pyxelでRPG風のものを作る(4)
前回で敵に対する攻撃判定まで実装できたので、今回はプレイヤーのダメージ判定を作ります。前回の記事を以下に貼っておきますので、よろしければご覧ください。
今回はあまり修正部分がないので、変更があった部分のみ取り上げて、最後にソース全体を載せようと思います。
def update(self):
if pyxel.btnp(pyxel.KEY_S):
self.game_start = True
if pyxel.btnp(pyxel.KEY_Q):
pyxel.quit()
#Player attack

#Enemy Hit-check

#Enemy creation
if self.map_move == 1:

for i in range(enemy_kazu):
new_enemy = Enemy1(enemy_x_1[i]*8, enemy_y_1[i]*8)
self.enemys.append(new_enemy)
self.map_move = 0 まずはupdate関数の修正から行います。と言っても、self.Dmg_chk()でプレイヤーのダメージ判定を呼び出すだけです。Dmg_chk関数は後に作成します。

self.Player.player_d = 1
if self.Player.player_h <= 0:
self.game_over = True今回新規に作成したDmg_chk関数です。基本的には前回の攻撃判定と同じように考えます。プレイヤー座標が敵の範囲内にあるかを判定し、範囲内の場合は体力を1減らし（self.Player.player_h = self.Player.player_h - 1）、ダメージ判定を付与します（self.Player.player_d = 1）。プレイヤー体力が0以下なった場合はゲームオーバーとします。
全てつなげたソースは以下の通りです。

App()とりあえず、これで敵への攻撃とプレイヤーへのダメージがそろいました。後は敵が動くようになれば結構ゲームっぽくなる気がします。
次回は敵を動かす処理を作っていきます。ここまで読んでいただき、ありがとうございました。
