1、歼灭敌机
(1)增加敌机：设置敌机，随机从窗口顶部出现，往底部移动，随机从窗口顶部出现只需要设置初始纵坐标为顶部的一个固定值：
#敌机初始化
k = 0
enemy_x1 = 0
enemy_y1 = 0
(2)敌机移动
敌机随机出现
设定敌机速度
敌机随机出现，可以将初始位置设定在y = -24的位置(稍高于窗口顶部y = 0位置)
设定敌机速度，要确定速度就要设定时间t和路程s，时间设定为每执行一次程序t0，时间参数k，设定每执行一次程序移动的像素为5，根据实际效果调整参数，飞机从上到下运行总时间为(1000 + 90)/10 = 109*t0，总路程s = (109*t0)*5:
#随机出现敌人
#敌人1
if k == 0:
enemy_x1 = random.randint(-24, 426)
enemy_y1 = -24
elif k == 90:
k = -1000
k += 10
enemy_y1 += 5
同理，可以再增加一个敌机，但是飞机初始出现的位置需要和前一个区别：
#敌人2
if l == 80:
enemy_x2 = random.randint(-24, 426)
enemy_y2 = -24
elif l == 170:
l = -1170
l += 10
enemy_y2 += 5
2、碰撞检测
只要检测到子弹“左边缘”横坐标在敌机“左边缘”和“右边缘”之间且子弹“顶部”纵坐标在敌机“底部坐标之上”，或者子弹“右边缘”横坐标在敌机“左边缘”和“右边缘”之间且子弹“顶部”纵坐标在敌机“底部坐标之上”，则判定子弹会和敌机发生碰撞：(由于设定的子弹速度很快，暂时没有判断子弹“顶部”纵坐标在敌机“底部坐标之上”)
#检测碰撞
def collide(button_x1, enemy_x1, enemy_y1, score_count): # x1子弹中心横坐标，X2敌机中心横坐标
collide_x1 = enemy_x1
collide_y1 = enemy_y1
if ((enemy_x1 - 15) <= (button_x1 - 4) <= (enemy_x1 + 15)) or ((enemy_x1 - 15) <= (button_x1 + 4) <= (enemy_x1 + 15)):
collide_x1 = random.randint(-24, 426)
collide_y1 = -65
score_count +=1
print(score_count)
return collide_x1, collide_y1, score_count
3、增加声音
初始化及加载：
#音乐初始化及加载
pygame.mixer.init()
pygame.mixer_music.load('button.wav')
显示子弹声音：
#显示子弹声音
pygame.mixer_music.play()
4、计算分数
计算分数比较简单，这里只选择了三位数，即最大为999，但是提前需要准备好1-9的数字图片:
#计算并显示分数
units = score_count//1%10
tens = score_count//10%10
hundreds = score_count//100%10
units_picture = score_picture_list[units]
tens_picture = score_picture_list[tens]
hundreds_picture = score_picture_list[hundreds]

PS：可以看出，这样的写法代码量很大，下一步会基于“面向对象”和“程序提炼”来优化一遍上述的程序。
