Java编程实现游戏中的简单碰撞检测功能示例

private boolean hittank(Tank t){
     Point Tank=new Point ((t.getX()+40),(t.getY()+40));
     Point Shell=new Point(((this.x)+10),((this.y)+10));
     int Tankr=40;     //Tank的半径
     int Shellr=10;    //Shell的半径
     double safedistance =Tankr+Shellr;  //安全距离
     double realdistance = Math.sqrt(Math.pow((Tank.x-Shell.x), 2)+(Math.pow((Tank.y-Shell.y), 2))); //实际距离
     boolean ishit=false;   //判断标志变量
     if(realdistance<safedistance)
     {
       ishit=true;
     }
     return (ishit);
}
