Unity3D笔记 GUI 二 、实现选项卡一窗口

实现目标：
　　1、个性化Box控件
　　2、新建TextAmount样式
　　3、新建TextItem样式

一、个性化Windows界面

设置GUI Skin

1.2 部分代码

Rect stateBox = new Rect(, , , );
Rect weaponBox = new Rect(, , , );

GUI.Box(stateBox, "");
GUI.Box(weaponBox, "");//['wepən] n. 武器,兵器

1.3效果

二、新建TextAmount样式

　　2.1、 代码

    #region 个性化Box控件
    Rect stateBox = new Rect(, , , );
    Rect weaponBox = new Rect(, , , );
    public Texture box1;
    public Texture box2;
    public Texture box3;
    Rect box1Rect = new Rect(, , , );
    Rect box2Rect = new Rect(, , , );
    Rect box3Rect = new Rect(, , , );
    #endregion

        #region 实现Status窗口
        GUI.Box(stateBox, "");
        GUI.Box(weaponBox, "");//['wepən] n. 武器,兵器
        GUI.DrawTexture(box1Rect, box1);
        GUI.DrawTexture(box2Rect, box2);
        GUI.DrawTexture(box3Rect, box3);
        #endregion

2.4、TextAmount

三、新建TextItem样式

3.1、个性化数字的现实
