如何在python/pygame中覆盖瓷砖（图片）的区域？

Question

我想要做的是（0,390），（0,450），（610,390），（610,450） - 覆盖在名为（brick_tile）的平铺图像中。到目前为止，所有我必须是这样的：

import pygame 
from pygame.locals import* 

cloud_background = pygame.image.load('clouds.bmp') 
brick_tile = pygame.image.load('brick_tile.png') 

pink = (255, 64, 64) 
w = 640 
h = 480 
screen = pygame.display.set_mode((w, h)) 
running = 1 

while running: 
    screen.fill((pink)) 
    screen.blit(cloud_background,(0,0)) 
    screen.blit(brick_tile,(0,450)) 
    pygame.display.flip() 

    event = pygame.event.poll() 
    if event.type == pygame.QUIT: sys.exit()

用砖头瓦你就必须做块，块传输，块传输在一个循环：

import pygame 
import sys 
import itertools 

cloud_background = pygame.image.load('clouds.bmp') 
brick_tile = pygame.image.load('brick_tile.png') 

pink = (255, 64, 64) 
w = 640 
h = 480 
screen = pygame.display.set_mode((w, h)) 
running = 1 

def setup_background(): 
    screen.fill((pink)) 
    screen.blit(cloud_background,(0,0)) 
    brick_width, brick_height = brick_tile.get_width(), brick_tile.get_height() 
    for x,y in itertools.product(range(0,610+1,brick_width), 
           range(390,450+1,brick_height)): 
     # print(x,y) 
     screen.blit(brick_tile, (x, y)) 
    pygame.display.flip() 

while running: 
    setup_background()  
    event = pygame.event.poll() 
    if event.type == pygame.QUIT: sys.exit()
