& & & &在横版游戏中，实现屏幕随精灵移动而移动，要实现这个，首先要明白这个问题中的变与不变：
& & & && & & &不变：地图位置；
& & & && & & &变：精灵的位置、屏幕（或理解为所在图层）的位置；
& & & &故，说是滚动地图，其实是图层滚动；
& & & &从不变入手，首先要知道地图(CCTMXTileMap)的两个方法：
& & & && & & &1、map-&getMapSize()：地图的图块数
& & && & & &&&2、map-&getTileSize()：每一个图块的宽高
& & & &再而分析变：
& & & &精灵先移动，屏幕根据精灵移动的坐标去调整；
& & & && & & && & & &
& & & &总体分析前，先计算如下几个数值：
& & & && & & &地图宽度：tw=tilemap-&getMapSize().width*tilemap-&getTileSize().
& & & && & & &地图高度：th=tilemap-&getMapSize().height*tilemap-&getTileSize().
& & & && & & &屏幕宽度：ww=winsize.
& & && & & &&&屏幕高度：wh=winsize.
& & && & & &&&精灵坐标：x，y；
& & & &总体分析：首先准确判定精灵移动后的坐标，因为我们大部分游戏中的精灵都是一个图片，不是一个点，精灵的坐标到其图片的左右边和上下边是有距离的，分别为上图（此图出自时空猎人，其代码实现与本文无关）中的A边和B边，所以，整个精灵的水平坐标显示是有范围的（A&=x&=tw-A），而精灵的垂直坐标是同理的。这时，精灵坐标是能确定的，接下来是屏幕滚动了。屏幕滚动显然有以下三种情况：1、x&=ww/2；
2、ww/2&x&=tw-ww/2；3、tw-ww/2&x；在1情况，屏幕位置为（ww/2，wh/2）；在2中，屏幕位置为（x，wh/2）；在3中，屏幕位置为（tw-ww/2，wh/2）；有很多人可能已经发现，屏幕垂直坐标是不用去改变的，因为横版游戏在垂直上是没有滚动的（屏幕高度=地图高度，当然这里是指大部分）。最后，将屏幕中点（ww/2，wh/2）减去上面三种情况的屏幕位置点，得出滚动的距离，将距离值以坐标形式代入setPosition（）中。
完整代码如下：
void GameLayer::update(float dt)
this-&_hero-&updateDesiredPosition(dt);
//设置英雄位置
float posX=MIN(this-&_tilemp-&getMapSize().width*this-&_tilemp-&getTileSize().width-this-&_hero-&_centerToSides,MAX(this-&_hero-&_centerToSides,this-&_hero-&_desiredPosition.x));
float posY=MIN(3*this-&_tilemp-&getTileSize().height+this-&_hero-&_centerToBottom,MAX(_hero-&_centerToBottom,_hero-&_desiredPosition.y));
this-&_hero-&setPosition(ccp(posX,posY));
//地图滚动
CCSize winSize=CCDirector::sharedDirector()-&getWinSize();
int x=MAX(_hero-&getPositionX(),winSize.width/2);
int y=MAX(_hero-&getPositionY(),winSize.height/2);
x=MIN(x,(this-&_tilemp-&getMapSize().width*this-&_tilemp-&getTileSize().width)-winSize.width/2);
CCPoint actualPosition=ccp(x,y);
CCPoint centerOfView=ccp(winSize.width/2,winSize.height/2);
CCPoint viewPoint=ccpSub(centerOfView,actualPosition);
this-&setPosition(viewPoint);

我学习修改一个游戏客户端代码，发现鼠标不能移除游戏边框以外，仔细阅读代码。
发现好像是引擎的问题。（鼠标的协作模式已经修改，出现的问题是，在游戏里面移动鼠标，桌面的鼠标也会跟着移动）。请看代码这种是什么引擎？

锁定鼠标在某个窗口是调用SetCapture实现的，你找找有没有调用这个函数的地方呢
我一定是见鬼了！

这个是用direct写的。至于鼠标判定问题，我之前开发的小游戏中也遇到过，问题在于游戏设计本身 它的思路是一直获取鼠标位置，并且进行判定。
从代码可以得出。那么它对资源的消耗以及没有释放对鼠标的控制，这个在我之前开发的游戏中也遇到过。
那么可以转变下思路 可以在鼠标获取之前加入一些判定，比如单击游戏本身再进行获取，或者按ESC键能够退出等等一些优化
建议采用 ScreenToClient( )是把屏幕坐标转换为窗口坐标 ClientToScreen是把坐标从当前窗体转化成全屏幕的 或者判定完释放资源。
我手头没有源码不方便调试，只提供思路，具体还需要慢慢修改，祝好运。
新年做个贺岁小游戏

看 DirectX角色扮演游戏编程 或者 Windows游戏编程大师技巧 里，讲DirectInput的那一节。
