pygame游戏之旅 游戏中添加显示文字

本文为大家分享了pygame游戏之旅的第5篇，供大家参考，具体内容如下

在游戏中添加显示文字：

这里自己定义一个crash函数接口：

def crash():
 message_diaplay('you crashed')

然后实现接口函数message_display(text)

def message_diaplay(text):
 largetext = pygame.font.font('freesansbold.ttf',115)
 textsurf, textrect = text_objects(text, largetext)
 textrect.center = ((display_width/2),(display_height/2))
 gamedisplay.blit(textsurf, textrect)
 pygame.display.update()
 time.sleep(2)
 game_loop()

在这其中定义了一个函数text_objects(text, largetext)，最后实现这个函数即可

def text_objects(text, font):
 textsurface = font.render(text, true, white)
 return textsurface, textsurface.get_rect()

全部代码：

import pygame
import time
 
pygame.init()
 
white = (255,255,255)
 
car_width = 100
 
display_width = 800
display_height = 600
 
 
gamedisplay = pygame.display.set_mode( (display_width,display_height) )
pygame.display.set_caption('a bit racey')
clock = pygame.time.clock()
 
carimg = pygame.image.load('car.png')
 
def car(x, y):
 gamedisplay.blit(carimg, (x,y))
 
 
def text_objects(text, font):
 textsurface = font.render(text, true, white)
 return textsurface, textsurface.get_rect()
 
def message_diaplay(text):
 largetext = pygame.font.font('freesansbold.ttf',115)
 textsurf, textrect = text_objects(text, largetext)
 textrect.center = ((display_width/2),(display_height/2))
 gamedisplay.blit(textsurf, textrect)
 pygame.display.update()
 time.sleep(2)
 game_loop()
 
def crash():
 message_diaplay('you crashed')
 
 
def game_loop():
 x = display_width * 0.45
 y = display_height * 0.8
 x_change = 0
 
 gameexit = false
 
 while not gameexit:
  for event in pygame.event.get():
   if event.type == pygame.quit:
    gameexit = true
   if event.type == pygame.keydown:
    if event.key == pygame.k_left:
     x_change = -5
    elif event.key == pygame.k_right:
     x_change = 5
   if event.type == pygame.keyup:
    if event.key == pygame.k_left or event.key == pygame.k_right:
     x_change = 0
   print(event)
  x += x_change
  gamedisplay.fill(white)
  car(x,y)
  if x > display_width - car_width or x < 0:
   gameexit = true
  pygame.display.update()
  clock.tick(60)
crash()
#game_loop()
pygame.quit()
quit()
