I am making a school project in JAVAFX and I can't figure out how to collide with my 2 objects(bullet and enemy tank). Can someone tell me the right way to do it? I am trying more than 3 weeks... google everything but still not working.

Note: this is an updatet version of the initial question.
Whats now beeing asked is how I can get access to the values of a certain row for calculations purposes. For example how can I calculate the difference betweeen values of the expensesColumn and the earningsColumn? (Because there was to much code within my questions, I deleted most of the imports)

i am customizing JavaFX TableView's header.
therefore i add a Graphic to the Label. By clicking the Label of the header i toggle my custom header(two lined). all this is working fine.
The header gets automatically resized so the custom headerfits in.
BUT, when i hide my custom headerthe headerstays large.
What am i missing so the headershrinks again?
i created a MCVE to demonstrate my problem:
public class TableViewHeaderMCVE extends Application {
private final TableView<Person> table = new TableView<>();

thanks to #James_D for his reply.
after his reply i tested the code on another computer
works on:

fails on:
JDK 1.8.0_66-b18 on Windows 7
I need a help with JavaFX. I have a program that draws lines with the mouse in the scene. When I press clear button, whole scene needs to be cleared. But only last drawn line is being cleared with this program.
When clear button is pushed, all drawn lines should be cleared. Now, only the last drawn line is being cleared.
public class Test extends Application {
private Line currentLine;
private Group root;
private ColorPicker colorPicker;
private Button clearButton;
private HBox buttons;
private Scene scene;
public void start(Stage primaryStage) {
root = new Group();
colorPicker = new ColorPicker(Color.WHITE);
clearButton = new Button("Clear");
clearButton.setOnAction(this::processActionButton);
buttons = new HBox(colorPicker, clearButton);
buttons.setSpacing(15);
root.getChildren().addAll(buttons);
scene = new Scene(root, 500, 300, Color.BLACK);
scene.setOnMousePressed(this::processMousePress);
scene.setOnMouseDragged(this::processMouseDrag);
primaryStage.setTitle("Color Lines");
primaryStage.setScene(scene);
primaryStage.show();
}
public void processMousePress(MouseEvent event) {
currentLine = new Line(event.getX(), event.getY(), event.getX(),
event.getY());
currentLine.setStroke(colorPicker.getValue());
currentLine.setStrokeWidth(3);
root.getChildren().add(currentLine);
}
public void processMouseDrag(MouseEvent event) {
currentLine.setEndX(event.getX());
currentLine.setEndY(event.getY());
}
public void processActionButton(ActionEvent event) {
root.getChildren().removeAll(currentLine);
}
public static void main(String[] args) {
launch(args);
}
}
You can have a special group for lines only:
Group groupLines = new Group();
...
root.getChildren().add(groupLines);
Add new lines into this group:
public void processMousePress(MouseEvent event) {
...
groupLines.getChildren().add(currentLine);
}
And clean only this group:
groupLines.getChildren().clear();
Here is my code, I'm trying to load a splash screen image with transparent background before my main stage starts. They come almost at the same time, but the big problem is I get a grey rectangle before anything else: .
