本文实例为大家分享了Unity实现引导页效果的具体代码，供大家参考，具体内容如下

效果图:

1、创建Canvas，设置RenderMode=ScreenSpace-Overlay，UIScaleMode = ScaleWithScreenSize，
ReferenceResolution（x=1080,y=1920）

2、创建一个RawImage，命名为（parentGoImg），并做如下设置

3、在parentGoImg下建几个RawImage，赋予想展示的图片，并做如下设置

4、添加如下脚本给parentGoImg

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{ /// <summary> /// 可移动的最大最小X轴坐标 /// </summary> private float minX, maxX; /// <summary> /// 开始触摸时，算出偏移值，防止跳变 /// </summary> private float offsetX; /// <summary> /// 灵敏度 /// </summary> private float sensitivityX; /// <summary> /// 当前显示第几页 /// </summary> 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); }}

运行即可看到效果
