import java.awt.geom.*;

class RollingBall extends JPanel {

Ellipse2D.Float ball = new Ellipse2D.Float( -100, 100, 50, 50 );

public void paintComponent( Graphics g ) {

super.paintComponent( g );

Graphics2D g2 = ( Graphics2D ) g;

// Draw the ball

g2.fill( ball );

// Draw the rotating ellipse by skewing the Device Space

double angdeg = // One rotation per ball's travelling over its perimeter

ball.x++ % ( Math.PI * ball.width ) / ( Math.PI * ball.width ) * 360;

g2.rotate( Math.toRadians( angdeg ), ball.getCenterX( ), ball.getCenterY( ) );

g2.scale( .5, 1 );

g2.translate( ball.getCenterX( ), 0 );

g2.setColor( Color.gray );

g2.fill( ball );

}

public void roll( ) throws Exception {

while( true ) {

repaint( );

Thread.sleep( 8 );

}

public static void main( String[ ] args ) throws Exception {

RollingBall rb = new RollingBall( );

Q3: C程编程打砖块游戏编代码如何使小球碰撞后改变方向(通过圆心坐标距离等建立函数....) 万分感谢

给一个建议参考，如果你觉得有用可以试试哈~

用一个结构体定义小球，包含的其中一个变量：short direction；用来指示运动方向，再包含一个函数指针，指向一个函数如：short funL（）；若小球四周均没有障碍，返回0，优先判断上下，再判断左右，或反过来，再根据哪个方向有障碍返回1~4，1~4分别代表什么方向自己定义，可以用宏，若函数返回1~4，根据相应的情况改变变量direction的值就可以了

Q4: 这个C语言打砖块的代码，砖块如何实现刷新(砖块怎么消失)

c语言游戏中实现动画靠的是1秒钟多于25次的刷新。大一用easyx做过类似的，现在有点忘了，核心思想大概是

while(判断游戏未结束)//时间没停，未触发游戏终止标志

{

for(int i=0;iobjectNum;i++)

{

//根据时间更新每个砖块的状态

//如果某砖块的flag设为被打到，清除该物品，如果是链表删节点

//未被打到，砖块.y更新

}

//画背景图

for(int i=0;iobjectNum;i++)
