pygame精灵没有出现

问题描述

我正在尝试学习pygame，现在只是试图做一个非常简单的任务，加载精灵图像，但它没有出现。这是代码：

# -*- coding: utf-8 -*-
import pygame
#Defining Sprite class
class Character(pygame.sprite.Sprite):
    def __init__(self,location):
        # Call the parent class (Sprite) constructor
        super().__init__()
        self.image = pygame.transform.scale(pygame.image.load("mario-sprite.jpg"),(50,30))
        self.rect = self.image.get_rect()
        print(self.rect)
        self.rect.x = location[0]
        self.rect.y = location[1]
        
pygame.init()
# Set up the drawing window
screen = pygame.display.set_mode([1000,650])
print(screen)
screen.fill((250,250,250))
bg = pygame.image.load('bk_cloud.jpg')
bg = pygame.transform.scale(bg,(1000,650))
accesor = 'ABCDEFGHIJKLMnopQRSTUVWXYZ'
tiles = []
for c in accesor:
    temp = pygame.image.load('letter_'+c+'.png')
    tiles.append(pygame.transform.scale(temp,(100,50)))
print(bg)
all_sprites_list = pygame.sprite.Group()
player = Character([10,570])
#player.rect.x = 10
#player.rect.y = 570
#all_sprites_list.add(player)
screen.blit(player.image,player.rect)
screen.blit(bg,(0,0))
def update_floor(i):
    for j in range(10):
        screen.blit(tiles[j],((((i+j)%10)*100),600))
pos = 0
update_floor(0)
clock=pygame.time.Clock()
# Update the display
pygame.display.update()
# Run until the user asks to quit
running = True
while running:
    # Did the user click the window close button?
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    #update_floor(pos)
    #pos = pos + 1
    #all_sprites_list.draw(screen)
    pygame.display.update()
    clock.tick(2)
# Done! Time to quit.
pygame.quit()

我提到了一堆教程，但是我似乎很简单。有帮助吗？

解决方法

您已注释掉相关代码：all_sprites_list.add(player) 和 all_sprites_list.draw(screen)。取消注释相关代码：

all_sprites_list = pygame.sprite.Group()
player = Character([10,570])
player.rect.x = 10
player.rect.y = 570
all_sprites_list.add(player)  

def update_floor(i):
    for j in range(10):
        screen.blit(tiles[j],((((i+j)%10)*100),600))

pos = 0
clock=pygame.time.Clock()

# Run until the user asks to quit
running = True
while running:
    # Did the user click the window close button?
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    screen.blit(bg,(0,0))
    update_floor(pos)
    pos = pos + 1
    
    all_sprites_list.draw(screen)
    pygame.display.update()
    clock.tick(2)

# Done! Time to quit.
pygame.quit()
