What other then a infinite loop causes "hanging code"?

Asked 452 views1 answers

Sometimes, we get this warning or so by Roblox Studio saying that a code has been left hanging for a while telling us to break it. This normally occurs during infinite loops. But the thing is, I did NOT use an infinite loop and I received this warning.

I have 2 question:

What causes "hanging code"?

and

What can be done to fix "hanging code"?

Local Script:

	if Disable then
		Char['Gear Equip Handler'].Disabled = true
		if plr:WaitForChild('PlayerStatus').WeaponEquipped.Value then				 
			RE.EquipGear:FireServer('Weapon') -- Force Unequip
		end

I actually do not know if this is the script that is causing the hanging each time I press play a different line "hangs". (I cut a lot of the script due to too long)

I can't see anything in your code there that would cause any sort of hanging code so it likely is elsewhere. But to answer your question, another way to cause an infinite loop that a lot of time produces no errors is calling a Module Script in a Module Script, that also calls the same Module Script back.

Module1

local module2 = require(game.ServerScriptService.Module2)

Module2

local module1 = require(game.ServerScriptService.Module1)

But on your quest to find places where your code might be creating infinite loops, just look for places that loop. And determine if there is any sort of case where they potentially could never end. For example if you have a recursive like function that never completed. It probably is something that isn't as obvious as while true do end
