Moin Leute,
ein neuer Tag eine neue Frage.
Bin gerade dabei eine GUI für ein Brettspiel zu schreiben und arbeite gerade an meiner letzten Scene.
Die Scene soll die aktuelle Position der Spieler anzeigen. Jedes mal wenn gewürfelt wird , soll der Spieler versetzt werden.
Meine FXML ist folgendermaßen aufgebaut.
Java:
<AnchorPane prefHeight="600.0" prefWidth="700.0" xmlns="http://javafx.com/javafx/8.0.111" xmlns:fx="http://javafx.com/fxml/1" fx:controller="Controller">
   <children>
      <VBox alignment="CENTER" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
         <children>
            <HBox alignment="CENTER" prefHeight="520.0" prefWidth="700.0">
               <children>
                  <GridPane alignment="CENTER" gridLinesVisible="true" prefHeight="509.0" prefWidth="702.0">

Ich habe eine Klasse Spieler , in dem die Position des Spielers gespeichert wird.
Wie ist es möglich die Circle (repräsentieren Spieler) nach jedem Wurf zu versetzten?
Ist das Konstrukt von GridPane-Rectange-Circle überhaupt dafür geeignet?
Hatte im ersten Versuch GridPane-Pane-Circle.

Gruß
 
Ich versuche es die ganze Zeit zu schnallen, aber ich komm nicht draus. Die Rectangles sind Spielfelder?
Wenn ja: Nimm ein Layout (ich persönlich würde StackPane verwenden) und füge einen Circle jeweils dem StackPane im Grid hinzo, wo ein Spieler sein soll...
Wie gesagt: Ich verstehe den Text schon nicht ganz, daher sehe ich auch kein echtes Problem (jedenfalls in meiner Interpretation deiner Frage).
