Memory is through the roof. What should I change?

Module Script:

local module = {}

What should I change in my code to make the memory go down? Should I disconnect function? Is that all? The code works and all, just it’s not the best on memory.

@Infuriashon

while true do
		for i = 1, 100 do
			wait()
			workspace.SmilingKidWithRope:SetPrimaryPartCFrame(CFrame.new(workspace.SmilingKidWithRope.PrimaryPart.Position + Vector3.new(0,-1,0)))
		end
		break
	end

This is absolubtly dumb.
Making a for loop and breaking it to run once?
Then don’t do loop /:

[Vargogram (Muffins)]

So what should I specifically change? Also, I’m new to the business if you haven’t already noticed. So I’m gonna do some dumb stuff before I do smart stuff.

Edit: Get rid of while loop??? Also most of this code was written a bit ago. I’ve learned more things since then.

Memory issues come from many different places within a game.
To determine it is in fact your code, please press F9 go to the Scripts section.
Send a screenshot of where you see your server script activities. General rule of thumb is that anything over 3% needs looking into.

[Vargogram (Muffins)]

The StoryScript(server script, didn’t sent it though.) isn’t hitting high numbers at all. But ‘Main’ is hitting 4% - 5% consistently. What is main? Is that on the client or something else?

[megukoo]

Those should be the name of your scripts. Whatever “Main” is doing is somewhat intensive work.
I also advise checking out the “Memory Management Tips” here to further optimize your game.

[Vargogram (Muffins)]

I can’t find Main anywhere. I even searched it up and nothing pops up for me. Do you have any idea what this means? Maybe main is all the Server Script or something. Plus, there’s no way to differ between Client and Server in the Scripts section.

[megukoo]

Could you show me a screenshot of it?
Also, my apologies. Client script information is not included there. Are you feeling a lot of work is being done there?

[Vargogram (Muffins)]

I figured out that it’s happening with the Server and the Client. They both have the same memory issues. I would screenshot, but it goes to my clipboard. Then I try to send it to the DevForum but I cant find the saved screenshot anywhere.

[Vargogram (Muffins)]

@megukoo I searched up main again, but this time I found ‘ChatMain.’ It’s a local script inside of Chat that enables bubble chat. Could this be it? I personally don’t think so, but it’s possible.

[megukoo]

Shouldn’t be ChatMain.
Since you don’t seem to be able to pinpoint the script, I’d suggest raising some of the intervals in the module script (to say 1 second.) See how it affects performance then.

[greatneil80 (NilOfNils)]

If you join then start lagging over time then you have memory leaks, this could be due to something like this:

while true do wait()
    local newvariable = true
end

You gotta destroy the reference because millions of references will exist

newvariable = nil

if you just lag from the start then either it is your computer or…
you have viruses or a ton of data in the game

[Autterfly]

That’s not quite how it works. When the code reaches where the end would be, the reference to the variable would be gone. Manually assigning var = nil is not necessary when the scope will be terminated.

[greatneil80 (NilOfNils)]

then how does memory leaks work, would it just be events that don’t disconnect. Thanks for the new information.

[Autterfly]

Events and such are handled by Roblox. An event can’t be garbage collected while it’s still connected, but an event can only be disconnected by you (or calling :Destroy() on the object).

Memory leaks in Lua might happen, for example, when there’s a table used in an event that keeps being added into. Since the event won’t GC, and the table will stick around for as long as the event does, any new items added to the table without previous being removed will add to the memory footprint.

There are many ways, but in general you won’t find the issue from variables that get used and thrown around in temporary scopes. Also, booleans, numbers and nil don’t allocate memory in the sense strings or tables do.

[Vargogram (Muffins)]

I have some function modules. Does that take up some memory? Also, how would I connect a function that I can reuse without taking much memory?

[angrybino]

function module.SmilingKidFalls()
	while true do
		for i = 1, 100 do
			wait()
			workspace.SmilingKidWithRope:SetPrimaryPartCFrame(CFrame.new(workspace.SmilingKidWithRope.PrimaryPart.Position + Vector3.new(0,-1,0)))
		end
		break
	end
end

Is very bad, you can break a for loop without having to use a while loop since it will waste resources.

for i  = 0, 10, 0 do
      print(i)
      break -- will break the first time it prints i
end

Also use workspace instead of game.Workspace since you the script won’t have to index game first.

@Infuriashon

while wait(interval) do
		game.Lighting.ClockTime =  game.Lighting.ClockTime + change
		if game.Lighting:GetMinutesAfterMidnight() > 22 * 60  then
			break
		end
	end

This is a perfect example of the While Wait Do idiom. Your code could be rewritten like

repeat
  wait(interval)
  game.Lighting.ClockTime =  game.Lighting.ClockTime + change
until game.Lighting:GetMinutesAfterMidnight() > 22 * 60

Notice the use of repeat ... until instead of while ... do? This is because we want to check for the condition after the body has ran. Which should produce the exact same result as your original code.
