示例中用到的枚舉
 /**buff藥水道具枚舉*/
    public enum enumYaoshui
    {
        addHp = 1,      //加血藥水、
        maxHp,          //增加血量上限藥水永久
        addLuck         //爆率藥水有時效
    }
    /**消耗類物品枚舉*/
    public enum enumFood
    {
        money = 1,    ///消耗類物品 錢 食物 心情 燃料
        food,
        fuel,
        happy,
        wood,
        stone,
        magic
    }
    /**寶箱枚舉*/
    public enum enumChack
    {
        Chack0 = 1,    //寶箱
        Chack1,
        Chack2
    }
    /**炮臺枚舉*/
    public enum enumPaotai
    {
        Paotai0 = 1,  
        Paotai1,
        Paotai2,
        Paotai3
    }
