私は、プレーヤーといくつかの敵を特徴とする小さなコンソールベースのゲームのためのいくつかのコードを書いてきました。これまでのところ私は自分のプレーヤークラスのメソッドの1つしか書いていません。 プレーヤークラスは、entityという親クラスの子クラスで、敵クラスと呼ばれる子クラスもあります。 player.cppのメソッドでvoid player::takeInput()の値this->xCoordinateを変更しようとしました。ここで、int xCoordinateはエンティティクラスのパブリックメンバーです。私はこのコードをコンパイルするたびに、私はエラーを与えています：エラー変数を取得することができません
include\entity.h line 31 error: 'int entity::xCoordinate' is inaccessible
C:\Users....\ line 72 error: 'error within this context'
注ライン72上のコードがあること：
int newX = this->xCoordinate;
このエラーは、私が作る他の（多くの）呼び出しのすべてに対して繰り返されますthis->xCoordinateまたはthis->yCoordinateになるたびに、entity.hの31行目のエラーと「このコンテキスト内のエラー」というエラーが発生します。
このエラーは、クラスが互いに継承する方法と関係があると思います。私が見つけることができた唯一の解決策は、メンバーが私的にラベル付けされている問題を解決することでした。
私はスーパー経験豊富なプログラマーではなく、自分自身を中間者として評価するだけなので、いくつかのミスを含んでいればコードをお試しください！
ありがとうございました！ はここでは、ソースコードです、私はまだプロジェクトの残りの部分の上にあまりにも多くの仕事を行っていないことに注意してください。

enemy.h：
enemy.cppにはまだコードがありません。 私はCode :: BlocksでGNUコンパイラを使用しています ありがとう！あなたのenemyクラスがentityのデフォルト（プライベート）の継承を使用している
'this->'を削除してみてください...必要ありません –
'class enemy：entity'継承のタイプを指定するのを忘れました。デフォルトはプライベートです。ベースクラスのメンバーにアクセスするために 'public'を追加する –
