pip install pygame

第一步：导入项目所需模块

项目全部模块：

import math
import random

import pygame
from pygame import mixer

第二步：项目初始化

初始化项目：

WINDOW_WIDTH, WINDOW_HEIGHT = 800, 600
TANK_INIT_POS = (370, 480)
TANK_MOVE_DELTA = 5
PLANE_MOVE_DELTA = (4, 40)
PLANE_GOAL_POS_Y = 440
PLANE_OCCUR_RANGE_Y = (50, 150)
COLL_DIST_PLANE_BULLET = 27
BULLET_FIRE_RELA_TANK = (16, 10)

pygame.init()
screen = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption("坦克飞机大战")
icon = pygame.image.load('ico.png')
pygame.display.set_icon(icon)

background = pygame.image.load('background.png')

mixer.music.load("bg.wav")
mixer.music.play(-1)

tank_img = pygame.image.load('tank.png')
tank_pos_x, tank_pos_y = TANK_INIT_POS
tank_x_change = 0

plane_imgs = []
plane_x = []
plane_y = []
plane_x_change = []
plane_y_change = []
num_of_planes = 6

for i in range(num_of_planes):
    plane_img = pygame.image.load('plane.png')
    plane_imgs.append(plane_img)
    plane_x.append(random.randint(0, WINDOW_WIDTH - plane_img.get_rect().width))
    plane_y.append(random.randint(WINDOW_HEIGHT // 12, WINDOW_HEIGHT // 2))
    plane_x_change.append(PLANE_MOVE_DELTA[0])
    plane_y_change.append(PLANE_MOVE_DELTA[1])

bullet_img = pygame.image.load('bullet.png')
bullet_x = 0
bullet_y = tank_pos_y
bullet_y_change = 10
bullet_state = "ready"

score_value = 0
font = pygame.font.Font(None, 32)
text_x = 10
text_y = 10
over_font = pygame.font.Font(None, 64)

第三步：定义所需函数

def show_score(x, y):
    score = font.render(f"Score : {score_value}", True, (255, 255, 255))
    screen.blit(score, (x, y))


def game_over_text():
    over_text = over_font.render("GAME OVER", True, (255, 255, 255))
    screen.blit(over_text, (200, 250))


def draw_tank(x, y):
    screen.blit(tank_img, (x, y))


def draw_plane(x, y, i):
    screen.blit(plane_imgs[i], (x, y))


def fire_bullet(x, y):
    global bullet_state
    bullet_state = "fire"
    screen.blit(bullet_img, (x + BULLET_FIRE_RELA_TANK[0], y + BULLET_FIRE_RELA_TANK[1]))


def is_collision(enemy_x, enemy_y, bullet_x, bullet_y):
    distance = math.sqrt(math.pow(enemy_x - bullet_x, 2) +
                         (math.pow(enemy_y - bullet_y, 2))
                         )
    return distance < COLL_DIST_PLANE_BULLET

第四步：主逻辑

if __name__ == "__main__":
    running = True
    while running:
        screen.fill((0, 0, 0))
        screen.blit(background, (0, 0))
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                running = False

            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    tank_x_change = -TANK_MOVE_DELTA
                if event.key == pygame.K_RIGHT:
                    tank_x_change = TANK_MOVE_DELTA
                if event.key == pygame.K_SPACE:
                    if bullet_state == "ready":
                        mixer.Sound("laser.wav").play()
                        bullet_x = tank_pos_x
                        fire_bullet(bullet_x, bullet_y)

            if event.type == pygame.KEYUP:
                if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
                    tank_x_change = 0

        tank_pos_x += tank_x_change
        if tank_pos_x <= 0:
            tank_pos_x = 0
        elif tank_pos_x >= WINDOW_WIDTH - plane_img.get_rect().width:
            tank_pos_x = WINDOW_WIDTH - plane_img.get_rect().width

        for i in range(num_of_planes):
            if plane_y[i] > PLANE_GOAL_POS_Y:
                for j in range(num_of_planes):
                    plane_y[j] = 2000
                game_over_text()
                break

            plane_x[i] += plane_x_change[i]
            if plane_x[i] <= 0:
                plane_x_change[i] = PLANE_MOVE_DELTA[0]
                plane_y[i] += plane_y_change[i]
            elif plane_x[i] >= WINDOW_WIDTH - plane_img.get_rect().width:
                plane_x_change[i] = -PLANE_MOVE_DELTA[0]
                plane_y[i] += plane_y_change[i]

            collision = is_collision(plane_x[i], plane_y[i], bullet_x, bullet_y)
            if collision:
                explosion_sound = mixer.Sound("explosion.wav")
                explosion_sound.play()
                bullet_y = tank_pos_y
                bullet_state = "ready"
                score_value += 1
                plane_x[i] = random.randint(0, WINDOW_WIDTH - plane_img.get_rect().width)
                plane_y[i] = random.randint(PLANE_OCCUR_RANGE_Y[0], PLANE_OCCUR_RANGE_Y[1])

            draw_plane(plane_x[i], plane_y[i], i)

        if bullet_y <= 0:
            bullet_y = tank_pos_y
            bullet_state = "ready"

        if bullet_state == "fire":
            fire_bullet(bullet_x, bullet_y)
            bullet_y -= bullet_y_change

        draw_tank(tank_pos_x, tank_pos_y)
        show_score(text_x, text_y)
        pygame.display.update()
