2.2 BinaryDataMgr

保存数据，读取数据

读取Excel表生成的二进制文件，加载到内容中以供使用

3、使用步骤

3.1 根据规则创建Excel配置表

创建的Excel表需要放置到ArtRes/Excel路径下

Excel配置规则

•     第一行：字段名
•     第二行：字段类型（字段类型一定不要配置错误，字段类型目前只支持int float bool string）如果想要在添加类型，需要ExcelTool的GenerateExcelBianary和BianryDataMgr的LoadTable方法当中对应添加读写的逻辑
•     第三行：主键是哪一个字段 需要通过key来标识主键
•     第四行：描述信息（只是给别人看，不会有别的作用）
•     第五行~第n行：就是具体数据信息
•     下方的表名决定类数据结构类，容器类，2进制文件的文件名

3.2 点击按钮GenerateExcelInfo

生成所有Excel表的数据结构类、数据结构容器类和二进制数据文件

 

3.3 完善BinaryDataMgr的InitData()方法，将自己创建的表进行加载

    public void InitData(){//加载自己的表到内存//LoadTable<TowerInfoContainer, TowerInfo>();//LoadTable<PlayerInfo1Container, PlayerInfo1>();//LoadTable<TestInfoContainer, TestInfo>();LoadTable<WeaponItemContainer, WeaponItem>();}

3.4 初始化数据，加载数据到内存

BinaryDataMgr.Instance.InitData()        加载二进制数据到内存当中

BinaryDataMgr.Instance.GetTable<TowerInfoContainer>()        获取需要使用的表的数据

        BinaryDataMgr.Instance.InitData();WeaponItemContainer data = BinaryDataMgr.Instance.GetTable<WeaponItemContainer>();foreach (var item in data.dataDic.Values){Debug.Log($"id:{item.id}-name:{item.name}-des:{item.des}-money:{item.money}-ATK:{item.atk}");}
