フォントをレンダリングした後のサスペンダーのドロップ数

Question

私はこのフラットな鳥のような単純なサイドスクロールゲームで作業しており、音楽とすべてのスプライトを追加するとスムーズに動いていました。しかしフォント（ttf）ゲームはfpsの急激な低下を遂げました。 助けてください？ここで

は私のrenderメソッドです：

@Override 
public void render(SpriteBatch sb) { 

    sb.setProjectionMatrix(cam.combined); 
    sb.begin(); 
    sb.draw(actualGamebg, cam.position.x - (cam.viewportWidth/2), 0); 
    sb.draw(bird.getTexture(), bird.getPosition().x , bird.getPosition().y); 
    for(Tube tube: tubes) { 

     sb.draw(tube.getTopTube(), tube.getPosTopTube().x, tube.getPosTopTube().y); 
     sb.draw(tube.getBottomTube(), tube.getPosBottomTube().x, tube.getPosBottomTube().y); 
    } 
    sb.draw(ground,groundPos1.x,groundPos1.y); 
    sb.draw(ground,groundPos2.x,groundPos2.y); 

    font24.draw(sb,SCORE,24,100); 
    sb.end(); 

}

あなたはttfファイルを読んでおり、フレームごとに新しいBitmapFontオブジェクトを作成しています。 update（）でfontGenerator（）を呼び出さないでください。コンストラクタで一度呼び出す。
