项目描述：为落实抗击疫情的精神设计了一款类似于愤怒的小鸟模型的一款小游戏，基于pygame开发。
一、背景介绍：
- 疯狂的小鸟作为被大众熟知的一款游戏，在当年许多单机游戏中也是脱颖而出。又正值如今疫情严峻，为了缓解大家一个多月的疫情封寝带来的焦虑以及感受防疫工作者面对新冠病毒的勇敢果决，我们在这一款游戏之上做了一些改编和拓展，做出了一款关于防疫医生与新冠病毒的游戏。游戏的主要流程是通过控制医生实现对病毒的精确打击，要求便是将病毒全部消灭。如果成功消灭会显示相应分数，作为向医生的鼓励以及增加我们防疫的信心

另外，游戏的开始游戏界面、游戏的失败界面、游戏暂停界面、游戏关卡切换界面与这里游戏界面中的部分也大同小异，主要包括相关按钮，标题的载入以及对事件（主要是按钮触发）的检测
2.设计关卡
for i in range(3):
doctors.append(
Doctor(screen=self.screen, imagepaths=self.cfg.IMAGEPATHS['doctor'],
loc_info=(45 * i, self.screen_size[1] - 40, 20))
)
if self.level_pointer == 1:
covids.append(
COVID(screen=self.screen, imagepaths=self.cfg.IMAGEPATHS['covid'],
loc_info=(1100, self.screen_size[1] - 60, 25))
)
covids.append(
COVID(screen=self.screen, imagepaths=self.cfg.IMAGEPATHS['covid'],
loc_info=(1200, self.screen_size[1] - 60, 25))
)
walls.append(
Slab(screen=self.screen, imagepaths=self.cfg.IMAGEPATHS['wall'], x=700, y=250, width=30,
height=self.screen_size[1] - 250)
)
主要通过添加相关元素（包括医生，病毒，障碍[通过木块体现]，墙），设置其位置来体现关卡特点，其余关卡也是大同小异
3.碰撞检测（核心）
通过检测物体之间（主要是医生与病毒，医生与障碍，医生与墙，病毒与病毒，病毒与墙，病毒与障碍）图像是否发生重叠来体现是否发生碰撞，若发生碰撞则修改碰撞物体的速度大小与方向，这里体现了病毒医生之间的碰撞，其余碰撞的产生也能通过类似功能实现
def collision(self, sprite1, sprite2):
is_collision = False
elasticity, block_elasticity = 0.8, 0.7
if sprite1.type in ['covid', 'doctor'] and sprite2.type in ['covid', 'doctor']: #病毒医生之间的碰撞
dx, dy = sprite1.loc_info[0] - sprite2.loc_info[0], sprite1.loc_info[1] - sprite2.loc_info[1]
dist = math.hypot(dx, dy)
if dist < sprite1.loc_info[2] + sprite2.loc_info[2]:
tangent = math.atan2(dy, dx)
angle = 0.5 * math.pi + tangent
angle1, angle2 = 2 * tangent - sprite1.velocity.angle, 2 * tangent - sprite2.velocity.angle
magnitude1, magnitude2 = sprite2.velocity.magnitude, sprite1.velocity.magnitude
sprite1.velocity, sprite2.velocity = VelocityVector(magnitude1, angle1), VelocityVector(magnitude2,
angle2)
sprite1.velocity.magnitude *= elasticity
sprite2.velocity.magnitude *= elasticity
overlap = 0.5 * (sprite1.loc_info[2] + sprite2.loc_info[2] - dist + 1)
sprite1.loc_info[0] += math.sin(angle) * overlap
sprite1.loc_info[1] -= math.cos(angle) * overlap
sprite2.loc_info[0] -= math.sin(angle) * overlap
sprite2.loc_info[1] += math.cos(angle) * overlap
is_collision = True
