pygame游戏之旅 计算游戏中躲过的障碍数量


						本文为大家分享了pygame游戏之旅的第8篇，供大家参考，具体内容如下

定义一个计数函数：





def things_dodged(count):

 font = pygame.font.SysFont(None, 25)

 text = font.render("Dodged:"+str(count), True, black)

 gameDisplay.blit(text,(0,0))



在游戏循环中加入计数，然后增加一些游戏难度，例如加速障碍，增加障碍的宽度：







dodged += 1

thing_speed += 1

thing_width += (dodged * 1.2)



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_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()
