尝试比较我的精灵在pygame中的位置以结束游戏。

import pygame
import sys

# 初始化pygame
pygame.init()

# 设置窗口大小和标题
screen_width, screen_height = 800, 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("My Game")

# 创建精灵对象
class MySprite(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = pygame.Surface((50, 50))
        self.image.fill((255, 0, 0))
        self.rect = self.image.get_rect()
        self.rect.x = 100
        self.rect.y = 100

    def update(self):
        # 移动精灵
        self.rect.x += 1

# 创建精灵组
all_sprites = pygame.sprite.Group()
my_sprite = MySprite()
all_sprites.add(my_sprite)

# 游戏主循环
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # 更新精灵位置
    all_sprites.update()

    # 检查结束条件
    if my_sprite.rect.x >= screen_width:
        running = False

    # 绘制精灵和背景
    screen.fill((255, 255, 255))
    all_sprites.draw(screen)
    pygame.display.flip()

# 游戏结束
pygame.quit()
sys.exit()
