[Untiy]贪吃蛇大作战(二)——规则界面

游戏规则界面:

从界面上可以看出,一共有三个按钮,两个切换按钮和一个退出按钮。

一共三张规则图片Sprite,我们通过设置其是否为Active来控制显示,其控制脚本代码如下:

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

public class changePicture : MonoBehaviour {
    public RawImage bg1, bg2, bg3;
    private static int currentIndex=1;
	public void BackPicture()
    {
       
        --currentIndex;
        if (currentIndex < 1)
            currentIndex = 1;
        switch (currentIndex)
        {
            case 1:
                bg1.gameObject.SetActive(true);
                bg2.gameObject.SetActive(false);
                bg3.gameObject.SetActive(false);
                break;
            case 2:
                bg1.gameObject.SetActive(false);
                bg2.gameObject.SetActive(true);
                bg3.gameObject.SetActive(false);
                break;
            case 3:
                bg1.gameObject.SetActive(false);
                bg2.gameObject.SetActive(false);
                bg3.gameObject.SetActive(true);
                break;
        }
    }
    public void NextPicture()
    {
       
        ++currentIndex;
        if (currentIndex >3)
            currentIndex = 3;
        switch (currentIndex)
        {
            case 1:
                bg1.gameObject.SetActive(true);
                bg2.gameObject.SetActive(false);
                bg3.gameObject.SetActive(false);
                break;
            case 2:
                bg1.gameObject.SetActive(false);
                bg2.gameObject.SetActive(true);
                bg3.gameObject.SetActive(false);
                break;
            case 3:
                bg1.gameObject.SetActive(false);
                bg2.gameObject.SetActive(false);
                bg3.gameObject.SetActive(true);
                break;
        }
    }
}

将对应的三张图片放上去即可。

然后设置好返回界面的跳转(不要忘记canvas的适配哦!)

这一个场景就这样完成了。
