Today, I'd like to share a classic little game soul duel Python Version implementation . Part of the code is implemented as follows :
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.screen_center_pos = self.screen_rect.centerx
  self.rect.centerx = self.screen_rect.centerx   self.rect.bottom = 380
  self.center = float(self.rect.centerx)   self.moving_right = False
  self.moving_left = False   self.player_moving = False

  self.player_shooting = False  def update(self):
  if self.game_settings.player_is_alive:
   if self.moving_right and self.rect.right < self.screen_rect.right:

     self.center += self.game_settings.player_speed

 def get_player_state(self,player_state):# testing player Is the state of lying down , Upward , Jump, etc
  if self.player_direction == 1:

  else:    self.reset_player()  def revive_player(self):
  self.center = self.screen_rect.centerx
  self.game_settings.player_is_alive = True
The results are as follows :

Contra

Operating instructions :

*
A: towards the left

*
D: towards the right

*
W: Jump

*
S: Get down

*
J: Shooting

*
P: Exit program

At present, the game is still a relatively primary version , Interested partners can modify and improve themselves .
