今後のプロジェクトで使用するために、独自のシンプルなゲームエンジンを作成しています。基本クラスRenderObjectを拡張する一連のオブジェクトを格納するワールドオブジェクトがあります。
RenderObjectには、スケール回転位置の滑らかなシェーディングなどが含まれ、すべての拡張クラスに独自のメソッドrender（）を実装するように強制します。
私の世界をナビゲートするために、FPSスタイルのカメラコントロールセットアップがあります。これは、system.out.println（）を介してテストし、ピッチとヨーをチェックして、正しく機能しています。
ただし、どのオブジェクトもレンダリングされていません。私のワールドオブジェクトには、ワールド内のすべてのオブジェクトを循環し、それらのrender（）関数を呼び出すrenderObjects（）というメソッドがあります。 修正済み-新しい問題...特定の場所でランダムに飛び回る4つの2x2ピクセルドットを取得しています。次に、マウスを動かすと、クラスター全体が移動します。ゲームごとにonUpdate（）メソッドが呼び出され、lookThrough（）が呼び出されます。
