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 = screenself.game_settings = game_settingsself.image = pygame.image.load('images/PR/player.png')self.rect = self.image.get_rect()self.screen_rect = self.screen.get_rect()self.screen_center_pos = self.screen_rect.centerxself.rect.centerx = self.screen_rect.centerxself.rect.bottom = 380self.center = float(self.rect.centerx)self.moving_right = Falseself.moving_left = Falseself.player_moving = Falseself.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 = 0.0self.player_direction = 1#1为右，-1为左self.player_down = Falseself.player_up = Falseself.player_jump = Falseself.player_start_Y = 380#开始人物的高度self.player_Y = self.player_start_Yself.player_shooting = Falsedef update(self):if self.game_settings.player_is_alive:if self.moving_right and self.rect.right < self.screen_rect.right:if self.game_settings.boss_appear:self.center += self.game_settings.player_speedelif self.center > self.screen_center_pos:self.center += 0else:self.center += self.game_settings.player_speedif self.moving_left and self.rect.left > 0:self.center -= self.game_settings.player_speedself.rect.centerx = self.centerself.update_image_moving()else:self.update_die()def update_die(self):self.names = locals()self.players = []for self.i in range(1,3):self.names['player_image%s' %self.i] = pygame.image.load('images/PR/death%s.png' %self.i)self.players.append(self.names['player_image%s' %self.i])self.image = self.players[int(self.pos_d)]self.pos_d += 0.1if self.pos_d > 2.0:self.pos_d = 0.0self.game_settings.player_die_end = Truedef update_image_moving_direction(self,direction):#循环图片if self.player_shooting == True:self.names = locals()self.players = []for self.i in range(1,4):self.names['player_image%s' %self.i] = pygame.image.load('images/'+direction+'/shooting%s.png' %self.i)self.players.append(self.names['player_image%s' %self.i])self.image = self.players[int(self.pos_n)]self.pos_n += 0.1#射击时跑步速率if self.pos_n > 3.0:#射击时跑步有3个动作self.pos_n = 0.0else:self.names = locals()self.players = []for self.i in range(1,6):self.names['player_image%s' %self.i] = pygame.image.load('images/'+direction+'/player%s.png' %self.i)self.players.append(self.names['player_image%s' %self.i])self.image = self.players[int(self.pos_i)]self.pos_i += 0.1#跑步速率if self.pos_i > 5.0:#跑步有5个动作self.pos_i = 0.0def 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.names1['player_image%s' %self.j] = pygame.image.load('images/'+direction+'/jump%s.png' %self.j)self.players1.append(self.names1['player_image%s' %self.j])self.image = self.players1[int(self.pos_j)]self.pos_j += 0.3#跳跃旋转速率if self.pos_j > 4.0:#跳跃有4个动作self.pos_j = 0.0else: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.centerdef get_player_down(self):self.get_player_state('down')self.rect.bottom = self.player_start_Yself.screen.blit(self.image,self.rect)def get_player_up(self):self.get_player_state('up')self.rect.bottom = self.player_start_Yself.screen.blit(self.image,self.rect)def get_player_jump(self):self.get_player_state('jump1')self.rect.bottom = self.player_Yif 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_velif self.player_Y > self.player_start_Y:self.player_jump = Falseself.player_Y = self.player_start_Yself.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.image = pygame.image.load('images/PL/player.png')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.centerself.rect.bottom = self.player_start_Yself.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.centerxself.game_settings.player_is_alive = True

实现效果如下：

操作说明：

• A：向左

• D：向右

• W：跳起

• S：趴下

• J：射击

• P：退出程序

目前游戏还是比较初级的版本，有兴趣的小伙伴可以自行修改完善。
