python - 谁能告诉我如何使打印屏幕变蓝？

Question

这是原始问题:

如上所示，我需要打印蓝屏。这是我所做的:

import pygame

pygame.init()

blue = (0, 0, 255)

size = (width, height) = (640, 640)

screen = pygame.display.set_mode(size)

""" Game Drawing """
screen.fill(blue)
pyagme.draw.rect(screen, color, [x, y, 50, 50])
pygame.draw.rect(screen, blue, [mouseX, mouseY, 50, 50])
pygame.display.flip()

但是，只产生黑屏...谁能告诉我如何解决它？

Answer 1

好的，让我们修复代码中的错误。

import pygame

pygame.init()
blue = (0, 0, 255)
red = (255, 0, 0)
size = (640, 640)
screen = pygame.display.set_mode(size)

screen.fill(blue)
pygame.draw.rect(screen, red, [0,590, 50, 640])
pygame.display.update()

crashed = False
while not crashed:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            crashed = True
            pygame.quit()

现在您的屏幕为蓝色。而且您有一个红色正方形。
