Yield Return New WaitForSeconds() Does Not Work

[GC1983]

Hey all,

So Ive been converting scripts from JS to C#. Ive noticed that if I have a WaitForSeconds() from the JS and try to use it in the C# converted copy, it doesnt do ANYTHING.

if(Input.GetKeyDown("x"))
{	
	//instantiate and roll bomb
	RollBombs();
}

public IEnumerator RollBombs()
	{	
		if(bombsActive)
		{	
			bombsOut++;	
			bombsEach = false;

			if(bombsOut <= 3)
			{			
				rollIsPlaying = true;	
				yield return new WaitForSeconds(player.animation["roll_bomb"].length / 3); 
				rollIsPlaying = false; 
				
			 	Instantiate(bomb, player.transform.position + player.transform.forward * .5f, player.transform.rotation);
				bomb.rigidbody.AddForce(bomb.transform.forward * 10, ForceMode.Impulse);
			}
		}	
	}

I dont get any errors before or after the execution. It just doesnt execute. Something Im missing?

You have to create a Corountine in C# for this.

Replace RollBombs() with StartCoroutine(RollBombs());

More information here : Unity - Scripting API: MonoBehaviour.StartCoroutine

Just i would like to understand the case,because i had the same issue while calling this function

`IEnumerator OpenLevel(string levelToLoad){
	yield return new WaitForSeconds(0.35f);
	Application.LoadLevel(levelToLoad);		
}`

when i used
OpenLevel(“mylevel”) it didn’t work but when i used

and StartCoroutine(OpenLevel(“mylevel”)) it worked

but when i used it in another script inside OnMouseUp() function the yield return worked without any extra work

`IEnumerator OnMouseUp()
{
	yield return new WaitForSeconds(0.35f);
	Application.LoadLevel(levelToLoad);		
}`

any idea why?

You need to call RollBombs in a coroutine.

StartCoroutine(RollBombs());
