私が試したこと：

そこで、プレイヤーが移動するたびに、空のフロア グリッドの 1 つを「折りたたむ」ようにしたいと考えました。 しかし、崩壊は、単一の空のグリッドが崩壊し、ゲーム端末で「X」として表される方法で発生する必要がありました. フロア グリッドが毎回新しい位置で折りたたまれるように機能する必要がありました。 プレイヤーがいる場所、ゴールがある場所、または崩壊した床がすでに存在する場所ではありません。

void move_player(char board[][SIZE], int *player_row, int *player_col, int move_row, int move_col) {
    int new_row = *player_row + move_row;
    int new_col = *player_col + move_col;

    if (new_row < 0 || new_row >= SIZE || new_col < 0 || new_col >= SIZE) {
        printf("Invalid move\n");
        return;
    }

    if (board[new_row][new_col] == EMPTY) {
        // Check if the empty space can collapse
        if (board[new_row][new_col] != COLLAPSED && (new_row != *player_row || new_col != *player_col) && (new_row != GOAL_ROW || new_col != GOAL_COL)) {
            printf("A grid collapses!\n");
            board[new_row][new_col] = COLLAPSED;
        }
        else {
            printf("Invalid move\n");
            return;
        }
    }

    if (new_row == GOAL_ROW && new_col == GOAL_COL) {
        printf("Congratulations! You have reached the goal.\n");
        exit(0);
    }

    board[*player_row][*player_col] = EMPTY;
    board[new_row][new_col] = PLAYER;
    *player_row = new_row;
    *player_col = new_col;
}

この関数を作成し、メイン ファイルにインポートしようとしましたが、不明な型名エラーが発生し続けました。 不明な名前の種類のエラーは、”import collapse” に対するものです。collapse.c は、メイン ファイルにインポートしたいセカンダリ ファイルの名前です。
