在Pygame中只按一次键

import pygame

pygame.init()

window_width = 800
window_height = 600
window = pygame.display.set_mode((window_width, window_height))
pygame.display.set_caption("My Game")

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE:
                # 处理空格键按下事件
                print("Space key pressed")

# 在游戏循环中更新游戏状态
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE:
                # 处理空格键按下事件
                print("Space key pressed")
                # 更新游戏状态
                player.jump()

    # 更新游戏状态
    player.update()

    # 绘制游戏界面
    window.fill((0, 0, 0))
    player.draw(window)
    pygame.display.flip()
