JavaFX Scene wechseln unter FX

Posted on 10:13 by verona
Heyho liebe Java'ler,

ich arbeite mich derzeitig in JavaFX ein und versuche relativ banale Dinge zu programmieren , verstehe aber derzeitig die Funktionsweise von FX nicht.

Derzeitig ist mein Problem ,dass ich 1 Menü habe das beim Klick auf "Spiel Starten" ein weiteres Menü mit "Singleplayer " und "Multiplayer" öffnen soll, hierbei funktioniert aber der scene wechseln nicht.

Java Code:


    

  1. 

    package team;
    

    2. 

  2. 

     
    

    3. 

  3. 

    import javafx.application.Application;
    

    4. 

  4. 

    import javafx.fxml.FXML;
    

    5. 

  5. 

    import javafx.fxml.FXMLLoader;
    

    6. 

  6. 

    import javafx.stage.Stage;
    

    7.

    import javafx.scene.Parent;

    import javafx.scene.control.Button;
    

    10. 

  10. 

    import javafx.scene.layout.BorderPane;
    

    11. 

  11. 

     
    

    12. 

  12. 

     
    

    13. 

  13. 

    public class Menu extends Application {
    

    14. 

  14. 

     
    

    15. 

  15. 

    @Override
    

    16. 

  16. 

    public void start(Stage primaryStage) {
    

    17. 

  17. 

     
    

    18. 

  18. 

    // Showing Menu
    

    19. 

  19. 

     
    

    20. 

  20. 

    try {
    

    21. 

  21.

              </font></Button>

        </children>

      </GridPane>

  </children>

</AnchorPane>


Es ist derzeitig also wie folgt aufgebaut: Wird auf "Start Game" geklickt wird ein Integer Wert quasi als Leitwert der Szene auf 1 gesetzt , welches dann in der Start Methode das alles wechseln sollte.



Hoffe ihr könnt mir helfen..



Mit freundlichen Grüßen