Here is the code:
public class Menu extends Application {
private Pane splashLayout;
private Stage mainStage;
private ImageView splash;
// Creating a static root to pass to ScreenControl
private static BorderPane root = new BorderPane();
public void start(Stage splashStage) throws IOException {
final Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
this.splash = new ImageView(new Image(getClass().getResource("/splash.png").toString()));
splashStage.initStyle(StageStyle.TRANSPARENT);
showSplash(splashStage, screenSize);
// Constructing our scene using the static root
root.setCenter(new ScrollPane);
Scene scene = new Scene(root, screenSize.getWidth(), screenSize.getHeight());
showMainStage(scene);
if (splashStage.isShowing()) {
mainStage.setIconified(false);
splashStage.toFront();
FadeTransition fadeSplash = new FadeTransition(Duration.seconds(1.5), splashLayout);
fadeSplash.setDelay(Duration.seconds(3.5));
fadeSplash.setFromValue(1.0);
fadeSplash.setToValue(0.0);
fadeSplash.setOnFinished(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent actionEvent) {
splashStage.hide();
}
});
fadeSplash.play();
}
}
private void showMainStage(Scene scene) {
mainStage = new Stage(StageStyle.DECORATED);
mainStage.setTitle("book-depot");
mainStage.getIcons().add(new Image(getClass().getResourceAsStream("/icon.png")));
mainStage.setScene(scene);
mainStage.show();
}
private void showSplash(Stage splashStage, Dimension screenSize) {
splashLayout = new StackPane();
splashLayout.setStyle("-fx-background-color: transparent;");
splashLayout.getChildren().add(splash);
Scene splashScene = new Scene(splashLayout, 690, 590);
splashScene.setFill(Color.TRANSPARENT);
splashStage.setScene(splashScene);
splashStage.show();
}
public void mainGui(String[] args) {
launch(args);
}
}
Am I doing something wrong or I really can't get a transparent background?
This is what it looks like when also the other stage loads up, but I'd like it to work like that even before the main stage loads, or at least I'd want to remove the grey rectangle you can see in the other screenshot
The grey background is your "mainStage" since you are showing splash and main stages at the same time. At the beginning while showing the splash stage you can just init (not show) the main stage and show it later when the animation finishes:
public class ModifiedMenu extends Application
{
private Pane splashLayout;
private Stage mainStage;
private ImageView splash;
// Creating a static root to pass to ScreenControl
private static BorderPane root = new BorderPane();
public void start(Stage splashStage) throws IOException {
final Dimension2D screenSize = Toolkit.getDefaultToolkit().getScreenSize();
this.splash = new ImageView(new Image(getClass().getResource("/splash.png").toString()));
splashStage.initStyle(StageStyle.TRANSPARENT);
showSplash(splashStage, screenSize);
// Constructing our scene using the static root
root.setCenter(new ScrollPane());
Scene scene = new Scene(root, screenSize.getWidth(), screenSize.getHeight());
initMainStage(scene);
if (splashStage.isShowing()) {
splashStage.toFront();
FadeTransition fadeSplash = new FadeTransition(Duration.seconds(1.5), splashLayout);
fadeSplash.setDelay(Duration.seconds(3.5));
fadeSplash.setFromValue(1.0);
fadeSplash.setToValue(0.0);
fadeSplash.setOnFinished(new EventHandler<ActionEvent>() {
#Override
public void handle(ActionEvent actionEvent) {
splashStage.hide();
mainStage.show();
}
});
fadeSplash.play();
}
}
private void initMainStage(Scene scene) {
mainStage = new Stage(StageStyle.DECORATED);
mainStage.setTitle("book-depot");
mainStage.getIcons().add(new Image(getClass().getResourceAsStream("/icon.png")));
mainStage.setScene(scene);
}
private void showSplash(Stage splashStage, Dimension2D screenSize) {
splashLayout = new StackPane();
splashLayout.setStyle("-fx-background-color: transparent;");
splashLayout.getChildren().add(splash);
Scene splashScene = new Scene(splashLayout, 690, 590);
splashScene.setFill(Color.TRANSPARENT);
splashStage.setScene(splashScene);
splashStage.show();
}
public void mainGui(String[] args) {
launch(args);
}
}
I cant get this to resize, it always go for the preferred size for each screen. This is not ideal for a full screen application. It bascially just becomes a little box in the top left corner =(
I've spent days on this now but cant get it to work.
