Since using infinite loops is bad, how can I replace this script?

I've heard on numerous occasions that using while true do loops are bad, so how can I replace this script?

        if script.Parent.TotalAmmo.Value <= 0 then
            while true do
                wait(999999999)
            end
        end

you need to give context. infinite loops aren't necessarily bad; there's an occasion for everything Gey4Jesus69 2705 — 5y

What kind of context do you need? Do you need more of the script? DaBrainlessOne 129 — 5y

Considering 999999999 seconds is almost 32 years, I don't think you need the `while` loop. However, there's still almost certainly a better way to do what you're doing. Please post the rest of the script. fredfishy 833 — 5y

You can probably replace the whole loop with a `return`. fredfishy 833 — 5y

while true do loops aren't necessarily bad, and are actually very commonly used among other programming languages.
However, one thing to note is that in Roblox, you must include a wait() inside non-terminating loops or your game will freeze (known as a hang). This is due to Roblox's task scheduler and how it invokes every function in succession, and if a function doesn't return or doesn't include some kind of yielding (like wait), it won't be able to make a full loop. And thus, cannot render the next frame until it does [which is never].

One alternative to a while true do infinite loop is the RenderStepped function:

game:GetService("RunService").RenderStepped:Connect(function()
    print(workspace.Part.CFrame.LookVector) --it will print the direction "Part" is pointing every tick 
end)

This is a good alternative when trying to constantly check for certain values and update other values throughout the time that the game is running.
