私は Java で単純な sideScroller を作成しようとしていますが、これまでのところ私のゲームは期待どおりに動作しますが、一時停止メニューを作成してメイン メニューなどに移動する方法がわかりません (作成方法についてはまったくわかりません)。その学科の主なマヌ）それが最良のアイデアだと思いますか？これは私のゲームの関連コードです。このパネルはフレーム内で呼び出されます。

問題は、クラスの Background が直接描画する場所であることです。通常、ゲームはすべてのフレームなどを処理しますが、次のように、メイン ゲームが呼び出すある種の GameState オブジェクトがあります。

public void update() {
    if (pause) {
        gameState = pauseState;
    } else {
        gameState = playState;
    }

    gameState.update();
}

@Override
public void paint(Graphics g) {
    super.paint(g);
    Graphics2D g2d = (Graphics2D) g;
    gameState.paint(g2d)
}

アイデアは、必要な数の gameStates を持つことができるということです。Update、Paint、Initialize、および Dispose (またはこのようなもの) のメソッドを提供するインターフェイス GameState を作成するだけです。次に、Play、Pause、MainMenu、SaveGameMenu など、すべての種類の GameStates を持つことができ、それぞれが更新と描画を担当します。

GameStates を交換するロジックを処理するメイン クラス (ゲーム ループがある場所) です。
