C# yield not working.

Questions & Answers

I am making a reload time, but when I start a coroutine, it doesn’t wait for 3 seconds and then reloads. Here is my code:

void Update(){

if(ammoInClip == 0){
		StartCoroutine("reload", 3f);
		ammoInClip = 30;
	}

}

IEnumerator reload(float wait){
		yield return new WaitForSeconds (wait);
	}

The problem happens because when you yield, you immediately return the control to the Update method. It then executes the ammoInClip = 30. After 3 seconds, the control returns to Reload - that does nothing.

That’s why you have to put ammoInClip = 30 after the yield, so it can return the control to the Update method, continue the game and come back after 3 seconds to reload.

void Update(){
    if(ammoInClip == 0){
       StartCoroutine(Reload(3f));
    }
}

IEnumerator Reload(float wait){
   yield return new WaitForSeconds (wait);
   ammoInClip = 30;
}

Note the call for StartCoroutine, I’m not using a string, better for type-safety.

Do you come from Java? Methods in C# usually starts with lowercase :slight_smile:

With the use of code and whenever you want to StartCoroutine that has require the method name and its argument if you have passed.

void Update(){
    if(ammoInClip == 0){
      StartCoroutine(reload(3.0f));
      ammoInClip = 30;
    }

}

IEnumerator reload(float wait){
   yield return new WaitForSeconds (wait);
}
