Yield Coroutine error

Archived Forums Questions & Answers

So I’ve been getting some help on Unity Answers about inputting yield and coroutines in my code. (Yield Script Update Error - Questions & Answers - Unity Discussions)

Right now, the start of my code looks like this.

	void Start ()
	{
		OSCHandler.Instance.Init ();
		servers = new Dictionary<string, ServerLog> (); 
		particleSystem.emissionRate = 0;
		 StartCoroutine(BongoClap());
	}
	
	
	IEnumerator BongoClap () {
	while (true) {
        // Rest of my code...

However, now I’m getting an error.

Assets/Scripts/UnityOSC-master/BoncoClapScript.cs(78,51): error CS0019: Operator ||' cannot be applied to operands of type bool’ and `UnityEngine.KeyCode’

It seems to be having a problem with the || operators in this line of code…

	if (Input.GetKeyDown (KeyCode.JoystickButton0) || (KeyCode.JoystickButton1) || (KeyCode.JoystickButton2) || (KeyCode.JoystickButton3)) {
						yield return new WaitForSeconds(5.0f);
     
					yield return null;
					}

Any idea why this might be happening? :S

You need an Input.GetKeyDown around the or condition:

 if (Input.GetKeyDown (KeyCode.JoystickButton0) || Input.GetKeyDown(KeyCode.JoystickButton1) ||  Input.GetKeyDown(KeyCode.JoystickButton2) || (KeyCode.JoystickButton3))

Okay... Now I'm confused. I input that small change of code and now every time I run Play, Unity doesn't work... At all. No errors or anything. Unity just freezes indefintely and stops working. It's definitely an issue with the code I have now because I saved a copy of the code I had before I began using coroutines and it works fine. I'm not sure what is so game breaking about this code. It seems to make sense...

You've got the yield return null in the wrong place probably. To be absolutely sure, put it right at the top of the while(true) loop. the first statement.

It works! Thank you so much! :)
