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()
