Python pygame通过类实例循环移动

如果跳转函数没有出现在第一个“while True”块中，我就不知道如何循环跳转函数。到目前为止，提议的替代方案都没有奏效。目前，我让它工作的唯一方法是在跳跃的每一步都按空格键

import pygame
from pygame import Color

HEIGHT = 500
WIDTH = 400
surface = pygame.display.set_mode((HEIGHT, WIDTH))


class Bird:
    def __init__(self):
        self.x = 10
        self.y = 300
        self.vy = 5
        self.jumpCount = 10
        self.isJump = False

    def draw(self):
        pygame.draw.rect(surface, Color("yellow"), (self.x, self.y, 10, 10))
        pygame.display.flip()

    def jump(self):

        if self.isJump:
            # using 'while' doesn't work either
            if self.jumpCount >= -10:
                # this doesn't work -> pygame.time.delay(100)
                print(self.jumpCount)
                self.y += (self.jumpCount * abs(self.jumpCount)) * -0.5
                self.jumpCount -= 1
            else:
                self.jumpCount = 10
                self.isJump = False

        return self.isJump

    def move(self):
        return

def run():
    bird = Bird()
    while True:

        pygame.time.delay(100)
        # only works if I put 'bird.isJump = True, bird.jump()' here, and then it loops continuously
        surface.fill(Color("blue"))
        bird.draw()
        for event in pygame.event.get():
            if event.type == pygame.KEYDOWN:
                if event.key == 32:
                    bird.isJump = True
                    bird.jump()
            if event.type == pygame.QUIT:
                pygame.quit()
        pygame.display.flip()


run()

您可以在每次运行游戏循环时调用

move

方法，以及

draw

，然后在单击空格时仅调用

jump

方法一次

结果将是（还有一些其他小的更改，例如调用

pygame.init

，使用

quit

而不是

pygame.quit

退出并删除多余的类成员）：

非常感谢，尽管我很好奇为什么我使用while语句或者在run中循环它都不起作用
