经过测试其中角色进入游戏需要发送的最少数据包及顺序如下：

• S_OPCODE_HOUSEMAP
• S_OPCODE_LOGINTOGAME
• 4个空字节
• S_OPCODE_OWNCHARSTATUS
• S_OPCODE_MAPID
• S_OPCODE_CHARPACK
• S_OPCODE_CHARTITLE
• S_OPCODE_OWNCHARSTATUS

接下来分析对应处理代码，将可以延后实现的代码注释，列举核心功能点

C_OPCODE_LOGINTOSERVER

需要实现：

• 世界系统(所有游戏对象的存储和删除)：World.py
• 复活点系统(重新登入或者使用回家卷轴返回的位置)：GetBackRestartTable.py、GetBackRestart.py、GetBackTable.py
• 村庄位置系统(返回每个村庄的回城点)：TownLocation.py

S_OPCODE_HOUSEMAP

需要实现：S_InitialAbilityGrowth.py

S_OPCODE_LOGINTOGAME

需要实现：S_LoginToGame.py

S_OPCODE_OWNCHARSTATUS

需要实现：

• 游戏时钟系统(游戏时间和现实时间的相互映射):GameTime.py、GameTimeClock.py
• 玩家仓库系统(玩家仓库道具的添加、更新和删除，以及道具重量和数目的统计；初期可以跳过道具的相关操作的具体实现，只需返回空即可)：Inventory.py、PcInventory.py

S_OPCODE_MAPID

需要实现：S_MapID.py

S_OPCODE_CHARPACK

需要实现：S_OwnCharPack.py

S_OPCODE_CHARTITLE

需要实现：S_CharTitle.py

延后实现：

• 道具系统
• 仓库系统
• 战争管理
• 视觉效果显示（中毒、水下）
• 祝福经验
• 血盟系统
• 结婚系统
• 地狱系统
• 在线奖励系统
• GM监视系统
• 角色封号系统
• 记忆坐标系统
• 服务器时间系统
• 灯光系统
• 技能系统
• 宠物系统
• 聊天系统
• 税收系统
• 装备道具系统

世界系统

World

实现游戏世界对象的存储，
获取游戏范围的可见对象

• 直线上的可见游戏对象：两个游戏对象间的可见对象（游戏地图可以看做一个大的二维数组矩阵，二维数组中任意两个元素相连，计算连线经过的所有二维元素，源码的createLineMap函数使用的是Bresenham画线算法）
• 矩形内的可见游戏对象：游戏玩家面向的前方矩形范围内的可见对象（源码的getVisibleBoxObjects主要用到了二维坐标系转换算法，以当前玩家位置为原点，朝向为X轴正方向建立坐标系，并将其他游戏对象的坐标都转换到此坐标系中）
• 圆内的可见游戏对象：游戏玩家周围范围内的可见对象（源码的getVisiblePlayer函数用的是近似算法，算的其实是圆的外切正方形内所有可见对象）

时钟系统

GameTime

实现现实世界时间到游戏时间的相互映射

角色仓库使用

前面角色登入后背包内是没有道具的，现在我们要实现仓库系统，角色登入后可打开背包查看道具，借用下角色登入时候的仓库封包

道具系统

仓库系统存储的是道具，所以在实现仓库系统前必须先实现道具系统

Item

道具模板对象抽象：

属性：

• 描述属性(材质、种类、强化等级、使用职业、道具本身的属性加层)

方法：

• 获取对应描述属性

Item.py、Weapon.py、EtcItem.py、Armor.py

ItemInstance

道具实例对象抽象：

属性：

• 个数
• 道具模板
• 重量
• 使用状态
• 强化状态（武卷强化、防卷强化、饰品强化）
• 道具强化后的属性加成（人物属性加成、人物抗性加成）

方法：

• 道具名称显示 => 火灵 +10 匕首（挥舞）
• 道具魔法加持效果(延后实现)

ItemInstance.py

ItemTable

道具系统管理对象抽象：

属性：

• 道具模板集合

方法:

• 从数据库加载道具模板到内存(材料道具、武器道具、防具道具)
• 使用道具模板创建道具实例

ItemTable.py

仓库系统

Inventory

仓库对象抽象：

属性：

• 仓库物品集合

方法：

• 计算仓库内物品的总数、重量
• 添加道具
