pyxelでRPG風のものを作る(5)
前回までで敵への攻撃とプレイヤーへのダメージ判定が実装できました。今回は敵を動かす処理を実装して、さらにゲームらしくしていきたいと思います。前回の記事を以下に貼っておきますので、よろしければご参照ください。
敵の行動パターンは複雑な方がゲームとしては面白そうですが、最初から無理はせずなるべく簡単に作っていきたいと思います。今回の敵の動きとしては「一定範囲内にプレイヤーが近づいた場合に追いかけていく」ものとします

self.map_move = 0 update関数に今回新規作成するEnemy_ctr関数を呼び出す処理を追加します。敵の動作はこの関数内で制御します。
加えて、ゲームオーバーになった際にリトライできるようにRキーにリトライ用のRetry関数を呼び出す動作を追加します。

self.enemy_move = 0Enemy_ctr関数です。敵の動作を制御します。enemy_moveを毎フレームごとにカウントアップしていって40に達したら敵を動かします。
enemy_pos_xとenemy_pos_yにタイルマップで敵自身が今どのマスにいるのかの情報を入れます。これは、敵が移動不可のタイルに入らないようにするために使います。
enemy_pos_x2とenemy_pos_y2は敵とプレイヤーとの座標の差を入れる変数です。これを使って敵を上下に動かすか左右に動かすか判断させます。
if (abs(enemy_pos_x2) < 35 and abs(enemy_pos_y2) < 35):の条件文は敵とプレイヤーの距離が35以下の場合にTrueになります。この距離が敵の認知距離になります。敵がプレイヤーを認知した場合はenemy_pos_x2とenemy_pos_y2の値を比較して上下か左右に移動方向を決めます。その後は上下の場合はenemy_pos_y2が正の値なら下、負の値なら上に、左右の場合はenemy_pos_x2が正の値なら右、負の値なら左に移動させます。移動の向きによってenemy_mの値を変化させて描画時に参照するようにします。

敵も動くようになって結構ゲームらしくなってきた気がします。ただ、今のところ敵の出現位置が1パターンしかないので、次回はタイルマップごとに敵を場所を調整できるようにしていきたいと思います。
ここまで読んでいただきありがとうございます！
