在java编写坦克大战游戏时，如何判断两辆坦克不能重叠运动，有什么简单的算法
对于这个小游里面的类的抽象很重要，对坦克及其它类我在这里面就不定义了，其实J2SE的API里面就有关于图形重叠的算法，就是这个intersects()方法，具体伪代码如下：

public boolean collidesWithTanks(java.util.ListTank tanks) {
for(int i=0; itanks.size(); i++) {
Tank t = tanks.get(i);
if(this != t) {
if(this.live t.isLive() this.getRect().intersects(t.getRect())) {
this.stay();
t.stay();
return true;
}
}
}
return false;
}
您可以根据自己的实际需求来改写，在我的百度文库里面有关于“坦克大战”的所有代码，如果有需要我可以把代码发给你，可以通过百度HI联系我。

JAVA坦克大战，这段代码为什么子弹的坐标在变，却不能repaint，但是按下任意键盘的建却重绘了呢？
Mypanel的 run方法里要调用repaint方法 否则你的repaint方法只会在keyPressed发生的时候才调用
修改一下两个地方
（1）
// 键盘获取事件的函数
public void keyPressed(KeyEvent arg0) {
// TODO Auto-generated method stub
if (arg0.getKeyCode() == KeyEvent.VK_J) {
if (hero.shot.size() 5) {
hero.shott();
}
}
if (arg0.getKeyCode() == KeyEvent.VK_W) {
hero.setSDC(hero.getSpeed(), 0, hero.getColor());
hero.moveUp();
} else if (arg0.getKeyCode() == KeyEvent.VK_S) {
hero.setSDC(hero.getSpeed(), 1, hero.getColor());
hero.moveDown();
} else if (arg0.getKeyCode() == KeyEvent.VK_A) {
hero.setSDC(hero.getSpeed(), 2, hero.getColor());
hero.moveLeft();
} else if (arg0.getKeyCode() == KeyEvent.VK_D) {
hero.setSDC(hero.getSpeed(), 3, hero.getColor());
hero.moveRight();
}
/**
* 这个repaint注释掉
*/
//this.repaint();
}
（2）
// 线程
/**
* 一秒钟60帧
*/
public void run() {
// TODO Auto-generated method stub
while(true){
this.repaint();
try {
Thread.sleep(1000 / 60);
} catch (InterruptedException e) {
// TODO 自动生成的 catch 块
e.printStackTrace();
}
}
}
