1. 从官网 python.org 下载 Python 并安装。

如果安装遇到问题，可来交流群讨论。

2. 用 pip 安装 pygame 模块

pip install pygame

3. 编写代码，在窗口里显示一张飞机图片

import pygame

pygame.init()
screen = pygame.display.set_mode((450,800), 0, 32)
plane = pygame.image.load('plane.png')
screen.blit(plane, (200, 400))

while True:
foreventin pygame.event.get():
ifevent.type == pygame.QUIT:
            pygame.quit()
            exit()
    pygame.display.update()

4. 让飞机随着鼠标位置进行移动

import pygame

pygame.init()
WHITE = (255, 255, 255)
screen = pygame.display.set_mode((450,800), 0, 32)
plane = pygame.image.load('plane.png')


while True:
foreventin pygame.event.get():
ifevent.type == pygame.QUIT:
            pygame.quit()
            exit()

    x, y = pygame.mouse.get_pos()
    x -= plane.get_width()/2
    y -= plane.get_height()/2
    screen.fill(WHITE)
    screen.blit(plane, (x, y))

    pygame.display.update()

5. 创建更多的敌机，从屏幕顶部向下移动

import pygame
import random

pygame.init()
WHITE = (255, 255, 255)
screen = pygame.display.set_mode((450,800), 0, 32)
plane = pygame.image.load('plane.png')

classEnemy:
defrestart(self):
self.x = random.randint(50, 400)
self.y = random.randint(-200, -50)
self.speed = random.random() * 2 + 0.5

def__init__(self):
self.restart()
self.image = pygame.image.load('enemy.png').convert_alpha()

defmove(self):
ifself.y < 800:
self.y += self.speed
else:
self.restart()

classPlane:
defrestart(self):
self.x = 200
self.y = 600

def__init__(self):
self.restart()
self.image = pygame.image.load('plane.png').convert_alpha()

defmove(self):
        x, y = pygame.mouse.get_pos()
        x-= self.image.get_width() / 2
        y-= self.image.get_height() / 2
self.x = x
self.y = y

plane = Plane()
enemies = []
for i in range(5):
    enemies.append(Enemy())

whileTrue:
for event in pygame.event.get():
if event.type == pygame.QUIT:
            pygame.quit()
            exit()

# 绘制背景
    screen.fill(WHITE)
# 绘制敌机
for e inenemies:
        e.move()
        screen.blit(e.image, (e.x,e.y))
# 绘制玩家
        plane.move()
        screen.blit(plane.image, (plane.x, plane.y))

    pygame.display.update()

6. 增加碰撞检测。如果撞上敌机，则游戏结束

# ……
# 前略

gameover = False
font = pygame.font.Font(None, 32)

while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
exit()

# 绘制背景
screen.fill(WHITE)

if not gameover:
# 绘制敌机
for e in enemies:
if checkCrash(e, plane):
gameover = True
e.move()
screen.blit(e.image, (e.x,e.y))
# 绘制玩家
plane.move()
screen.blit(plane.image, (plane.x, plane.y))
else:
text = font.render("Game Over!", 1, (0, 0, 0))
screen.blit(text, (165, 400))

pygame.display.update()

7. 发射子弹，消灭敌机

# ……

class Bullet:
def __init__(self):
self.x = 0
self.y = -1
self.image = pygame.image.load('bullet.png').convert_alpha()
self.active = False

def move(self):
if self.active:
self.y -= 5
if self.y < 0:
self.active = False

def restart(self):
mouseX, mouseY = pygame.mouse.get_pos()
self.x = mouseX - self.image.get_width() / 2
self.y = mouseY - self.image.get_height() / 2
self.active = True

# ……

def checkHit(enemy, bullet):
if (bullet.x > enemy.x and bullet.x < enemy.x + enemy.image.get_width()) and (
bullet.y > enemy.y and bullet.y < enemy.y + enemy.image.get_height()
    ):
enemy.restart()
bullet.active = False
#增加返回值
return True
return False

# ……

bullets = []
for i in range(10):
bullets.append(Bullet())
count_b = len(bullets)
index_b = 0
interval_b = 0

# ……

while True:
    # ……
if not gameover:
# 发射子弹
interval_b -= 1
if interval_b < 0:
bullets[index_b].restart()
interval_b = 30
index_b = (index_b + 1) % count_b
for b in bullets:
if b.active:
for e in enemies:
checkHit(e, b)
b.move()
screen.blit(b.image, (b.x, b.y))  
    # ……

8. 记录游戏分数

# ……
#分数
score = 0

while True:
    # ……
if not gameover:
# ……
# 绘制敌机
for e in enemies:
if checkCrash(e, plane):
gameover = True
e.move()
screen.blit(e.image, (e.x,e.y))
# 绘制玩家
plane.move()
screen.blit(plane.image, (plane.x, plane.y))
#在屏幕左上角显示分数
text = font.render("Socre: %d" % score, 1, (0, 0, 0))
screen.blit(text, (0, 0))
else:
text = font.render("Game Over!", 1, (0, 0, 0))
screen.blit(text, (165, 380))
#在屏幕中央显示分数
text = font.render("Socre: %d" % score, 1, (0, 0, 0))
screen.blit(text, (165, 420))

pygame.display.update()
