Build a Classic Plane Shooter Game with Python and Pygame – Step‑by‑Step Guide

Remember the classic WeChat "Plane Battle" game? This article walks through recreating a similar airplane shooter using Python and Pygame.

Environment Setup

The game code is based on a simple Pygame project (version 1.0) and requires Python 3, PyCharm, the pygame module, and some built‑in modules.

pip install -i https://pypi.douban.com/simple/ pygame

Player Plane

def main():
    global is_hit
    global nums
    screen = pygame.display.set_mode((480, 852), 0, 32)
    background = pygame.image.load("./feiji/background.png")
    # 创建飞机
    hero = HeroPlane(screen)
    enermy_plane = EnermyPlane(screen)
    while True:
        global hero_nums
        global enermy_nums
        # 显示背景
        screen.blit(background, (0, 0))
        # 显示我方飞机
        hero.display()
        # 测试是否被子弹击中
        hero.test(enermy_plane.bullets)
        if hero.is_hit:
            hero_nums += 1
        if hero_nums == 10:
            hero.image = pygame.image.load("./feiji/hero_blowup_n1.png")
        elif hero_nums == 20:
            hero.image = pygame.image.load("./feiji/hero_blowup_n2.png")
        elif hero_nums == 30:
            hero.image = pygame.image.load("./feiji/hero_blowup_n3.png")
        elif hero_nums == 40:
            hero.image = pygame.image.load("./feiji/hero_blowup_n4.png")
        elif hero_nums > 50:
            break

Enemy Plane

# 显示敌飞机
enermy_plane.display()
enermy_plane.test(hero.bullets)
if enermy_plane.is_hit:
    enermy_nums += 1
if enermy_nums == 10:
    enermy_plane.image = pygame.image.load("./feiji/enemy0_down1.png")
elif enermy_nums == 20:
    enermy_plane.image = pygame.image.load("./feiji/enemy0_down2.png")
elif enermy_nums == 30:
    enermy_plane.image = pygame.image.load("./feiji/enemy0_down3.png")
elif enermy_nums == 40:
    enermy_plane.image = pygame.image.load("./feiji/enemy0_down4.png")
elif enermy_nums > 50:
    enermy_plane = EnermyPlane(screen)
    enermy_nums = 0
else:
    enermy_plane.move()
    enermy_plane.fire()
# 控制飞机左右
key_control(hero)
# 刷新屏幕
pygame.display.update()
# 程序休眠0.01秒
time.sleep(0.01)

Keyboard Control

def key_control(hero):
    for event in pygame.event.get():
        if event.type == QUIT:
            print("exit")
            exit()
        elif event.type == KEYDOWN:
            if event.key == K_a or event.key == K_LEFT:
                hero.move_left()
                print("left")
            elif event.key == K_d or event.key == K_RIGHT:
                hero.move_right()
                print("right")
            elif event.key == K_SPACE:
                hero.fire()
                print("space")

Bullet Collision Detection

class BasePlane(object):
    def __init__(self, screen, x, y, image):
        self.x = x
        self.y = y
        self.screen = screen
        self.image = pygame.image.load(image)
        self.is_hit = False  # 此标志用来表示飞机是否被击中了
        self.bullets = []
    def test(self, bullets):
        for bullet in bullets:
            if self.x < bullet.x < self.x + self.image.get_width() and \
               self.y < bullet.y < self.y + self.image.get_height():
                self.is_hit = True
# 检测子弹碰撞
for item in self.bullets:
    for bullet in bullets:
        if item.x < bullet.x < item.x + item.image.get_width() and \
           item.y < bullet.y < item.y + item.image.get_height():
            item.is_hit = True
            bullet.is_hit = True

Summary

The simple version runs infinitely without power‑ups or larger aircraft; further enhancements will be added later.
