碰撞消除实现关键是遍历玩家坦克和敌军子弹和敌军坦克列表的坐标相交判定 以及 敌军坦克和玩家子弹列表的坐标相较判定
鉴于子弹和坦克都是正方形的图片，使用圆的相交判定来确定是否相交

碰撞消除在各个类的dead方法中实现
for e in enemys:
for my_bullet in mytank.MyTank.bullets:
if math.sqrt((e.pos_x+enemy_wid/2-my_bullet.pos_x-bullet_wid/2)**2+(e.pos_y+enemy_hig/2-my_bullet.pos_y-bullet_hig/2)**2) < (enemy_wid/2+bullet_wid/2):
enemys.remove(e)
mytank.MyTank.bullets.remove(my_bullet)
放在main.py中 pygame.time.delay(10)前即可完成敌军和我方子弹的碰撞消除，自己和敌方子弹的碰撞消除同理即可，想了一下还是给个运行图吧（随机类型敌军坦克，并且少于6个，自动生成到6个）
