = SP.S; -- The sound I assume.

function onTouch(hit)
    if deb then return end

    deb = true;
    local H = hit.Parent:FindFirstChild("Humanoid")
    if H ~= nil then
        S:Play()
    end

     wait(S.TimeLength);
     deb = false;
end



script.Parent.Touched:connect(onTouch)

##Well, I hope I helped and have a wonderful day/night.

Thanks,

Best regards,

Debounce.

local debounce = false
local SP = script.Parent

function onTouch(hit)
	if debounce then return end
	debounce = true
	local H = hit.Parent:FindFirstChild("Humanoid")
	if H ~= nil then
		SP.S:Play()
	end
	wait(1) -- Change this to how long you want the cooldown to last for.
	debounce = false
end

script.Parent.Touched:Connect(onTouch) -- connect is deprecated; use Connect.

local SP=script.Parent
local Buffer=false
function onTouch(hit)
	local H=hit.Parent:FindFirstCHild("Humanoid")
	if H and Buffer==false then
		SP.S:Play()
		Buffer=true
		SP.S.Ended:connect(function()
			Buffer=false
		end)
	end
end

Try this. Didn't test it, let me know if it works.

Btw, this will only allow the sound to play again after it is fully finished played (so it will never overlap).
