pyxelでRPG風のものを作る(2)

前回作ったRPGもどきは移動しかできなかったのでプレイヤーの攻撃処理と敵を追加して、もう少しゲームらしくしていきます。以下に前回のリンクを張っておきます。

それでは始めていきます。目標はなるべくコードがごちゃらないように、そして今後の拡張性にも少し気を使ってみます。今回は攻撃処理を追加して、攻撃の座標を取得するところまでです。

   def __init__(self):
      
      #Player status
      self.Player = Player(8, 56)
      self.player_move = 0    
      self.atc_flug = False   
      self.atc_count = 0      
      self.p_atc_x = 0        
      self.p_atc_y = 0        
      
      #Map status
      self.stage_flug = 1     
      self.map_count_x = 1    
      self.map_count_y = 1    
      self.map_x = 0
      self.map_y = 0
      self.map_move = 0
      
      #System status
      self.game_start = False 
      self.game_over = False 
      
      pyxel.init(128,128)

      #Image read
      pyxel.load('C:/pyxel/image/pknights.pyxres')
      
      pyxel.run(self.update, self.draw)

まず、init関数に今回使う変数を追加します。atc_flugは攻撃をしているかの判定、atc_countは攻撃硬直時間、p_atc_xとp_atc_yは攻撃座標に使います。

   def update(self):
      if pyxel.btnp(pyxel.KEY_S):
        self.game_start = True
      if pyxel.btnp(pyxel.KEY_Q):
          pyxel.quit()
       
      #Player attack           
      if pyxel.btnp(pyxel.KEY_SPACE):
          self.atc_flug = True
          
      #Player controll
      self.Player_ctr()

update関数です。ここは変更はありません。攻撃処理はPlayer_ctrに持たせることとします。

   def draw(self):
      pyxel.cls(0)
      
      #Draw tilemap
      pyxel.bltm(0,0,0,0 + self.map_x,0 + self.map_y,16,16)
  
      #Draw player
      if self.atc_flug == True:
          if self.Player.player_m == 0:
              pyxel.blt(self.Player.player_x,self.Player.player_y,
                            0,0,16,8,8,14)
              pyxel.blt(self.Player.player_x+8,self.Player.player_y,
                            0,0,24,8,8,14)
          elif self.Player.player_m == 1:
              pyxel.blt(self.Player.player_x,self.Player.player_y,
                            0,8,16,8,8,14)
              pyxel.blt(self.Player.player_x-8,self.Player.player_y,
                            0,8,24,8,8,14)
          elif self.Player.player_m == 2:
              pyxel.blt(self.Player.player_x,self.Player.player_y,
                            0,16,16,8,8,14)
              pyxel.blt(self.Player.player_x,self.Player.player_y-8,
                            0,16,24,8,8,14)
          elif self.Player.player_m == 3:
              pyxel.blt(self.Player.player_x,self.Player.player_y,
                            0,24,16,8,8,14)  
              pyxel.blt(self.Player.player_x,self.Player.player_y+8,
                            0,24,24,8,8,14)
      else:
          if self.Player.player_m == 0:
                  pyxel.blt(self.Player.player_x,self.Player.player_y,
                            0,0,0+self.Player.player_m2*8,8,8,14)
          elif self.Player.player_m == 1:
              pyxel.blt(self.Player.player_x,self.Player.player_y,
                            0,8,0+self.Player.player_m2*8,8,8,14)
          elif self.Player.player_m == 2:
              pyxel.blt(self.Player.player_x,self.Player.player_y,
                            0,16,0+self.Player.player_m2*8,8,8,14)
          elif self.Player.player_m == 3:
              pyxel.blt(self.Player.player_x,self.Player.player_y,
                            0,24,0+self.Player.player_m2*8,8,8,14)
      
      #Draw title text
      if self.game_start == False:
         pyxel.cls(0)
         pyxel.text(35, 40, "PYXEL KNIGHTS", 7)
         pyxel.text(45, 70, "S = START ", 7)
         pyxel.text(45, 80, "Q = QUIT ", 7)
      else: #Draw player hp

         pyxel.text(20, 30, "GAME OVER!", 7)
         pyxel.text(80, 70, "R = RETRY ", 7)
         pyxel.text(80, 80, "Q = QUIT ", 7)

draw関数です。今回追加したatc_flugの値を条件にして、プレイヤーの描画を変えていきます。攻撃中はプレイヤーの方向に対応した上下左右のマスに攻撃描画をします。
また、前回に追加してプレイヤーのHPとゲームオーバー時の描画を追加しています。

　　　　　　　　　print(str(self.p_atc_x) + "," + str(self.p_atc_y))

Player_ctr関数です。攻撃処理のために if self.atk_flug == Trueから以下の部分を追加しました。
まずは、atc_countをカウントアップして攻撃処理を8フレーム持続するようにします。atc_count>8になった時点で、各種変数を0にして、atk_flugをFalseにします。
次に攻撃中の場合に攻撃座標を取得するようにします。player_mの値によって上下左右に分けて、プレイヤーの座標から8ずらします。
最後にprintを使ってコンソールで座標を見れるようにしておきましょう。
例えば初期位置の(8,56)で右を向いて攻撃すると、攻撃座標は(16,56)になります。

class Player:
  def __init__(self, x, y):
      self.player_x = x
      self.player_y = y
      self.player_h = 100
      self.player_d = 0
      self.player_m = 0
      self.player_m2 = 0
  def update(self, x, y):
      self.player_x = x
      self.player_y = y
      
      
  
App()

クラス部分には特に変更はありません。
