Why GetAttributeChangedSignal Only Run Once?

Help and Feedback Scripting Support
#1

Can anyone explain to me why this only run once? It supposed to fire every time the attribute changes, correct? The attribute is given by the server when you join, and I’ve made sure the name is correct. It does print the “newSpeed” when you join but when it changes again it just stops. Adding a loop doesn’t work.

local plr = game.Players.LocalPlayer
local Character = plr.Character or plr.CharacterAdded:Wait()
local newSpeed = Character:GetAttribute("RunSpeed")

print(Character)

if Character:GetAttributeChangedSignal("RunSpeed") then
	newSpeed = Character:GetAttribute("RunSpeed")
	print(newSpeed)
end

Try turning :GetAttributeChangedSignal() it into a function. That way, it should run every time the attribute is changed.

Character:GetAttributeChangedSignal("RunSpeed"):Connect(function()
	newSpeed = Character:GetAttribute("RunSpeed")
	print(newSpeed)
end)

Sure. You’re not binding that RBXScriptSignal to anything, and it’s truthy in a boolean context, so it passes the if condition.

What do you mean? Isn’t it connect to a function?

Can you show me an example of what that would look like?

Documentation is your best friend:

Just like your plr.CharacterAdded signal, GetAttributeChangedSignal() returns an RBXScriptSignal that fires whenever the passed string changes.

You then Connect that signal to a function like how @J_Angry provided.
