Help and Feedback Scripting Support
#1

I have two OOP scripts that work together but the combo object is always printing nil. I don’t understand why though. Thanks for any help.

-- Combo Handling
-- This is inside a player OOP module and self["userid"] is printing correctly
						
						local comboObject = comboModule.getComboMeter(self["UserId"])
						print(self["UserId"])
						print("Hello")
						print(comboObject)
						comboObject:Update(1)

-- Combo Module

local ComboMeter = {}

ComboMeter.__index = ComboMeter

local comboTable = {}



function ComboMeter.new(textLabel, plr)
	local newComboObject = setmetatable({
		ComboNumber = 0,
		Label = textLabel,
		Color = Color3.new(1,1,1)
	}, ComboMeter)
	
	comboTable[tostring(plr.UserId)] = newComboObject
	task.wait(1)
	print(comboTable)
return newComboObject
end

function ComboMeter.getComboMeter(plrId)
	print(comboTable)
	return comboTable[tostring(plrId)]
end

function ComboMeter:Update(amount)
	self["ComboNumber"] += amount
	self["Label"].Text = tostring(self["ComboNumber"])
end


return ComboMeter

The combo object is printing nil because the server and the client each load your ModuleScript in their own Lua VM. The comboTable you fill with ComboMeter.new on the client never exists in the server’s copy, so getComboMeter looks it up in an empty table

Create the ComboMeter for each player in a server script and store it in the server-side comboTable, then just use a RemoteEvent to send the current combo value down to a local script that only updates the text label

Let me know if that works out
