改变Cube的Shader下的Alpha值,实现Cube若隐若现的效果。

 

private float rotaSpeed = 5f;

private float timer = 1;

private bool flag = true;

private float delay = 4.0f;

void Update ()
{
  if (timer <= 0)
  {
    flag = false;
  }
  if (flag == false)
  {
    timer += Time.deltaTime / delay;
  }
  if (timer >= 1)
  {
    flag = true;
  }
  if (flag == true)
  {
    timer -= Time.deltaTime / delay;

  }

  var render = Cube.GetComponent<Renderer>();

  if (render != null)
  {
    var r = render.material.color.r;
    var g = render.material.color.g;
    var b = render.material.color.b;
    render.material.color = new Color(r, g, b, timer);
  }

  //cube自转

  Cube.transform.Rotate(new Vector3(0, -1, 0), Time.deltaTime * rotaSpeed);
}
