Coroutine

Description

MonoBehaviour.StartCoroutine returns a Coroutine. Instances of this class are only used to reference these coroutines and do not hold any exposed properties or functions.

A coroutine is a function that can suspend its execution (yield) until the given given YieldInstruction finishes.

// - prints "Starting 0.0"
// - prints "WaitAndPrint 5.0"
// - prints "Done 5.0"

function Start() {
    print ("Starting " + Time.time);
    // Start function WaitAndPrint as a coroutine
    yield WaitAndPrint();
    print ("Done " + Time.time);
}

function WaitAndPrint () {
    // suspend execution for 5 seconds
    yield WaitForSeconds (5);
    print ("WaitAndPrint "+ Time.time);
}

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    IEnumerator WaitAndPrint()
    {
        // suspend execution for 5 seconds
        yield return new WaitForSeconds(5);
        print("WaitAndPrint " + Time.time);
    }

    IEnumerator Start()
    {
        print("Starting " + Time.time);

        // Start function WaitAndPrint as a coroutine
        yield return StartCoroutine("WaitAndPrint");
        print("Done " + Time.time);
    }
