JavaFx buttons click in order then play - javafx

Question

I am looking to have buttons play in the order in which they are clicked. For example, if I click buttons 3, 4, and 6 I would like to then click a "play" button and this button then clicks the same pattern I clicked.

Answer 1

This piece of code makes it looks like the button was pressed
button.arm();
PauseTransition pause = new PauseTransition(Duration.seconds(0.5));
pause.setOnFinished(e -> {
button.disarm();
});
pause.play();
If you want the button to actually fire not just look like it did then add button.fire(); after the button.disarm();
Then you just need to record the buttons that are pressed

Answer 2

Here is a crude example of how to implement this. TimeLine and SequentialTransitions are the key. Comments are in the code.
import java.util.ArrayList;
import java.util.List;
import javafx.animation.KeyFrame;
import javafx.animation.SequentialTransition;
import javafx.animation.Timeline;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.ToggleButton;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
import javafx.util.Duration;

public class JavaFXApplication57 extends Application
{
#Override
public void start(Stage primaryStage)
{
List<ToggleButton> order = new ArrayList();//The buttons will be added to see ArrayList as they are pressed. ArrayList maintains order
ToggleButton btn4 = new ToggleButton();
btn4.setText("btn4");
btn4.setOnAction(actionEvent ->
{
btn4.setSelected(false);//When you selected a ToggleButton it stays pressed until it is pressed again. So we use code to unpress it.
order.add(btn4);
});
ToggleButton btn3 = new ToggleButton();
btn3.setText("btn3'");
btn3.setOnAction(actionEvent ->
{
btn3.setSelected(false);//When you selected a ToggleButton it stays pressed until it is pressed again. So we use code to unpress it.
order.add(btn3);
});
ToggleButton btn2 = new ToggleButton();
btn2.setText("btn2");
btn2.setOnAction(actionEvent ->
{
btn2.setSelected(false);//When you selected a ToggleButton it stays pressed until it is pressed again. So we use code to unpress it.
order.add(btn2);
});
ToggleButton btn1 = new ToggleButton();
btn1.setText("btn1");
btn1.setOnAction(actionEvent ->
{
btn1.setSelected(false);//When you selected a ToggleButton it stays pressed until it is pressed again. So we use code to unpress it.
order.add(btn1);
});
Button btnPlay = new Button("play");
btnPlay.setOnAction(actionEvent ->
{
List<Timeline> timeLines = new ArrayList();//This List will hold the TimeLines so that it can be used later to play the animation in order.
for (ToggleButton tempToggleButton : order)//Create a press animation and a release animation for each ToggleButton in the List order
{
KeyFrame pressButton = new KeyFrame(Duration.seconds(1),
(kfActionEvent) ->
{
System.out.println(tempToggleButton.getText() + "Selected!");
tempToggleButton.setSelected(true);
});
Timeline pressTimeline = new Timeline();
pressTimeline.getKeyFrames().addAll(pressButton);

SequentialTransition sequentialTransition = new SequentialTransition();
sequentialTransition.getChildren().addAll(timeLines);//Add all the Timelines created to a SequentialTransition
sequentialTransition.play();
sequentialTransition.setOnFinished(stActionEvent -> {
timeLines.clear();//Once done, clear the animations
});
});
VBox root = new VBox();
root.getChildren().addAll(btn1, btn2, btn3, btn4, btnPlay);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
