python - Pygame 无响应显示

Question

因此，我正在尝试使用 Sprite 创建具有 X 和 Y 运动的基本 2D python 游戏的基础。

然而，尽管此处的代码尝试 screen.fill 和 screen.blit

，但显示没有响应

playerX = 50
playerY = 50
player = pygame.image.load("player.png")
width, height = 64*8, 64*8
screen=pygame.display.set_mode((width, height))
screen.fill((255,255,255))
screen.blit(player, (playerX, playerY))

我是不是漏掉了什么重要的东西？

一个最小的典型 PyGame 应用程序

• 有一个游戏循环

• 必须通过 pygame.event.pump() 处理事件或 pygame.event.get() .

• 必须更新 Surface whuch 分别代表显示窗口，由pygame.display.flip()或 pygame.display.update() .

参见 pygame.event.get() :

For each frame of your game, you will need to make some sort of call to the event queue. This ensures your program can internally interact with the rest of the operating system.

最小示例: repl.it/@Rabbid76/PyGame-MinimalApplicationLoop

import pygame

pygame.init()

playerX = 50
playerY = 50
player = pygame.image.load("player.png")
width, height = 64*8, 64*8
screen = pygame.display.set_mode((width, height))

# main application loop
run = True
while run:

    # event loop
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    # clear the display
    screen.fill((255,255,255))

    # draw the scene   
    screen.blit(player, (playerX, playerY))

    # update the display
    pygame.display.flip()
