How to start a Method after Coroutine has finished
Hello,
i have a problem with my Program. The program needs to run several methods and has one recursive method which uses the WaitForSeconds method. Right now the ThirdTask() gets immediately called after SecondTask(). But to run correct the SecondTask must be completed before the ThirdTask(). Has someone an idea how i can solve this problem?
Thank you for your help.
public void MyProgram ()
{
FirstTask ();
SecondTask (int one, int two);
ThirdTask ();
}
public void SecondTask(int one, int two)
{
//Do some stuff first
StartCoroutine(TheCoroutine (int one, int two));
}
private IEnumerator TheCoroutine( int one, int two)
{
case 0:
yield return new WaitForSeconds(0.01f);
yield return StartCoroutine(TheCoroutine (int one, int two));
break;
case 1:
yield return new WaitForSeconds(0.01f);
yield return StartCoroutine(TheCoroutine (int one, int two));
break;
}
You could turn your second task into a coroutine as well so that it can yield and wait for TheCoroutine to finish. After that you can place the call to ThirdTask at the end of SecondTask rather than in the main program so that it is delayed like this:
public void MyProgram ()
{
FirstTask();
StartCoroutine(SecondTask(one, two));
}
public IEnumerator SecondTask(int one, int two)
{
//Do some stuff first
yield return StartCoroutine(TheCoroutine(one, two));
ThirdTask();
}
An ugly way is to put your ThirdTask() at the end of the coroutine from SecondTask()
private IEnumerator TheCoroutine( int one, int two)
{
case 0:
yield return new WaitForSeconds(0.01f);
yield return StartCoroutine(TheCoroutine (int one, int two));
break;
case 1:
yield return new WaitForSeconds(0.01f);
yield return StartCoroutine(TheCoroutine (int one, int two));
break;
}
ThirdTask()
yield return null;
There may be another option though :)
You can pass Action parameter to your coroutine function here, is the sample code.
public class CoroutineDemo : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
StartCoroutine(CoroutineDemonstration(MethodCallAfterCoroutineFinshed));
}
IEnumerator CoroutineDemonstration(Action action)
{
Debug.Log("Coroutine Started");
yield return new WaitForSeconds(2);
Debug.Log("Corouine Ended.");
action();
}
void MethodCallAfterCoroutineFinshed()
{
Debug.Log("Corouine Ended After.");
}
}
Here is the 3-minute explantion.
