今天分享一个经典小游戏魂斗罗的 Python 版实现。部分代码实现如下:
class Game_Player():  def __init__(self,game_settings,screen):
  self.screen = screen   self.game_settings = game_settings
  self.image = pygame.image.load('images/PR/player.png')

  self.center = float(self.rect.centerx)   self.moving_right = False
  self.moving_left = False   self.player_moving = False
  self.pos_i = 0.0#跑步画面改变速度   self.pos_j = 0.0#跳跃的改变初始速度   self.pos_n = 0.0#射击
  self.pos_d = 0.0   self.player_direction = 1#1为右,-1为左
  self.player_down = False   self.player_up = False   self.player_jump = False

     self.center += self.game_settings.player_speed
    elif self.center > self.screen_center_pos:      self.center += 0     else:
     self.center += self.game_settings.player_speed
   if self.moving_left and self.rect.left > 0:
    self.center -= self.game_settings.player_speed

 def update_image_jump(self,direction):#循环图片
  if self.game_settings.player_is_alive:    if self.player_jump == True:
    self.names1 = locals()     self.players1 = []     for self.j in range(1,5):

   self.update_die()  def update_image_moving(self):   if self.player_moving:
   if self.moving_right:     self.update_image_moving_direction('PR')#PR是向右的图片
   elif self.moving_left:     self.update_image_moving_direction('PL')
 def get_player_state(self,player_state):#检测player的状态是否为趴下,向上,跳跃等
  if self.player_direction == 1:
   self.image = pygame.image.load('images/PR/'+player_state+'.png')
  if self.player_direction == -1:
   self.image = pygame.image.load('images/PL/'+player_state+'.png')
  self.rect = self.image.get_rect()   self.rect.centerx = self.center
 def get_player_down(self):   self.get_player_state('down')

  self.get_player_state('jump1')   self.rect.bottom = self.player_Y
  if self.game_settings.jump_vel < 0:
   self.game_settings.jump_vel += 0.6#跳跃上升的增加的速率
  elif self.game_settings.jump_vel > 0:
   self.game_settings.jump_vel += 0.8#跳跃下降增加的速率
  self.player_Y += self.game_settings.jump_vel
  if self.player_Y > self.player_start_Y:    self.player_jump = False
   self.player_Y = self.player_start_Y
   self.game_settings.jump_vel = -14.0#恢复跳跃开始的速度
   if self.player_direction == 1:
    self.image = pygame.image.load('images/PR/player.png')
    self.reset_player()    if self.player_direction == -1:

    self.reset_player()   if self.player_jump == True:#判断是否处于跳跃状态来决定是否旋转跳跃的图像
   if self.player_direction == 1:     self.update_image_jump('PR')
   if self.player_direction == -1:     self.update_image_jump('PL')
  self.screen.blit(self.image,self.rect)  def reset_player(self):
  self.rect = self.image.get_rect()   self.rect.centerx = self.center

  self.screen.blit(self.image,self.rect)  def blitme(self):
  if self.player_jump:    self.get_player_jump()   elif self.player_down:
   self.get_player_down()   elif self.player_up:    self.get_player_up()
  else:    self.reset_player()  def revive_player(self):
  self.center = self.screen_rect.centerx
  self.game_settings.player_is_alive = True
实现效果如下:

魂斗罗
