Qt 4.6強大的QPropertyAnimation功能

我借用QPropertyAnimation寫了一個qgame_move的類(我會在對這個類增強),請看下面簡單的幾行就產生了2個不同的移動圖片,用qt來寫遊戲應該就更簡單了,這是Qt4.6的新功能(是從對岸博客看到的)

QPixmap birdimg=QPixmap(":/new/prefix1/Star.bmp").scaled(40,40);
QPoint p1(0, 360);//開始點
QPoint p2(310, 180);//結束點
QGame_move *a=new QGame_move(p1,p2,birdimg,ui->graphicsView);//動畫產生

QPoint p3(0, 0);
QPoint p4(310, 180);
QGame_move *a1=new QGame_move(p3,p4,birdimg,ui->graphicsView);
