I accidentally typed .getScene(scene); instead of .setScene(scene); and it took me 10 minutes to fix it.
Am I doomed at coding?

[@desmondkuffour397]

@@catharperfect7036 you're doomed if you stop.

[@saimhafeez4240]

what about going back to scene 1 without making new scene ?

[@aldolunabueno2634]

This is a good question, because sometimes we want to our software to be less resource-intensive. This is my approach:
public class SceneController {
static private Stage stage;
static private Scene scene1;
static private Scene scene2;
@FXML
private void switchToScene1(ActionEvent event) {
stage.setScene(scene1);
stage.show();
System.out.println("Stage: " + stage);
System.out.println("Scene 1: " + scene1);
}
@FXML
private void switchToScene2(ActionEvent event) throws IOException {
if (scene2 == null) {
Parent root = FXMLLoader.load(this.getClass().getResource("scene2.fxml"));
scene2 = new Scene(root);
scene1 = ((Node)event.getSource()).getScene();
stage = (Stage) scene1.getWindow();
}
stage.setScene(scene2);
stage.show();
System.out.println("Stage: " + stage);
System.out.println("Scene 2: " + scene2);
}
}

[@lenaandthelambcampingadven3422]

So this is how one should create a modular Ui? Scenes are a collection of linked Ui elements

[@kaisander5672]

Its a great tutorial and all but theres a lot of stuff that i don't understand that wasn't explained... Especially the five lines of code that are in the methods for switching scene. I would've liked it a lot more if there was a bit more explanation as to why you wrote the lines that you did. thanks

[@andrijakolenda8161]

Really appreciate the video, even though scene builder isn't popular content. Helped me a ton brother!

[@JLSXMK8]

You literally uploaded this just in time!!! I was wondering how I could switch scenes in JavaFX, because I'll need to work on a project coming up. Let me tell you, if the stuff in this video works on my PC, you've just saved the entire thing for me! Thank you!

[@CHITUS]

Love this video. I was wondering how to do this switching the scenes, now thanks to you I'm enlightened:)

[@learntoswim512]

Any reason why you don't need to add @FXML before the switchToScene1 and 2 function? I had to to make it work. Thanks.

[@nisarshaikh-e6o]

i like your video,i am learing javafx from you

[@johnmcafee9169]

this course is really helpful

[@ernanfer2]

I like all your videos about javaFx ...thanks for share

[@peterg.1821]

I appreciate your video! It provided me with significant assistance. Greetings from Vienna!

[@selekt7]

Ehi, I updated some line and extended this to other two classes and it worked:
public abstract class SceneController {
private Stage stage;
private Scene scene;
private FXMLLoader fxmlLoader;
public void goToGame(ActionEvent event) throws IOException {
fxmlLoader = new FXMLLoader(Application.class.getResource("scene1.fxml"));
stage = (Stage) ((Node) event.getSource()).getScene().getWindow();
scene = new Scene(fxmlLoader.load());
stage.setScene(scene);
stage.show();
}
public void goToMenu(ActionEvent event) throws IOException {
fxmlLoader = new FXMLLoader(Application.class.getResource("scene2.fxml"));
stage = (Stage) ((Node) event.getSource()).getScene().getWindow();
scene = new Scene(fxmlLoader.load());
stage.setScene(scene);
stage.show();
}
}
public class MenuController extends SceneController {
@Override
public void goToGame(ActionEvent event) throws IOException {
super.goToGame(event);
}
}

[@Kennerdoll]

3:08 - I'm kindly asking if you could explain what you mean by "CASTING" in the context you are using it.

[@anandbmuley]

Thank You @Bro Code. Finally I found a simple solution. Thank for sharing this video :)

[@ctluwua7695]

Parent root = new FXMLLODER.BLA BLA bla bla bla bla bla bla bla 😂😂😂😂😂😂😂

[@misharatkevich9808]

HOLY FUCKING SHIT, the scene/screen switch is EXACTLY the problem that stumped me earlier on my first serious project, so much so that it really killed my motivation at that time, and everything I could find on the subject was something monstrously complicated and big that I couldn't adapt and make work.
I'll need to test this myself, of course, but... this looks so concise. This looks REALLY concise. I still have the question of "can this work if each of the two methods is in its own separate controller?" (so that you don't have to have the same controller for all the scenes). but other than that... this is so concise. And the only complex part that I'm not fully understanding yet is the Stage/Node/event cast, which is a lot of casting and chaining and I'll need to read the docs more carefully to see how and why this works, but if this works out for me... holy shit, this is what I needed. I think this is what I needed.
Thanks a lot, man.
EDIT: Update, did it slightly differently (with some other help), but in a similar way. I'm not sure if this is the best option, but this helped A LOT. Thank you.

