C#で作っているゲームはSquare Chaseです。移動する前に、ブロックの上にマウスを置いてクリックします。バックグラウンドでタイマーがカウントダウンし、ブロックの「タグ」ごとにスコアが 1 ずつ上がります。XNA 4.0 Game Development by Example でプロジェクトを実行できます。これは 2010 C# で、プロジェクト タイプは Windows ゲーム (4.0) です。
今、私はそれに余分なものを追加したいと思います。ブロックをクリックするたびに 5 秒の時間を取りたいのですが、それが機能しているかどうかわからないので、残り時間を表示する必要があります。四角を打つたびに小さくしたい。
コード：（更新とifステートメントの下で、時間の減算はすでに行っていますが、表示して動作を確認したいと思います）ありがとう
沈む方法を見つける必要があり、大きな画像では、画面にフロートを表示する方法を知る必要があります。
