Instant coroutine ?

Hello!

I try to start an empty coroutine for a design reason. I can't find a way to execute that coroutine without wait until the next frame to execute the next part of my code.

There is a sample code (the Execute() method is started with the StartCoroutine() method) :

Code (CSharp):

1. public override IEnumerator Execute() {
2.  
3.             Debug.Log("test2");
4.  
5.             // Node controllable
6.             INodeControllable nodeControllable = item.GetComponent<INodeControllable>();
7.             if (nodeControllable != null) {
8.                 yield return StartCoroutine(Execute(nodeControllable));
9.             }
10.  
11.             Debug.Log("test3");
12.  
13. }
14.  
15. protected virtual IEnumerator Execute(INodeControllable node) {
16.             yield break;
17. }

What I want is when a class doesn't override the Execute method, "test2" and "test3" are logs in the same frame.

Is there something i'm missing here ?

Thanks!

 

You'll need to manually run your inner coroutine:

Code (csharp):

1. if (nodeControllable != null) {
2.     var innerRoutine = Execute(nodeControllable());
3.     while(innerRotuine.MoveNext())
4.         yield return innerRotuine.Current;
5. }

An IEnumerator that hits yield break on it's first MoveNext will return false, so your while-loop will never run and nothing will be yielded by it.

 

Hi Baste!

Thanks for the tip it's working really great.
