课程设计要做一个游戏,由于对C++不是很熟悉,老师也准许使用java 或者其他的语言,在.net我学过事件,一种委托回调,但是在java 我不是很了解,应该原理都相同吧!
游戏大致是这样的,现在这在写成功判断!于是我自己加了一个事件\
package com.zhaojun.base;
import org.w3c.dom.events.Event;
import java.util.*;
/**

public class Game {
/* 地图枚举 */
public enum MAP_USER {
Red, Black, Null,
}
/* 记录错误日志 */

/* 记录日志 */
private StringBuilder arrivedBuilderLog;
/* 游戏地图 */
private MAP_USER[][] map;
public int getCount() {
return this._count;
}
public int getAllCount() {
return this._all_count;
}
private int _xcount;
private int _ycount;
/* 记录胜利人 */
private MAP_USER winUser = MAP_USER.Null;
private Dictionary<MAP_USER, String> _userMsg;
private int _count;// 走了多少
private int _all_count;// 一共可以走多少
private Collection winlistener;

//下棋失败
if (!game.inputGo(var11, var12, user)) {
System.err.println(game.getError());
continue;
} else {
game.showMap();
if (userint == 1) {

}
}
1.首先要使用事件,自己就必须写一个接口 继承EventListener 然后里面写一个需要实现的接口方法
/**
* 成功接口
*/
public interface WinEvent extends EventListener {
public void DoEvent();
}
private Collection winlistener;
/**
* 添加成功事件
*
* @param listener
*/
public void addWinListener(WinEvent listener) {
if (winlistener == null) {
winlistener = new HashSet();
}
this.winlistener.add(listener);
}
private void notifyDoEvent() {
Iterator iter = winlistener.iterator();
while (iter.hasNext()) {
WinEvent listener = (WinEvent) iter.next();
listener.DoEvent();
}
}
2.实现基本的添加事件和通知就可以了;;;接下来就是使用了
哈哈,成功了!
