pygame游戏之旅 添加游戏介绍

本文为大家分享了pygame游戏之旅的第9篇，供大家参考，具体内容如下

在游戏开始之前定义一个函数，用来显示游戏介绍：

def game_intro():
 intro = True
 while intro:
   for event in pygame.event.get():
     print(event)
     if event.type == pygame.QUIT:
       pygame.quit()
       quit()
   gameDisplay.fill(white)
   largeText = pygame.font.Font('freesansbold.ttf',115)
   TextSurf, TextRect = text_objects('A bit Racey', largeText)
   TextRect.center = ((display_width/2),(display_height/2))
   gameDisplay.blit(TextSurf, TextRect)
   pygame.display.update()
   clock.tick(15)

全部代码：

import pygame
import time
import random

pygame.init()

white = (255,255,255)
black = (0,0,0)

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 things_dodged(count):
 font = pygame.font.SysFont(None, 25)
 text = font.render("Dodged:"+str(count), True, black)
 gameDisplay.blit(text,(0,0))

def things(thingx, thingy, thingw, thingh, color):
 pygame.draw.rect(gameDisplay, color, [thingx, thingy, thingw, thingh])

def car(x, y):
 gameDisplay.blit(carImg, (x,y))

def text_objects(text, font):
 textSurface = font.render(text, True, black)
 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_intro():
 intro = True

   TextRect.center = ((display_width/2),(display_height/2))
   gameDisplay.blit(TextSurf, TextRect)
   pygame.display.update()
   clock.tick(15)

def game_loop():
 x = display_width * 0.45
 y = display_height * 0.8
 x_change = 0

dodged = 0

gameExit = False

thing_startx = random.randrange(0, display_width)
 thing_starty = -600
 thing_speed = 7
 thing_width = 100
 thing_height = 100

while not gameExit:
   for event in pygame.event.get():
     if event.type == pygame.QUIT:
       pygame.quit()
       quit()
     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)

things(thing_startx, thing_starty, thing_width, thing_height, black)
   thing_starty += thing_speed

car(x,y)
   things_dodged(dodged)
   if x > display_width - car_width or x < 0:
     gameExit = True
   if thing_starty > display_height:
     thing_starty = 0 - thing_height
     thing_startx = random.randrange(0, display_width)
     dodged += 1
     thing_speed += 1
     thing_width += (dodged * 1.2)
   if y < thing_starty + thing_height:
     print('y crossover')
     if x > thing_startx and x < thing_startx + thing_width or x + car_width > thing_startx and x + car_width < thing_startx + thing_width:
       print('x crossover')
       crash()
   pygame.display.update()
   clock.tick(60)
#crash()
game_intro()
game_loop()
pygame.quit()
quit()
