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')

    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()
