图像未使用 Pygame 打印到屏幕'Blit'

Question

我正试图用python制作一个类似Undertale的游戏，但我遇到了一个问题。当我试图把一个图像"闪电式"显示到屏幕上时，它不会显示。我正在"闪电"一颗心脏，我已经在第三方程序中将其重新调整到合适的大小。

import pygame  # Imports Pygame Library
import keyboard  # Imports Keyboard Library
# Defining Image Components
undertale_logo_ico = pygame.image.load('Undertale_Logo.ico')
Soul_Heart_Red = pygame.image.load('UndertaleHeart.png')

# Define Key-presses
def movement(key_pressed):
if key_pressed == 'right':
print('Right')
elif key_pressed == 'left':
print('Left')
elif key_pressed == 'up':
print('Up')
elif key_pressed == 'down':
print('Down')
else:
print('Not registered key')

# Execute Key Presses:
keyboard.on_press_key("right arrow", lambda _: movement('right'))
keyboard.on_press_key("left arrow", lambda _: movement('left'))
keyboard.on_press_key("up arrow", lambda _: movement('up'))
keyboard.on_press_key("down arrow", lambda _: movement('down'))
keyboard.on_press_key("d", lambda _: movement('right'))
keyboard.on_press_key("a", lambda _: movement('left'))
keyboard.on_press_key("w", lambda _: movement('up'))
keyboard.on_press_key("s", lambda _: movement('down'))
# Display Window Configuration
# area = screen.get_rect()
screen = pygame.display.set_mode((0, 0), pygame.FULLSCREEN)
background_colour = (0, 0, 0)
(width, height) = (300, 200)
pygame.display.set_caption('Game 1')
screen.fill(background_colour)
pygame.display.set_icon(undertale_logo_ico)
pygame.display.flip()
# Drawing Player
screen.blit(Soul_Heart_Red, [0, 0])
# Closing Script
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False

blit((位于代码的底部附近。

Answer 1

您必须在blit:之后更新显示

screen.blit(Soul_Heart_Red, [0, 0])
pygame.display.flip()                  # <---

Answer 2

您必须在blit之后更新显示。

screen.blit(Soul_Heart_Red, [0, 0])
pygame.display.update()
