Unity3D_(游戏)卡牌03_选关界面

 

启动屏界面、主菜单界面、选关界面、游戏界面

卡牌01_启动屏界面　　传送门

卡牌02_主菜单界面　　传送门

选关界面效果

　　(鼠标放在不同关卡上显示不同的关卡提示信息，点击关卡按钮时候出现短暂粉红色点击效果，点击返回主菜单游戏回到主菜单界面，点击游戏关卡进入游戏界面)

　　

　　不同游戏主题显示不同数量的关卡，用到了游戏数据管理类，不同游戏主题显示的卡牌不同

LevelManager.cs (游戏管理脚本)

实现过程

选关游戏界面

　　新建画布，添加背景，设置标题，增加选关区域范围

　　选关区域使用纯白色作为背景(修改其透明度值)，调整选关区域位置

　　选关区域下方添加关卡信息(Panel默认是透明)

　　LevelManager下方创建游戏空物体对象(Content)，添加Panel，Panel上添加Grid Layout Group表格布局插件

　　Fixed Column Count 固定行

　　　　Constraint Count 每行固定最大值为5个单元表格

　　利用组格插件好处：更方便实现动态添加选项关卡

　　

LevelItemCell游戏单个关卡(点击关卡时的颜色)

　　动态生成关卡为未解锁状态

　　

　　

　　点击关卡时状态

　　

　　

　　关卡解锁状态

　　

　　添加Image覆盖LevelItemCell选关单元，调整透明度(改名lock,未解锁关卡时的颜色)

　　同点击鼠标让关卡变色一个原理

　　将LevelItemCell设置为预设体，使关卡能动态创建(业务与开发分离)

　　添加脚本LevelItemCell并挂到预设体LevelItemCell上(脚本与预设体同名看起来方便)

　　挂载完Apply更新，添加到源预设体上~

　　同理将LevelPanelCell也设置为预设体，动态创建一页关卡后会再动态创建关卡页

　　

　　添加脚本LevelManager,挂载到LevelManager控件上

　

　　　LevelManager用来管理所有关卡按钮

　　LevelManager脚本根据我们关卡数据定义，判断一共多少个关卡按钮。LevelManager来创建LevelPanelCell表格单元，LevelPanelCell表格单元是LevelItemCell

　　将Content关卡页面绑定到LevelManager关卡页面范围上

      public  RectTransform contenTrans;

　　计算panel的偏移

      readonly float PANEL_SPACE = 10f;   

      panelCellffset = contenTrans.rect.width + PANEL_SPACE;

　　计算出一共需要多少页

      int totalCount = ; //临时测试，一共18关
      readonly int ITEM_COUNT_PAGE = ;  //每一页显示15个关卡
      readonly float PANEL_SPACE = 10f;  

      pageCount = Mathf.CeilToInt((float)totalCount / ITEM_COUNT_PAGE);

　　Mathf.CeilToInt()上取整(Mathf.CeilToInt(1.5)、Mathf.CeilToInt(2.2)=3)

　　

　　获得游戏控件UI

public void Awake()
    {
        levelPanelCellPreb = Resources.Load<GameObject>("Prefabs/SelectLevel/LevelPanelCell");
        levelItemCellPreb = Resources.Load("Prefabs/SelectLevel/LevelItemCell") as GameObject;
        levelDescTxt = GameObject.Find("LevelDesc/text").GetComponent<Text>();
    }

　　创建表格panel，从0开始编号

void CreateLevelPanclCell(int pageInx)
    {
        GameObject panelObj = Instantiate(levelPanelCellPreb,contenTrans);
        RectTransform panelTrans = panelObj.GetComponent<RectTransform>();
        panelTrans.anchoredPosition = new Vector2(panelCellOffset * pageInx, );

        //确定本业 中具有的关卡元素个数
        int startId = ITEM_COUNT_PAGE * pageInx;
        //本业需要显示按钮的个数
        int count = totalCount - startId;

        if (count > ITEM_COUNT_PAGE)
        {
            count = ITEM_COUNT_PAGE;
        }

        //创建本页中所有关卡按钮
        for(int i =;i<count;i++)
        {
            //创建每一个关卡的按钮单元
            GameObject itemObj = Instantiate(levelItemCellPreb,panelTrans);

            LevelItemCell cell = itemObj.GetComponent<LevelItemCell>();

            cell.lvlMgr = this;

LevelManager.cs

　　因为我们默认初始化游戏18个关卡，一个选关界面存放15个关卡

　　所有关卡时出现出现两个选关界面

　　为了只出现一个选关界面

　　使用Unity提供的Mask插件

　　Mask插件：提供给需要Mask的图片修改渲染顶点，达到遮罩效果

　　在LevelManager控件上添加Mask插件

整体滑动效果

　　DOTween插件控制选关界面移动　　下载：传送门

　　下载完后，把解压的包，直接拖入工程 在unity 菜单栏 Tools—Demigiant—DOTween Utility Panel。点击后，在右图中点击Setup DOTween… 工具会导入必要的库。

滑动效果效果：

LevelItemCell.cs

　　num子节点下创建两个Image控件存放数字

　　定义Sprite[]数组，将图片绑定上去

public Sprite[] spr_nums;

　　用代码动态创建一个Image对象，并作为num的子节点

　　　　　　　GameObject obj = new GameObject("num1",typeof(Image));
            RectTransform rtf = obj.GetComponent<RectTransform>();
            rtf.SetParent(numTrans);

　　图片原始尺寸

            img.SetNativeSize();

　　图片的缩放比例

 rtf.localScale = new Vector3(,,);

　　当id<10时，定义图片放置的位置

 rtf.localPosition = Vector3.zero;

if (id < )
        {
            //完全用代码动态创建一个Image对象，并作为num的子节点

            rtf2.localScale = new Vector3(, , );
            rtf2.localPosition = new Vector3(scale * rtf2.rect.width /  + , , );

　　同理个位数，不同在于图片摆放的位置

数据管理类

    我们需要有一个类，能够使各处都能够便利访问。并且这个类对象实例，只需要一个

Unity_单例模式

　　第一个游戏主题只有18关

　　第一个游戏主题有20关

　　(　Unity引擎加载场景有点慢(´･_･`) 　)

　　点击不同主题按钮选择不同主题的关卡

    void OnClickThemeBtn(THEME_ID theme)
    {
        SceneManager.LoadScene("SelectLevel");
        DataMgr.Instance().themeId = theme;
