c++ - エラー c2660 および c2061 C++

Question

次のエラーの処理に問題があります。

c2660: c:\users\lukas plaehn\desktop\oop\sokoban\sokoban\main.cpp(126): エラー C2660: 'CPlayer::moveUp': 関数は引数を 1 つ取りません

c2061: c:\users\lukas plaehn\desktop\oop\sokoban\sokoban\player.h(10): エラー C2061: 構文エラー: 識別子 'CMaze'

私がやろうとしているのは、オブジェクトをヘッダー ファイルのパラメーターとして渡すことです。私も参照して試してみましたが、うまくいきません。CMazeどういうわけか、コンパイラは、ヘッダー ファイル内の型の宣言を許可していませんCPlayer。

    void moveUp(CMaze maze);
    void moveDown(CMaze maze);
    void moveLeft(CMaze maze);
    void moveRight(CMaze maze);

Answer 1

これは、player.h から迷路ヘッダーを含めていないという事実と関係があると思います...これは、値で渡す場合 (不要なコピーが発生するため悪いことです)、関数CMaze オブジェクトを使用したいにもかかわらず、CMaze オブジェクトについて何も知りません。

CMaze をポインターまたは参照として渡せば、問題は解決すると思います。ただし、これを行うことにより、関数内で CMaze を後で変更すると、渡された CMaze も変更されることに注意する必要があります。

Answer 2

CMaze を前方宣言し、参照渡しすると、c2061 が処理されます。

class CMaze;
class CPlayer : public CBlocks
{
    public:
    CMaze * m;
    CPlayer(void);
    CPlayer(char sym, int x, int y, CMaze & mz);
    ~CPlayer(void);
    void moveUp(CMaze & maze);
    void moveDown(CMaze & maze);
    void moveLeft(CMaze & maze);
    void moveRight(CMaze & maze);
