Question

帝国时代是directDraw
directDraw创建了好几个surface来回翻转显示
后台画好后显示到前台、、、、
具体的、、、随便找一个游戏就可以找到类似代码啦！

Answer 1

有没有简单的方法，我对directDraw不了解，  也不是作游戏，只是达到他的效果就可以了。

Answer 2

我是想作个内存位图， 全屏显示，然后作个透明的矩形，在矩形内写字。不知这种方法可行否？　　　用不用加上屏蔽 热启动　键，和windows键的功能？？

Answer 3

先郑重声明：我是菜鸟
背景图片的加入：
//////////////////////////////////
先定义一个CBitmap 对象m_MyBitmap
从类构造函数里装载你要作为背景的图片m_MyBitmap.LoadBitmap(yourbmpID);
在OnEraseBkgnd(CDC* pDC) 中加入下列代码，
BITMAP bmp; 
m_MyBitmap.GetBitmap (&bmp); CRect rect; 
pDC->GetClipBox (&rect); CPoint org (0, 0); 
pDC->DPtoLP (&org); CDC dcMem; 
dcMem.CreateCompatibleDC (pDC); 
CBitmap *pOldBitmap = dcMem.SelectObject (&m_MyBitmap); dcMem.SetMapMode (pDC->GetMapMode ()); pDC->StretchBlt (rect.left, rect.top, rect.Width (), rect.Height (), 
&dcMem, org.x, org.y, bmp.bmWidth, bmp.bmHeight, SRCCOPY); pDC->SelectObject (pOldBitmap); 
/////////////////////////////////
另外滚动字幕的类我还没有测试，测试成功后再贴
