用python写一个超级玛丽小游戏

为了用 Python 写一个超级玛丽小游戏，我们需要使用 pygame 库来创建游戏窗口并加载图片。以下是实现这个小游戏的一些步骤：

1. 导入 pygame 库并初始化

import pygame

pygame.init()

2. 设置游戏窗口大小和标题

screen = pygame.display.set_mode((640, 480))
pygame.display.set_caption("超级玛丽")

3. 加载背景图片和角色图片

background_image = pygame.image.load("background.png").convert()
player_image = pygame.image.load("player.png").convert_alpha()

4. 在游戏窗口中显示背景图片和角色图片

screen.blit(background_image, (0, 0))
screen.blit(player_image, (x, y))
pygame.display.update()

5. 处理用户输入事件

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

6. 让角色移动

keys = pygame.key.get_pressed()
if keys[pygame.K_LEFT]:
    x -= speed
if keys[pygame.K_RIGHT]:
    x += speed
if keys[pygame.K_UP]:
    y -= speed
if keys[pygame.K_DOWN]:
    y += speed

7. 添加碰撞检测

player_rect = player_image.get_rect()
player_rect.x = x
player_rect.y = y
if player_rect.colliderect(enemy_rect):
    print("Game Over")

完整代码如下所示：

import pygame
import sys

pygame.init()

screen = pygame.display.set_mode((640, 480))
pygame.display.set_caption("超级玛丽")

background_image = pygame.image.load("background.png").convert()
player_image = pygame.image.load("player.png").convert_alpha()

x = 0
y = 0
speed = 5

while True:
    screen.blit(background_image, (0, 0))
    screen.blit(player_image, (x, y))
    pygame.display.update()

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

    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        x -= speed
    if keys[pygame.K_RIGHT]:
        x += speed
    if keys[pygame.K_UP]:
        y -= speed
    if keys[pygame.K_DOWN]:
        y += speed

    player_rect = player_image.get_rect()
    player_rect.x = x
    player_rect.y = y
    enemy_rect = enemy_image.get_rect()
    enemy_rect.x = enemy_x
    enemy_rect.y = enemy_y
    if player_rect.colliderect(enemy_rect):
        print("Game Over")
