周六無聊,花了二個小時寫了一個游戲的大體框架.
Game.java

this.setLocation((this.getToolkit().getScreenSize().width - this.getWidth()) / 2,

this.setDefaultCloseOperation(3);
this.setResizable(false);
this.setVisible(true);
}
public void update(Graphics g)
{
if (this.imageBuffer != null)
{
this.getGraphics().drawImage(imageBuffer, 0, 0, this);
}
}
public void setImageBuffer(Image imageBuffer)
{
this.imageBuffer = imageBuffer;
}
}
還有三個類在下一篇.
