1示例中用到的枚举
2 /**buff药水道具枚举*/
3    public enum enumYaoshui
4    {
5        addHp = 1,      //加血药水、
6        maxHp,          //增加血量上限药水永久
7        addLuck         //爆率药水有时效
8    }
9    /**消耗类物品枚举*/
10    public enum enumFood
11    {
12        money = 1,    ///消耗类物品 钱 食物 心情 燃料
13        food,
14        fuel,
15        happy,
16        wood,
17        stone,
18        magic
19    }
20    /**宝箱枚举*/
21    public enum enumChack
22    {
23        Chack0 = 1,    //宝箱
24        Chack1,
25        Chack2
26    }
27    /**炮台枚举*/
28    public enum enumPaotai
29    {
30        Paotai0 = 1,  
31        Paotai1,
32        Paotai2,
