You do not, however, get credit for destroying them during the end-stage bonus points. 头盔helmet : The helmet power up grants you a temporary force field that makes you invulnerable to enemy shots, just like the one you begin every stage with. 铲子shovel : The shovel power up turns the walls around your fortress from brick to stone. This makes it impossible for the enemy to penetrate the wall and destroy your fortress, ending the game prematurely. The effect, however, is only temporary, and will wear off eventually. 星星star : The star power up grants your tank with new offensive power each time you pick one up, up to three times. The first star allows you to fire your bullets as fast as the power tanks can. The second star allows you to fire up to two bullets on the screen at one time. And the third star allows your bullets to destroy the otherwise unbreakable steel walls. You carry this power with you to each new stage until you lose a life. 坦克tank : The tank power up grants you one extra life. The only other way to get an extra life is to score 20000 points. 定时器timer : The timer power up temporarily freezes time, allowing you to harmlessly approach every tank and destroy them until the time freeze wears off.手雷:拿起手雷的电源，立即清除屏幕上的任何敌人，包括装甲坦克，无论你击中他们多少次。但是，你不会因为在最后阶段摧毁它们而得到积分。头盔:头盔能量提升给你一个临时力场，使你对敌人的射击无坚不摧，就像你在每个阶段开始的时候一样。铲子:铲子的力量把堡垒周围的墙从砖变成石头。这使得敌人不可能穿透墙壁并摧毁你的堡垒，从而提前结束游戏。然而，这种影响只是暂时的，最终会逐渐消失。星型:每次你拿起一辆星型坦克，它就会给你的坦克提供新的进攻能力，最多三次。第一颗星可以让你发射子弹的速度与动力坦克一样快。第二颗星允许你在屏幕上同时发射两颗子弹。第三颗星可以让你的子弹摧毁原本坚不可摧的钢铁墙。你带着这种力量进入每一个新的阶段，直到你失去一条生命。坦克:坦克的能量增加可以让你多活一次。获得额外生命的唯一方法是获得20000分。定时器:定时器暂时冻结时间，允许你无害地接近每一辆坦克并摧毁它们，直到冻结时间消失。 """ # bonus types 道具类型 (BONUS_GRENADE, BONUS_HELMET, BONUS_SHOVEL, BONUS_STAR, BONUS_TANK, BONUS_TIMER) = range(6) def __init__(self, level): global sprites # to know where to place 在哪个地图(关卡) self.level = level # bonus lives only for a limited period of time 奖励只在有限的一段时间内有效 self.active = True # blinking state 闪烁状态 self.visible = True # 道具随机出现的地点 self.rect = pygame.Rect(random.randint(0, 416 -
