這篇文章主要為大家詳細(xì)介紹了pygame游戲之旅的第8篇，教大家實(shí)現(xiàn)游戲中躲過(guò)障礙數(shù)量的計(jì)算，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文為大家分享了pygame游戲之旅的第8篇，供大家參考，具體內(nèi)容如下

定義一個(gè)計(jì)數(shù)函數(shù)：

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

在游戲循環(huán)中加入計(jì)數(shù)，然后增加一些游戲難度，例如加速障礙，增加障礙的寬度：

dodged += 1
thing_speed += 1
thing_width += (dodged * 1.2)

全部代碼：

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_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_loop()
pygame.quit()
quit()
