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.
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); } }
