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()
