[英]Pygame window displays blank black screen
Here is my code, please keep in mind that I picked up python a couple of days ago so my code may be incorrectly made, ect. 这是我的代码,请记住,几天前我选择了python,因此我的代码可能制作不正确,等等。 I am trying to make a window that will display some text (beta) and will display two small rectangles that I want to make into buttons.
我正在尝试制作一个窗口,该窗口将显示一些文本(测试版)并显示两个我想放入按钮的小矩形。
import sys
import pygame
from pygame.locals import *
pygame.init()
size = width, height = 720, 480
speed = [2, 2]
black = (0,0,0)
blue = (0,0,255)
green = (0,255,0)
red = (255,0,0)
screen = pygame.display.set_mode(size)
screen.fill((blue))
pygame.display.set_caption("BETA::00.0.1")
clock = pygame.time.Clock()
def game_intro():
intro = True
while intro:
for event in pygame.event.get():
print(event)
if event.type == pygame.QUIT:
pygame.quit()
quit()
gameDisplay.fill(blue)
largeText = pygame.font.Font('freesansbold.ttf',115)
TextSurf, TextRect = text_objects("BETA", largeText)
TextRect.center = ((display_width/2),(display_height/2))
gameDisplay.blit(TextSurf, TextRect)
pygame.draw.rect(gameDisplay, green,(150,450,100,50))
pygame.draw.rect(gameDisplay, red,(550,450,100,50))
pygame.display.flip(screen)
pygame.display.update(screen)
clock.tick(15)
Problems: 问题:
game_intro()
function is defined, but never called game_intro()
函数已定义,但从未调用 gameDisplay
instead of screen
4 times, also display_width, display_height
instead of width, height
gameDisplay
而不是screen
4次,还编写了display_width, display_height
而不是width, height
game_intro()
, code after your infinite loop is never called game_intro()
,永远不会调用无限循环之后的代码 pygame.display.update(screen)
does not work, it should be pygame.display.update()
to update the whole screen. pygame.display.update(screen)
不起作用,它应该是pygame.display.update()
以更新整个屏幕。 flip(screen)
also needs to be changed to flip()
flip(screen)
也需要更改为flip()
text_objects()
is not defined but I found the definition in the example you probably copied the code from :) text_objects()
但是我在示例中找到了定义,您可能从:)复制了代码 Corrected code: 更正的代码:
import sys
import pygame
from pygame.locals import *
pygame.init()
size = width, height = 720, 480
speed = [2, 2]
black = (0,0,0)
blue = (0,0,255)
green = (0,255,0)
red = (255,0,0)
screen = pygame.display.set_mode(size)
pygame.display.set_caption("BETA::00.0.1")
clock = pygame.time.Clock()
def text_objects(text, font):
textSurface = font.render(text, True, black)
return textSurface, textSurface.get_rect()
def game_intro():
screen.fill(blue)
largeText = pygame.font.Font('freesansbold.ttf',115)
TextSurf, TextRect = text_objects("BETA", largeText)
TextRect.center = ((width/2),(height/2))
screen.blit(TextSurf, TextRect)
pygame.draw.rect(screen, green,(150,450,100,50))
pygame.draw.rect(screen, red,(550,450,100,50))
pygame.display.flip()
pygame.display.update()
clock.tick(15)
intro = True
while intro:
for event in pygame.event.get():
print(event)
if event.type == pygame.QUIT:
pygame.quit()
quit()
game_intro()
