Change a value inside a .Changed function without causing a loop

[arkanooun]

So what this code about is if the resources goes above the max res, for example 300 (from other resources) + 60 (the resources that goes above the max) /320 (the max resources) then the resources that goes above the max will be reduced using this line of code: res.Value = (prevTotalRes + res.Value) - plr.MaxRes.Value but the problem is that the code triggers the .Changed function so it causes a loop, so im asking for help if theres a solution. The full code:

for i, res in pairs(plr.Resources:GetChildren()) do
	if not res:FindFirstChild("FrontFrame") then
		local prevRes = 0
		local prevTotalRes = 0

		res.Changed:Connect(function(val)
			prevTotalRes = totalRes.Value
			totalRes.Value += (val - prevRes)
			prevRes = val

			if totalRes.Value >= plr.MaxRes.Value then
				totalRes.Value = plr.MaxRes.Value
				res.Value = (prevTotalRes + res.Value) - plr.MaxRes.Value
			end
		end)
		
	end
end

Maybe rawset could would work? But i heard its used for tables

Try adding a debounce mechanism so it prevents running the code that changes the value again inside the event.

for i, res in pairs(plr.Resources:GetChildren()) do
	if not res:FindFirstChild("FrontFrame") then
		local prevRes = 0
		local prevTotalRes = 0
		local debounce = false 
		res.Changed:Connect(function(val)
			if debounce then
				return -- value is being changed, stop the function here
			end
			debounce = true 
			prevTotalRes = totalRes.Value
			totalRes.Value += (val - prevRes)
			prevRes = val

			if totalRes.Value >= plr.MaxRes.Value then
				totalRes.Value = plr.MaxRes.Value
				res.Value = (prevTotalRes + res.Value) - plr.MaxRes.Value
			end
			debounce = false
		end)
		
	end
end

ive tried that but still causes it to repeat several times

That technique no longer works with the deferred signal behaviour, (see workspace.SignalBehaviour)

Workaround I found is to put the debounce = false inside of two task.defer()…
Other workaround is to set workspace.SignalBehaviour to immediate (cuz deferred is stupid, thanks roblox)

I have yet to know of an actual solution to this that isn’t a really stupid workaround

Task.defer nested in a task.defer sounds so sacrilegious
