Sudden Drop in fps nach dem Rendern einer Schriftart

Question

So arbeite ich in diesem einfachen Side Scrolling-Spiel wie flappy Vogel und das Spiel lief reibungslos, wenn ich die Musik und alle Sprites hinzugefügt.Aber wenn ich font (ttf) hinzugefügt, um die Spiel hatte einen abrupten Rückgang der fps und es lag viel hinterher. Irgendwelche Hilfe bitte?

Hier ist meine Render-Methode:

@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(); 

}

Do lassen Sie mich wissen, wenn Sie weitere Informationen und Dank benötigen. Cheers

Sie lesen die ttf-Datei und erstellen ein neues BitmapFont-Objekt für jeden Frame. Rufen Sie fontGenerator() nicht in update() auf. Nennen Sie es einmal im Konstruktor.
