How would you make a script loop? [closed]

I'm sort of lost on the idea of how to make for example a game or minigame script that will continue to loop itself. I've been trying to figure out loops and I don't think while true do is the most efficient way to loop my game script. Any ideas on how I can loop my script better?

If you want an unconditional infinite loop, while true do .. end is actually the way to go.

Inside, you can use the wait method of Events to avoid having to utilize busy waits, for increased efficiency:

1while true do
2    script.Parent.Touched:wait() --lowercase 'w' ":Wait()" will error
3    print("script.Parent was Touched!")
4end

If you ever run into a case of having to use some kind of busy wait:

1while not script:FindFirstChild("LocalManager") do
2    wait()
3end

Try and script to avoid that:

1while not script:FindFirstChild("LocalManager") do
2    script.ChildAdded:wait()
3end

And if you can't figure out how to do that, by all means ask here.

(In this case, you could just use WaitForChild, but this is the best example of this I could think of right now. I'd actually be surprised if this wasn't the code for WaitForChild internally.)

Ah, I didn't know that. Thank you for the help, it works! :) TofuBytes 500 — 10y

Unconditional is a misnomer. There's still a conditional expression here, it's just that it always evaluates to true. So I guess it's an unconditional conditional loop? blocco 185 — 10y

Fair point. "while true do" is an uncoditional infinite loop, because the condition is 'true' regardless of state. "while someVar do" would then be a conditional infinite loop, so long as someVar is 'true' or truthy, which cannot be garuanteed. adark 5487 — 10y

1while wait() do
2print("Hi")
3end

This will print "Hi" endlessly.
