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);
	}
