I made a simple game with Javafx ①

"Let's find happiness game" (unfinished)

`sample.java`


package happy_unhappy_game;

import java.util.Random;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.AnchorPane;
import javafx.scene.layout.TilePane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;


	public class Sample extends Application {

		public static void main(String[]args) {
			launch();
		}

		 public static Scene scene1 = null;
		 public static Scene scene2 = null;

		 public static String txt=null;
		 public static String txt2=null;
    	 public static Label status=new Label();
    	 public static Button btn2 =null;
    	 public static VBox root=new VBox();
    	 public static TilePane pane=new TilePane();



    @Override
    public void start(Stage stage) throws Exception {

    	stage.setTitle("main");
    	stage.setWidth(380);
    	stage.setHeight(500);
    	  //Creating a stage
    	initScene2(stage);
    	initScene1(stage);

    	stage.setScene(scene1);
    	stage.show();
    }

    public static void initScene1(Stage stage){
    	stage.setWidth(380);
    	stage.setHeight(500);
    	stage.setTitle("1");

    	Random rnd=new Random();

    	Button button[]=new Button[144];
    	for(int i=0;i<144;i++) {
    		button[i]=new Button("Spicy");
    		button[i].setPrefWidth(30);
    		button[i].setPrefHeight(30);
    		String txt=String.format("that is\"Spicy\"is.");
    		button[i].setOnAction(event->status.setText(txt));
    	}

    		int number=rnd.nextInt(144);
			button[number]=new Button("Fortunately");
    		button[number].setPrefWidth(30);
    		button[number].setPrefHeight(30);
    		txt2=String.format("\"Fortunately\"Was clicked.");
    		button[number].setOnAction(event->push(stage));

    	pane=new TilePane();
    	pane.getChildren().addAll(button);

    	root=new VBox();
    	root.getChildren().addAll(pane,status);

    	scene1=new Scene(root);
    }


    public static void initScene2(Stage stage) {
    	stage.setWidth(380);
    	stage.setHeight(500);
    	stage.setTitle("2");

    	Button btn = new Button("Scene change completed! !! !!");
    	    btn.setPrefWidth(100);
    	    btn.setPrefHeight(50);
    	    btn.setOnMouseClicked(event -> setScene2(stage,scene1));

    	    AnchorPane root = new AnchorPane();
    	    root.getChildren().add(btn);
    	    scene2 = new Scene(root);

    }

    public static void push(Stage stage) {
    	status.setText(txt2);
    	btn2 = new Button("next");
		btn2.setPrefWidth(100);
		btn2.setPrefHeight(50);
		btn2.setOnMouseClicked(event -> setScene(stage,scene2));
    	root.getChildren().addAll(btn2);
    }

    public static  void setScene(Stage stage,Scene changeScene) {
        stage.setScene(changeScene);
        stage.show();
     }

    public static  void setScene2(Stage stage,Scene changeScene) {
	    stage.setScene(changeScene);
	    stage.show();
	  }

 	}

Outline of the game and problems at this stage

A game that searches for one "good luck" button from a large number of "spicy" buttons. At the moment, I am struggling because the screen transition is not good. In the future, we have added a time limit and a counting function.