[@hunchortw]

do you mind helping me out by saying what way you did it? because i can't get the scenes to swtich, it gives me pointer null error.

[@StarDust4866]

@@hunchortw Not sure you'll see this but what solved it for me was putting the fxml files in the resources file. No problems after that.

[@carolinezeiler8112]

You just saved the day (23:25). Been working on this all afternoon, my head is going to explode. Been looking in all my books, been watching all my usual tutorials and some others, your code is the only one that actually worked. THANKS ++++ I learned that you do not have access to the Controller Panel on the bottom left part of the SceneBuilder when you open it in IntelliJ. You can only access it within SceneBuilder itself.

[@oussamajmaa9205]

thank you so much it works perfectly , but can i send data from scenes using this method ?

[@alp4125]

Why are we pass a ActionEvent reference to function parameter?We did do this too in the 6th video of in your JAVAfx playlist like that we use that here?Nonethless we are don't use a ActionEvent ,Why do we define ActionEvent?Please clarify my question anybody:)

[@infern0824]

Can anyone PLEASE tell how can we do this: I have a log in page including a username button, if the user enters the admin’s name the log in button switches to the admin scene, and if the user enters another name, the log in button would take it to another scene?

[@techhub_]

Amazing, you made things so easy!

[@MaryamPrhn]

great!!

[@gamingman0082]

SOMEONE PLEASE HELP ! When i am in JAVA FX Scene Builder and i click On Action in the Code settings of the button, the two options of "Switch to scene" doesn't pop up. The code in Java is written very good, i also copy-pasted it from the description. What can be wrong? Please help

[@jitsevanparys1337]

Quick question, I got the error 'Caused by: javafx.fxml.LoadException: Root hasn't been set. Use method setRoot() before load.' Do you know how I can fix this?

[@huzaifaalam8358]

[@kaneshirosora1707]

how the sceneController class is connected to main method ? from what i saw is we didnt inherit or declare any method from sceneController class into the main method. or is it because of the Scene1.fxml file connected to the sceneController class ?

[@onfued3088]

the Scene1.fxml file connected to the sceneController class

Another comment because you're saving my university life

[@SylphietteGreyrat-p9d]

Hello BRO , What if the switch of scene doesn't trigger with an event. I'm trying to change a scene with a countdown timer. Any thoughts? My code is below:
int i = 20;
@Override
public void initialize(URL url, ResourceBundle resourceBundle){

text.setText(String.valueOf(i));
Timeline timeline = new Timeline(new KeyFrame(Duration.seconds(1),e ->{
i--;
text.setText(String.valueOf(i));
if(text.getText().equalsIgnoreCase("0")) {
System.out.print("GG");
nextQuestionArrow.setVisible(true);
textFieldAnswer.setEditable(false);
text.setVisible(false);


Parent root = FXMLLoader.load(getClass().getResource("Scene13BRoomAndPillarQuestion2.fxml"));
stage = (Stage)((Node)event.getSource()).getScene().getWindow();


scene = new Scene(root);
stage.setScene(scene);
stage.show();

root = null;
stage = null;
scene = null;

}
}));
}

[@sushantlama9010]

Searched everywhere but couldn't find , but here it was hidden.

[@lorenzogradaschi3711]

is this also showing the stage in the same window or not? or is creating another window?

[@fidam1483]

Which version sdk do you use and you use maven or gradle

[@maealcantara5147]

Does the other scene closes when it switches to another scene?

[@alesto8962]

Im back to this video with additional question. Bro how to measure the time between switching scenes in mili or nanoseconds? I know for this example it is nearly 0 but for more complicated memory-eating scenes?
