unity协程

下面一段小代码是通过一定的延迟,把脚本的挂载物体变为蓝色

 1     public float f;
 2     void Update()
 3     {
 4         if (Input.GetKeyDown(KeyCode.W))
 5         {
 6             StartCoroutine("Fade");
 7         }
 8     }
 9     IEnumerator Fade()
10     {
11         for (f = 0f; f<=1f; f +=0.1f)
12         {
13 
14             this.GetComponent<MeshRenderer>().material.color = new Color(0,0,f);
15             yield return new WaitForSeconds(.5f);//延迟
16         }
17     }
