下边是Shader代码：

// Upgrade NOTE: replaced 'mul(UNITY_MATRIX_MVP,*)' with 'UnityObjectToClipPos(*)'

下面是UI代码：

using System.Collections;
using UnityEngine;
using UnityEngine.UI;

  private GameObject Plane;
  private Material m_Material;
  private Coroutine effect;
  private Image LeftPage;
  private Image RightPage;
  private void Awake()
  {
    InitUI();
  }
  public override void InitUI()
  {
    Plane = GetGameObject("Plane");
    LeftPage = GetComp("LeftPage");
    RightPage = GetComp("RightPage");
    Plane.SetActive(false);
    m_Material = Plane.GetComponent().material;
  }
  public void PlayPageTurnEffect(bool isLeft = true)
  {
    if (!gameObject.activeSelf)
    {
      return;
    }
    if (effect != null)
    {
      StopCoroutine(effect);
    }
    effect = StartCoroutine(FanShuEffect(0.5f, isLeft));
  }
  public void ShowRightImage(string right)
  {
    RightPage.gameObject.SetActive(true);
    RightPage.sprite = ResourcesMgr.Instance.LoadObj(right);
  }
  public void ShowLeftImage(string left)
  {
    LeftPage.gameObject.SetActive(true);
    LeftPage.sprite = ResourcesMgr.Instance.LoadObj(left);
  }
  private IEnumerator FanShuEffect(float time, bool isLeft)
  {
    LeftPage.gameObject.SetActive(false);
    RightPage.gameObject.SetActive(false);
    Plane.SetActive(true);
    int angle = (int)(180 * 0.1f);
    for (int i = 0; i < 10; i++)
    {
      if (isLeft)
      {
        m_Material.SetFloat("_Angle", angle * i);
      }
      else
      {
        m_Material.SetFloat("_Angle", 180 - angle * i);
      }
      yield return new WaitForSeconds(time * 0.1f);
    }
    if (isLeft)
    {
      m_Material.SetFloat("_Angle", 180);
    }
    else
    {
      m_Material.SetFloat("_Angle", 0);
    }
    Plane.SetActive(false);
    OnEffectOver();
  }
  private void OnEffectOver()
  {
    //--callback
  }
}
