如何在pygame中以正确的方式使用blit（）？
我试图制作一个纹理游戏，但是它没有错误。我将显示代码。
import time
import pygame
from pygame.locals import \*
def Main():
pygame.mixer.init()
pygame.mixer.music.load(r"C:\...\OMFG+-+Ice+Cream.mp3")
pygame.mixer.music.play(-1)
pygame.init()
screen = pygame.display.set_mode((640, 480))
screen.fill((0,0,0))
pygame.display.set_caption("3 Minutes Left!!!")
font = pygame.font.Font('freesansbold.ttf', 18)
intro_1 = font.render('3', True, (255,255,255))
intro_2 = font.render('Minutes', True, (255,255,255))
intro_3 = font.render('Left!!!', True, (255,255,255))
time.sleep(1)
screen.blit(intro_1, (140, 30)) #This isn't working.
time.sleep(1)
screen.blit(intro_2, (340, 30)) #This isn't working.
time.sleep(1)
screen.blit(intro_3, (540, 30)) #This isn't working.
Main()
我认为代码screen.blit将与while循环一起使用。所以我尝试了。
import time
import pygame
from pygame.locals import \*
def Main():
pygame.mixer.init()
pygame.mixer.music.load(r"C:\...\OMFG+-+Ice+Cream.mp3")
pygame.mixer.music.play(-1)
pygame.init()
screen = pygame.display.set_mode((640, 480))
screen.fill((0,0,0))
pygame.display.set_caption("3 Minutes Left!!!")
font = pygame.font.Font('freesansbold.ttf', 18)
intro_1 = font.render('3', True, (255,255,255))
intro_2 = font.render('Minutes', True, (255,255,255))
intro_3 = font.render('Left!!!', True, (255,255,255))
while True: #This isn't working.
time.sleep(1)
screen.blit(intro_1, (140, 30)) #This isn't working.
time.sleep(1)
screen.blit(intro_2, (340, 30)) #This isn't working.
time.sleep(1)
screen.blit(intro_3, (540, 30)) #This isn't working.
Main()
然后我启动了程序。但是pygame选项卡没有响应。所以我尝试了定义中的screen.blit。
import time
import pygame
from pygame.locals import \*
def Main():
pygame.mixer.init()
pygame.mixer.music.load(r"C:\...\OMFG+-+Ice+Cream.mp3")
pygame.mixer.music.play(-1)
pygame.init()
screen = pygame.display.set_mode((640, 480))
screen.fill((0,0,0))
pygame.display.set_caption("3 Minutes Left!!!")
font = pygame.font.Font('freesansbold.ttf', 18)
intro_1 = font.render('3', True, (255,255,255))
intro_2 = font.render('Minutes', True, (255,255,255))
intro_3 = font.render('Left!!!', True, (255,255,255))
while True: #This isn't working.
screen_blit(screen, intro_1, intro_2, intro_3) #This isn't working.
def screen_blit(screen, intro_1, intro_2, intro_3): #This isn't working.
time.sleep(1)
screen.blit(intro_1, (340, 30)) #This isn't working.
time.sleep(1)
screen.blit(intro_2, (340, 30)) #This isn't working.
time.sleep(1)
screen.blit(intro_3, (340, 30)) #This isn't working.
Main()
再次，没有回应。我怎样才能解决这个问题？？？

窗口没有响应，因为您不处理事件。您不会在窗口中看到任何内容，因为您没有更新显示内容。 最小的典型PyGame应用程序
-
needs a game loop
-
has to handle the events, by either ` pygame.event.pump() ` or ` pygame.event.get() ` .
-
has to update the display ` Surface ` , by either ` pygame.display.flip() ` or ` pygame.display.update() ` .
例如：
def Main(): # [...] while True: #This isn't working. # handle the events for event in pygame.event.get(): if event.type == pygame.QUIT: self.quit() # draw the scene screen.blit(intro_1, (340, 30)) # update the display pygame.display.flip()回答来源：stackoverflow
