Polling question

Unity Engine
1

I would like to call a function every second or so. It seems the best method for this is to do a StartCoroutine, but I’m unsure if calling StartCoroutine() ‘recursively’ is a bad idea:

	IEnumerator pollForTweetability()
	{
		yield return new WaitForSeconds(1.0f);
		setButtonEnabled(photoController.canUserTweet());
		StartCoroutine(pollForTweetability());
	}

I’m new to Unity and C#. Is this the preferred way to poll and execute code?

You could use the Update function that’s called every frame or second i forgot which one :stuck_out_tongue:

In this instance I’d prefer not to call Update, but I understand that’s an option. Update is called every frame and so its a little CPU-heavy for what I’m doing.

Calling it recursively would be a bad idea, since eventually you’d run out of stack space.

    while (true) {
        yield return new WaitForSeconds(1.0f);
        setButtonEnabled(photoController.canUserTweet());
        StartCoroutine(pollForTweetability())
    }

Or just use InvokeRepeating instead.

Thanks Eric, I don’t know why I didn’t see InvokeRepeating. That is exactly what I’m after!
