这一节写客户端的具体实现方式。
为了演示,代码写的比较粗糙。
我们用一个EventCenter作为事件ID和事件的路由表,即根据某ID,即可定位到某处理事件的具体类,并根据参数处理这个事件。
前台应该有个类似这样的配置:
<group id = 0>
<event id =xx paramint1=xx paramint2=xx paramstr= xx>
....
</group >
<group id = 1>
</group>
我简单处理成了直接赋值,关于数据结构的定义,都较简单的使用了map,实际工作中,可根据情况做相应处理,这里仅说明一下大体原理
#include<map> using namespace std; struct Event { int eventid; string parastr; int paraint1; int paraint2; }; struct Group { enum { MAX_EVENT = 5}; int eventnum ; Event events[MAX_EVENT]; }; struct EventCenter; class Client { public: enum EventType { EVENT_NOTICE = 0, //弹提示 EVENT_CAMERA_MOVE =1 ,//移镜头 EVENT_TRANSPORT = 2 //传送 }; public: Client(void); ~Client(void); public: int loadfile(); int run(); public: void setgroupid(int id ){ groupid = id;}; void setcenter(EventCenter* c){ center = c;} private: typedef map<int,Group> Groups; typedef map<int,Group>::iterator Iterator; Groups config; int groupid; EventCenter* center; }; //事件类的父类,通过虚特性,EventCenter将调用子类的handle class EventHandle { public: virtual int handle(Event* event)=0; }; //将事件陆由到各个事件处理类 struct EventCenter { enum { MAX = 3}; public: void registerHandle(int id ,EventHandle* event){ eventhandles[id] = event; } void handleEvent(int id,Event* e ){ eventhandles[id]->handle(e);; } private: EventHandle* eventhandles[MAX];//为了演示方便,这个路由表简单表述成数组下标为键的结构 }; ///具体处理事件的类,可无限添加,只要在EventCenter中注册即可 //提示类 class NoticeEvent: public EventHandle { int handle(Event* event){ printf("新手指导员: %s\n",event->parastr.c_str()); return 0; } }; //移镜头 class MoveCameraEvent: public EventHandle { int handle(Event* event){ printf("镜头移动到x=%d y=%d\n",event->paraint1,event->paraint2); return 0; } }; //传送 class TransportEvent: public EventHandle { int handle(Event* event){ printf("将玩家传送至 场景 %d \n",event->paraint1); return 0; } };
