How can i create Garbage Collection Module?

Help and Feedback Scripting Support
#1

Today i made topic and one guy explained me i should use GC module such as maid or janitor, but i want to make it myself and understand how they work, can anyone explain me and eventually give example of one? because i need to know how to clear instances with multiple references and ect.

thx for help.

Start by defining the module and a table to hold tasks, then create a method to add tasks to the module. Tasks can be any object or function that needs to be cleaned up, define a method to clean up all tasks. This method will loop through the tasks and do the cleanup.

Why not just use Maid or Janitor as the examples? They’re both open source and you can use it as a reference to make your own.

I want to make it myself, also i want to know more… universal way and simplier one because those modules use it in their style

#5

thx. idk if you can, but can you write me a example code for function like that? i better understand when i read the code, it can be simple, i want only basic understanding of it

Yes, i was writing an example for you

That’s the module that handles everything:

local GCModule = {}
GCModule.__index = GCModule

function GCModule.new()
    local self = setmetatable({}, GCModule)
    self.tasks = {}
    return self
end

function GCModule:Add(task)
    table.insert(self.tasks, task)
end

function GCModule:Cleanup()
    for _, task in ipairs(self.tasks) do
        if typeof(task) == "RBXScriptConnection" then
            task:Disconnect()
        elseif typeof(task) == "Instance" then
            task:Destroy()
        elseif type(task) == "function" then
            task()
        end
    end
    self.tasks = {}
end

return GCModule

you can use it like this:

local GCModule = require(path to GCModule)

local gc = GCModule.new()

local connection = game:GetService("RunService").Stepped:Connect(function()
    print("Running")
end)

gc:Add(connection)

local part = Instance.new("Part")
part.Parent = workspace

gc:Add(part)

gc:Cleanup()
