Touch function won't work after the first time

#1

Hello! I am trying to make a touch function but after the first time it stops. I tried a while loop and still did not work. Thank you.

local block = script.Parent
local debounce = true
local animation = block.Animation


local function hitFunction(hit)
	local humanoid = hit.Parent:FindFirstChildWhichIsA("Humanoid")
	local anim = humanoid:LoadAnimation(animation)
	if humanoid and debounce == true then
		debounce = false
		local weld = Instance.new("Weld")
		weld.Parent = block
		weld.Part0 = block
		weld.Part1 = hit.Parent:WaitForChild("HumanoidRootPart")
			
		task.wait(4)
		weld:Destroy()
	end
end

block.Touched:Connect(hitFunction)

Yes, because you forgot to bounce = true

local block = script.Parent
local debounce = true
local animation = block.Animation


local function hitFunction(hit)
	local humanoid = hit.Parent:FindFirstChildWhichIsA("Humanoid")
	local anim = humanoid:LoadAnimation(animation)
	if humanoid and debounce == true then
		debounce = false
		local weld = Instance.new("Weld")
		weld.Parent = block
		weld.Part0 = block
		weld.Part1 = hit.Parent:WaitForChild("HumanoidRootPart")

		task.wait(4)
		weld:Destroy()
		
		task.wait(1)
		debounce = true
	end
end

block.Touched:Connect(hitFunction)

I was thinking the same thing, thanks.

local players = game:GetService("Players")

local block = script.Parent

local debounce = false

local function onTouched(hit)
	if debounce then
		return
	end
	
	local hitModel = hit:FindFirstAncestorOfClass("Model")
	if hitModel then
		local hitPlayer = players:GetPlayerFromCharacter(hitModel)
		if hitPlayer then
			debounce = true
			local hitHRP = hitModel:FindFirstChild("HumanoidRootPart")
			local weld = Instance.new("Weld")
			weld.Part0 = block
			weld.Part1 = hitHRP
			weld.Parent = block
			task.wait(4)
			weld:Destroy()
			debounce = false
		end
	end
end

block.Touched:Connect(onTouched)

Debounce fix as mentioned, you probably want to do the debounce check immediately (such that the function can be returned out of without performing any unnecessary preliminary checks). I’ve also made it so that the player’s character’s accessory handles are checked as well as its limbs (only the limbs were checked previously).
