!important安全技术公司推出了世界上第一项P2V(行人对车辆)技术，该技术可以预测和防止车辆和弱势道路使用者之间的事故。这!important应用程序技术已经在手机间投入使用，该公司现在的目标是将这项创新技术集成到下一代自动驾驶汽车、卡车、公交车和商用多用途车的安全系统中，利用车辆的制动器进一步减少事故和死亡人数。全球首创的P2V技术为汽车安全技术增加了一个全新的维度，!important
这节我们研究下pygame的几种碰撞检测模式：如上图，左侧是默认的检测模式：基于矩形的检测(这也是性能最好的模式), 右侧是基于圆形的检测(性能略差于矩形检测)。矩形检测法虽然性能好，但是缺点也很明显：检测不准确，上图中"飞机与目标"从视觉上看，根本没碰到。 为了改进，pygame给这二种模式，新增了xxx_ratio的方法，允许指定检测时，指定二个目标的叠加程度，只有达到指定的叠加值，

1.介绍这节课我们将学习 pygame-Sprite。
Pygame的Sprite模块是一个用于处理精灵图像和动画的工具包。在游戏开发中，精灵通常指游戏中的角色或物体，在屏幕上移动或与其他精灵交互。 Sprite模块提供了一种简单而强大的方式来管理这些精灵。2.SpriteSprite模块基于面向对象的编程思想，将游戏中的角色和动画效果封装成一个个Sprite对象，从而实现更加灵活、可维护的

项目详细介绍在这个系列中，将制作一个雷霆战机游戏。碰撞发生了什么？Pygame中的默认碰撞类型是使用collide_rect()函数，该函数使用两个精灵的rect属性来计算它们是否重叠。这称为AABB碰撞，它非常快速和可靠。但是，如果精灵图像不是矩形，那么就会出现如图所示的情况。矩形重叠，那么collide_rect()就是True，但是玩家会感到沮丧，因为他们觉得自己应该已经成功地躲过流星（还差
