我正在关注一个教程,我试图让我的文本出现在屏幕上,这是我的代码,但文本不会出现:
from __future__ import division
import math
import sys
import pygame
class MyGame(object):
def __init__(self):
pygame.mixer.init()
pygame.mixer.pre_init(44100, -16, 2, 2048)
pygame.init()
self.width = 800
self.height = 600
self.screen = pygame.display.set_mode((self.width, self.height))
self.bg_color = 0, 0, 0
font = pygame.font.Font(None, 100)
text = font.render("text that should appear", True, 238, 58, 140)
self.FPS = 30
self.REFRESH = pygame.USEREVENT+1
pygame.time.set_timer(self.REFRESH, 1000//self.FPS)
def run(self):
running = True
while running:
event = pygame.event.wait()
if event.type == pygame.QUIT:
running = False
elif event.type == self.REFRESH:
self.draw()
else:
pass
def draw(self):
self.screen.fill(self.bg_color)
screen.blit(text, [400,300])
pygame.display.flip()
MyGame().run()
pygame.quit()
sys.exit()
知道为什么会这样吗?我忘记导入库还是我的绘图方法有问题?
