实现引导页效果的具体代码，新手必看！！

本文实例给大家分享了Unity中实现开机页效果的具体代码，供大家参考。 具体内容如下

渲染：

1、创建canvas，设置rendermode=screenspace-overlayunity赋予物体初速度unity赋予物体初速度2d游戏素材，uiscalemode=scalewithscreensize，

参考分辨率(x=1080,y=1920)

2、创建rawimage，命名为（parentgoimg），并进行以下设置

3.在parentgoimg下创建几张rawimage，指定要显示的图片音乐音效，并进行如下设置

4.在parentgoimg中添加以下脚本

using system.collections;
using system.collections.generic;
using unityengine;
using unityengine.eventsystems;
using dg.tweening;
using unityengine.ui;
public class asd : monobehaviour,ibegindraghandler, idraghandler,ienddraghandler
{
  /// 

  /// 可移动的最大最小x轴坐标
  /// 
  private float minx, maxx;
  /// 

  /// 开始触摸时，算出偏移值，防止跳变
  /// 
  private float offsetx;
  /// 

  /// 灵敏度
  /// 
  private float sensitivityx;
  /// 

  /// 当前显示第几页
  /// 
  private int currentshowindex = 1;
  private void start()
  {
    (transform as recttransform).pivot = new vector2(0, 0.5f);
    debug.log(screen.width + "  " + screen.height);
    for (int i = 0; i < transform.childcount; i++)
    {
      (transform.getchild(i) as recttransform).sizedelta = new vector2(0, 0);
      //canvas的rendermode要设置成overlay形式
      //这里i*1080是因为canvas的uiscalemode设置成了scalewithscreensize，resolution为x=1080,y=1920
      //如果canvas的uiscalemode设置成constantpixelsize则吧这里的i*1080改成i*screen.width
      (transform.getchild(i) as recttransform).anchoredposition = new vector2(i * 1080.0f, 0);
    }
    minx = -((transform.childcount - 1) * screen.width);
    maxx = 0.0f;
    //如果移动超过页面的五分之一，则切换页面
    sensitivityx = screen.width / 5;
  }
  public void onbegindrag(pointereventdata eventdata)
  {
    offsetx = transform.position.x - input.mouseposition.x;
  }
  public void ondrag(pointereventdata eventdata)
  {
    //将物体坐标限制在最大最小x轴坐标内
    transform.position = new vector2(input.mouseposition.x + offsetx, transform.position.y);
    if (transform.position.x <= minx)
    {
      transform.position = new vector2(minx, transform.position.y);
    }
    else if (transform.position.x >= maxx)
    {
      transform.position = new vector2(maxx, transform.position.y);
    }
  }
  public void onenddrag(pointereventdata eventdata)
  {
    //判断坐标，是否需要切换页面
    if (transform.position.x > getleftx())
    {
      currentshowindex--;
    }
    else if (transform.position.x < getrightx())
    {
      currentshowindex++;
    }
    transform.domovex(-(currentshowindex - 1) * screen.width, 0.2f);
  }
  float getleftx() {
    return -((currentshowindex - 1) * screen.width - sensitivityx);
  }
  float getrightx() {
    return -((currentshowindex - 1) * screen.width + sensitivityx);
  }
}

运行一下就可以看到效果了
