一个python MUD游戏, 设计参考自<MUD Game Programming>中的BetterMUD。
整个游戏世界由以下实体组成：
- Account
- Character(玩家或NPC)
- Item
- Room
- Portal
- Region
- Template(用于生成Character或Item)
游戏响应用户输入的字符形式的命令, 解析完交给玩家对应的Character中某个Command实例执行(通过调用Command.Execute).
游戏类Game提供一些基础事件, 比说某个角色尝试在某个房间发讲话 AttemptSay, 某个角色进入某个通道 AttemptEnterPortal。
单个事件根据需要调用各个涉及到的实体Entity.Query(conditon)查询事件能否发生, 再调用Entity.React(action)响应该事件, 做出反映, 从而完成一个事件. 具体请参考Game.Say/EnterPortal方法以及BasicLogic类的实现。
用户的单条命令的功能可以与游戏功能无关的, 也可以是由零个或多个游戏的基础事件组成, 甚至再直接点, 直接让零个或多个实体的响应某些动作.
以下是几个比较重要的方法/函数:
- Game.PorcessEvent
- Game.ExecuteCommand
- LogicEntity.React
- Command.Execute
第一层为游戏事件, 第二层为游戏事件实现时需要查询的实体条件或者调用到基础动作. Condition的命令已'Can'开头.
Event/Condition/Action都是像dict类型一样, 不过很想JavaScript中的Object可以通过Object.attrname引用Object[attrname].
Event/Condition/Action三者都包含一个特别的属性type指明其类型.
