Question

我的第一个场景正常但是当我尝试使用第二个场景时它会崩溃。我想我做错了什么？说我喜欢设置Root，但尝试了很多不同的东西，没有用，不断崩溃

public void start(Stage primaryStage) throws Exception {
        FXMLLoader loader = new FXMLLoader(getClass().getResource("visual.fxml"));
        Parent root = (Parent) loader.load();
        ctrl = loader.getController();
        primaryStage.setTitle("World of Snopscraft");
        primaryStage.setScene(new Scene(root, 1024, 768));
        primaryStage.show();
        ctrl.setPrevStage(primaryStage);
}

控制器：

boolean canSetCard=false;
int selectedCard;

Game game;
Stage primaryStage;

@FXML
public void initialize() {

    game=new Game(this);
    game.start();
};

public void setScene() throws IOException {
    Parent root = FXMLLoader.load(getClass().getResource("end.fxml"));
    primaryStage.setScene(new Scene(root, 1024, 768));
    primaryStage.show();

}

public void setPrimaryStage(Stage primaryStage) {
    this.primaryStage = primaryStage;
}

public void playCard1(){
    try {
        setScene();
    } catch (IOException e) {
        e.printStackTrace();
    }
    //if(game.getCanPlay()==true)game.play(0);

}

编辑：添加了错误代码和控制器错误：

Javafx.fxml.LoadException: Root hasn't been set. Use method setRoot() before load.
