滑雪者角色控制类实现

# 定义一个雪人类
import pygame
from settings import Settings

my_set = Settings()
skier_images = ['./skier_crash.png', './skier_down.png', './skier_left1.png', './skier_left2.png',
  './skier_right1.png', './skier_right2.png', ]
down_image = pygame.image.load(skier_images[1])
# 雪人初始位置
begin_top = 0
begin_left = my_set.screen_width / 2 - down_image.get_width() / 2

class Skier(pygame.sprite.Sprite):
 def __init__(self,speed):
 pygame.sprite.Sprite.__init__(self)
 '''
 :param image:指的是图片路径
 :param rect:位置
 :param down_speed:是往下的速度
 '''
 self.image = pygame.image.load(skier_images[1])
 self.rect = self.image.get_rect()
 self.rect.top = begin_top # 雪人初始位置
 self.rect.left = begin_left
 # 移动速度
 self.speed = speed
 #场景生成时间 也就是速度
 self.time_set = 40
 #根据按键事件来移动
 def update(self, pressed_keys):
 # 按键事件
 if pressed_keys[pygame.K_LEFT] or pressed_keys[pygame.K_a]:
  if self.rect.left > 0:
  self.image = pygame.image.load(skier_images[2]).convert()
  self.rect.left -= self.speed
 elif pressed_keys[pygame.K_RIGHT] or pressed_keys[pygame.K_d]:
  if self.rect.left < my_set.screen_width - self.image.get_width():
  self.image = pygame.image.load(skier_images[4]).convert()
  self.rect.left += self.speed
 if pressed_keys[pygame.K_UP] or pressed_keys[pygame.K_w]:
  if self.rect.top > 0 :
  self.image = pygame.image.load(skier_images[1]).convert()
  self.rect.top -= self.speed
 elif pressed_keys[pygame.K_DOWN] or pressed_keys[pygame.K_s]:
  if self.rect.top < my_set.screen_height - self.image.get_height():
  self.image = pygame.image.load(skier_images[1]).convert()
  self.rect.top += self.speed
 if not (pressed_keys[pygame.K_LEFT] or pressed_keys[pygame.K_a] or pressed_keys[pygame.K_RIGHT] or
  pressed_keys[pygame.K_d] or pressed_keys[pygame.K_UP] or pressed_keys[pygame.K_w] or
  pressed_keys[pygame.K_DOWN] or pressed_keys[pygame.K_s]):
  self.image = pygame.image.load(skier_images[1]).convert()

障碍物（树与旗子）生成逻辑

import pygame
from random import randrange
from settings import Settings

my_set = Settings()
# 定义一个场景类
class TreeFlagClass(pygame.sprite.Sprite):

 def __init__(self,speed,treeFlag): #传入两个参数，初始速度和bool值树或旗子
 pygame.sprite.Sprite.__init__(self) #父类的初始化方法要调用
 '''
 :param image =图片
 :param type 判断是树还是旗子
 :param speed 速度
 '''
 if treeFlag:
  self.image = pygame.image.load('./skier_tree.png')
  self.type = 'tree'
 else:
  self.image = pygame.image.load('./skier_flag.png')
  self.type = 'flag'
 self.rect = self.image.get_rect()
 self.rect.top = self.rect.height + my_set.screen_height
 self.rect.centerx = randrange(my_set.screen_width - self.rect.width) + self.rect.width / 2
 self.speed = speed

 def update(self, *args):
 self.rect.top -= self.speed
 if self.rect.top < -self.rect.height:
  self.kill()

系统参数配置类设计

class Settings(object):
 def __init__(self):
 #这是一个设置类，用来管理游戏的外观
 self.screen_width = 600
 self.screen_height = 800
 self.bg_color = [255,255,255]
 self.name = 'skier'
