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()
