[HELP NEEDED] How to cleanup a plugin?

Help and Feedback Scripting Support
#1

I tried making a plugin, and I keep getting annoying errors from old versions of the plugin
This is the main script:

local core = game:GetService("CoreGui")
local guiF = script.Parent.Parent.Gui

local toolbar = plugin:CreateToolbar("RGB Suite")
local button = toolbar:CreateButton("Open suite", "RGB Suite V0.1", "")

local open = false

script.Parent.Parent.Parent = game.ServerStorage

function on()
	local gui = core:FindFirstChild("RGBSuite")
	gui.Enabled = true
end

function off()
	local gui = core:FindFirstChild("RGBSuite")
	gui.Enabled = false
end

if not core:FindFirstChild("RGBSuite") then
	local cgui = guiF:FindFirstChild("RGBSuite"):Clone()
	cgui.Parent = core
	open = false
end

local function clicked()
	if open == false then
		on()
		open = true
		button:SetActive(true)
	else
		off()
		open = false
		button:SetActive(false)
	end
end

button.Click:Connect(clicked)

plugin.Unloading:Connect(function()
	button:SetActive(false)
	plugin:Deactivate()
	core:FindFirstChild("RGBSuite"):Destroy()
	script.Parent.Parent:Destroy()
end)

The gui itself does get refreshed, but other scripts in the plugin keep erroring because they didnt get removed properly, even though I destroyed the whole plugin folder.

Cleaning up plugins is not explained anywhere, even in the “Intro to plugins” article, so now Im just stuck on what to do about this

How can I solve this?

Observation 1: if the main script parents the whole plugin folder to ServerStorage, it DOES get destroyed when it unloads, but the TextEditor still runs somehow even though its destroyed?

Observation 2: plugin.Unloading doesnt fire when the place closes for some reason

Can you show us the errors in the console?

#3

The error comes from my RichText editor thats in the plugin, its in a widget.
If you select a TextBox or other gui element with text, the script checks if it has RichText checked or unchecked.
If its unchecked, it makes a “Error” Label visible.
This is where the problem comes from, the script works properly, and the label DOES get shown or hidden, but the old code still errors.
It says “Error” is not a valid member of TextBox or infinite yields possible
I can confirm its old code, since the currect script is named “TextEditor”. If I rename it to something else, “TextEditor” would still give errors

#4

Actually, does this happen only for plugins that are saved locally?
I didnt publish this plugin to Roblox, so I dont know if this happens ONLY to saved locally or all plugins

#7

Just updated the topic.
Any help here? There is still no solution

#8

If you dont need the old script just delete it or disable it, do you need that?
I don’t understand why you need to have an old script if you have a new one that does the same functions

Maybe I didn’t understand what you mean

Or just try to fix the code giving the error

#9

If I overwrite the plugin file (when I update the plugin) the old versions of the code still run until I restart studio.
Even if I destroy or disable the old scripts, they still run

I found a basic fix for this, I just did an if statement in most functions:
if script.Parent ~= nil then

And it seems to eliminate the errors, but I dont know if the old script versions still remain somewhere out there, and I dont know what to do with it

#10

oh.
I don’t know what to do with the old versions but you can put a version control, a code that downloads the version number from a pastebin page (or an online database) and checks if it is not the same as the version in use, disabling the plugin

So when you update it just change the new version number in the pastebin page and in the new script to disable the old versions

something like:

local pluginVersion = 1 -- current plugin version
local newVersion = -- download from the pastebin page with Http service

if pluginVersion == tonumber(newVersion) then
    -- Execute the code
else
    print("Update the plugin")
end
