示例中用到的枚举
 /**buff药水道具枚举*/
    public enum enumYaoshui
    {
        addHp = 1,      //加血药水、
        maxHp,          //增加血量上限药水永久
        addLuck         //爆率药水有时效
    }
    /**消耗类物品枚举*/
    public enum enumFood
    {
        money = 1,    ///消耗类物品 钱 食物 心情 燃料
        food,
        fuel,
        happy,
        wood,
        stone,
        magic
    }
    /**宝箱枚举*/
    public enum enumChack
    {
        Chack0 = 1,    //宝箱
        Chack1,
        Chack2
    }
    /**炮台枚举*/
    public enum enumPaotai
    {
        Paotai0 = 1,  
        Paotai1,
        Paotai2,
        Paotai3
