プレーヤーが移動するたびにテキスト変数を更新しようとしています。問題は、私がそうするたびに、新しい文字列が前の文字列の上に現れることです。ゲームウィンドウのサイズを変更または拡大すると、文字列が正常に表示されます。SFMLでテキストを更新する
問題プログラム状態：
拡張状態（所望の状態）：私は、問題がどこにあるかのコードを提供下記
。私のコードは最高ではないかもしれませんが、私はsfmlを学び始めたので、時には結果を得るために少しハードコードすることがあります。私がこれを終えるとすぐに、より良いプログラミング実践でアプリケーション全体を書き直すつもりです。上記の文字列が処理される場所は、void handle_plmove_request（game_packet packet、listen_parameters param）およびvoid render_graphics（...）およびint main（）にあります。私は（）の主にテキスト変数を作成し、関数listen_to_server（）

概要を実行するスレッドに引数として渡す：私はちょうどそれを変更し、それを再描画することにより、テキストを更新しています。
問題は解決しましたが、今は両方のクライアントの間に遅れを感じることができます。 clear（）関数を使用する前に、両方のクライアントが完全に同期していました。 – KingMetin2
@ KingMetin2ネットワークの部分をチェックしていませんでしたが、それは起こりません。スコアの後ろに黒いテーブルを描くこともできますが、それは潜在的な問題を隠すだけです。 – Mario
@ KingMetin2 'sf :: Time one_millisecond = sf :: milliseconds（10）;' - うそ！もっと真剣に、私はあなたのコードで眠ることはありません。 SFMLはVSYNCを使用していますか、できるだけ早く実行しているゲームですか？それは2つの異なるマシン間のタイミングの違いを説明するかもしれません。 – Quentin
