这篇文章主要为大家详细介绍了pygame游戏之旅的第8篇，教大家实现游戏中躲过障碍数量的计算，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
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()