Could anyone tell me what im doing wrong? thanks
Main class:
public class Main extends Application {
public static final String MAIN_SCREEN = "main";
public static final String MAIN_SCREEN_FXML = "../gui/main.fxml";
public static final String CUSTOMER_SCREEN = "customer_main";
public static final String CUSTOMER_SCREEN_FXML = "../gui/customer_main.fxml";
#Override
public void start(Stage primaryStage) {
primaryStage.setFullScreen(true);
primaryStage.centerOnScreen();
ScreensController mainContainer = new ScreensController();
mainContainer.loadScreen(Main.MAIN_SCREEN,
Main.MAIN_SCREEN_FXML);
mainContainer.loadScreen(Main.CUSTOMER_SCREEN,
Main.CUSTOMER_SCREEN_FXML);
mainContainer.setScreen(Main.MAIN_SCREEN);
Group root = new Group();
root.getChildren().addAll(mainContainer);
Scene scene = new Scene(root);
primaryStage.setScene(scene);
primaryStage.show();
mainContainer.requestLayout();
}
public static void main(String[] args) {
launch(args);
}
First screen controller class (has FXML file):
public class MainScreenController implements ControlledScreen, Initializable{
ScreensController myController;
#FXML
private VBox mainScreen;
#FXML
private void mainScreenClicked(){
myController.setScreen(Main.CUSTOMER_SCREEN);
}
#Override
public void initialize(URL arg0, ResourceBundle arg1) {
}
#Override
public void setScreenParent(ScreensController screenParent) {
myController = screenParent;
}
Stack pane for a nice layout:
public class ScreensController extends StackPane {
public ScreensController(){
}
private HashMap<String, Node> screens = new HashMap<>();
public void addScreen(String name, Node screen) {
screens.put(name, screen);
}
public boolean loadScreen(String name, String resource) {
try {
FXMLLoader myLoader = new FXMLLoader(getClass().getResource(resource));
Parent loadScreen = (Parent) myLoader.load();
ControlledScreen myScreenControler =
((ControlledScreen) myLoader.getController());
myScreenControler.setScreenParent(this);
addScreen(name, loadScreen);
return true;
}catch(Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
return false;
}
}
public boolean setScreen(final String name) {
if(screens.get(name) != null) { //screen loaded
final DoubleProperty opacity = opacityProperty();
//Is there is more than one screen
if(!getChildren().isEmpty()){
Timeline fade = new Timeline(
new KeyFrame(Duration.ZERO,
new KeyValue(opacity,1.0)),
new KeyFrame(new Duration(1000),
new EventHandler() {
#Override
public void handle(Event t) {
//remove displayed screen
getChildren().remove(0);
//add new screen
getChildren().add(0, screens.get(name));
Timeline fadeIn = new Timeline(
new KeyFrame(Duration.ZERO,
new KeyValue(opacity, 0.0)),
new KeyFrame(new Duration(800),
new KeyValue(opacity, 1.0)));
fadeIn.play();
}
}, new KeyValue(opacity, 0.0)));
fade.play();
} else {
//no one else been displayed, then just show
setOpacity(0.0);
getChildren().add(screens.get(name));
Timeline fadeIn = new Timeline(
new KeyFrame(Duration.ZERO,
new KeyValue(opacity, 0.0)),
new KeyFrame(new Duration(2500),
new KeyValue(opacity, 1.0)));
fadeIn.play();
}
return true;
} else {
System.out.println("screen hasn't been loaded!\n");
return false;
}
}
public boolean unloadScreen(String name) {
if(screens.remove(name) == null) {
System.out.println("Screen didn't exist");
return false;
} else {
return true;
}
}
}
interface so that each screen knows its parent:
public interface ControlledScreen {
public void setScreenParent(ScreensController screenPage);
}
Second controller class to verify that the stackpane works (has FXML file):
public class CustomerMenuController implements ControlledScreen, Initializable {
ScreensController myController;
#FXML
private FlowPane customerMenuFlow;
#Override
public void initialize(URL location, ResourceBundle resources) {
for (int i = 0; i < 3;i++){
new Customer();
}
Button [] menuButtons = new Button[Customer.customers.size()];
for (int i = 0; i < Customer.customers.size();i++){
menuButtons[i] = new Button("Customer " + i);
customerMenuFlow.getChildren().add(menuButtons[i]);
}
}
#Override
public void setScreenParent(ScreensController screenParent) {
myController = screenParent;
}
}
You shouldn't use primaryStage.setFullScreen(true); for resizable applications. Not in this context anyway. Once you remove that line, the application will start with its preferred size, but then the user is able to drag the corners of the window to resize the application.
