Question

我的角色不会正常跳跃，他不停地在地上摔跤。如果我按住键，我的角色不会停止走高。你对我如何解决它有什么想法吗？

pygame.draw.rect(screen, WHITE,(0,500, 1200, 50))

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



    hero.check_pos()
    monster1.walk()
    monster2.walk()
    hero.check_input()
    screen.fill(BLACK)
    hero.load_picture(screen)
    monster1.load_picture(screen)
    monster2.load_picture(screen)
    pygame.draw.rect(screen, WHITE,(0,500, 1200, 50))
    pygame.display.update() 


    clock.tick(40)

关于我上面的评论，将Hero类更改为以下内容：

JUMP_POWER = 10

class Hero():

    ...

    def check_input(self):
        key = pygame.key.get_pressed()

        ...

        elif key[pygame.K_UP]:
            if self.groundcontact:
                self.vy -= JUMP_SPEED

Pygame，继续跳跃和通过“地面”的故障
