そこで、Visual Studio 2012 at School で完璧に動作するこのプログラムを作成しようとしています。
しかし、私が家にいるとき、このThrown ExceptionエラーがPublic Game1().
プログラムを実際に実行して終了できるように、誰かがこれを手伝ってくれることを願っています。
コール スタックは次のとおりです。
System.NullReferenceException: オブジェクト参照が Microsoft.Xna.Framework.OpenTKGameWindow.Initialize () [0x00000] のオブジェクトのインスタンスに設定されていません。 0 at Microsoft.Xna.Framework.OpenTKGamePlatform..ctor (Microsoft.Xna.Framework.Game game) [0x00000] in :0 at Microsoft.Xna.Framework.GamePlatform.Create (Microsoft.Xna.Framework.Game game) [0x00000] ] in :0 at Microsoft.Xna.Framework.Game..ctor () [0x00000] in :0 at MonoGameTest.Game1..ctor () [0x00023] in /Users/sebnabt/Projects/MonoGameTest/MonoGameTest/Game1.cs :38 at MonoGameTest.Program.Main () [0x00001] in /Users/sebnabt/Projects/MonoGameTest/MonoGameTest/Program.cs:19

最新のエラー:
わずかに機能するようになったように見えますが、次の基本テンプレートでエラーが発生しています。logoTexture = Content.Load<Texture2D>("logo");
