Learning how to use Yield

Questions & Answers
1

Im trying to learn how to use yields and stumbled upon this example. Why wont this works? myMethodYield never prints and I just cant understand why. Isnt yield supposed to do some code, interrupt and come back again later? In this case, if I understood it right, it should come back after 1 frame.

Thank you!

using UnityEngine;
    using System.Collections;
    using System;
    using System.Collections.Generic;
    
    public class FuncAsParamTest : MonoBehaviour 
    {
    	// Use this for initialization
    	void Start () 
        {
    	}
    	
    	// Update is called once per frame
    	void Update () 
        {
            Debug.Log( "Update world" );
            MyClass mc = new MyClass( );
            mc.funcTest( mc.myMethodYield); //never prints
            mc.funcTest( mc.myMethod2);
            mc.myMethodYield(); //never prints
    	}
    
        class MyClass
        {
            public void funcTest( Func<object> methodToRun )
            {
                Debug.Log( "Callig MethodToRun" );
                methodToRun( );
            }
    
            public IEnumerator<object> myMethodYield( )
            {
                Debug.Log( "myMethod - hello world" );
                yield return null;
                Debug.Log( "myMethod - after yield" );
                yield return null;
            }
    
            public object myMethod2( )
            {
                Debug.Log( "myMethod2 - hello world" );
                return 0;
            }
    
        }
    }

You need to call StartCoroutine(mc.myMethodYield()) instead of mc.myMethodYield()
