I've got an app made in javafx and another class with menu in this project. In this menu I've got two buttons and one works (exit buuton) and I want buttonStart to open my Main class. How to launch it?
Button buttonStart = new Button("START GAME");
Button buttonExit = new Button("EXIT");
buttonExit.setOnMouseClicked(event -> System.exit(0));
My menu:
package pl.main;
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.BorderPane;
import javafx.scene.layout.HBox;
import javafx.stage.Stage;
public class Menu extends Application {
private BorderPane layout;
private Scene scene;
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage window) throws Exception {
layout = new BorderPane();
scene = new Scene(layout, 720, 480);
HBox hbox = new HBox();
hbox.setPadding(new Insets(15, 12, 15, 12));
hbox.setSpacing(10);
hbox.setStyle("-fx-background-color: #F9A825;");
Button buttonStart = new Button("START GAME");
buttonStart.setPrefSize(100, 20);
buttonStart.setStyle("-fx-background-color: #E65100;");
Button buttonExit = new Button("EXIT");
buttonExit.setPrefSize(100, 20);
buttonExit.setStyle("-fx-background-color: #E65100;");
buttonExit.setOnMouseClicked(event -> System.exit(0));
hbox.getChildren().addAll(buttonStart, buttonExit);
layout.setCenter(hbox);
window.setScene(scene);
window.show();
}
}
Class which I wanna launch:
package pl.main;
import javafx.animation.AnimationTimer;
import javafx.application.Application;
import javafx.geometry.Point2D;
import javafx.scene.Node;
import javafx.scene.Scene;
import javafx.scene.input.KeyCode;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
import java.util.ArrayList;
import java.util.HashMap;
public class Main extends Application {
private HashMap<KeyCode, Boolean> keys = new HashMap<KeyCode, Boolean>();
private ArrayList<Node> blocks = new ArrayList<Node>();
private Pane appRoot = new Pane();
private Pane gameRoot = new Pane();
private Pane uiRoot = new Pane();
private Node player;
private Point2D playerGoDown = new Point2D(0, 0);
private Point2D playerGoRight = new Point2D(0, 0);
private boolean canJump = true;
private int levelWidth;
private void initContent() {
Rectangle background = new Rectangle(720, 480);
// BackgroundFill(Color.WHITE);
levelWidth = LevelData.LEVEL1[0].length();
for (int i = 0; i < LevelData.LEVEL1.length; i++) {
String map = LevelData.LEVEL1[i] + LevelData.LEVEL2[i]+ LevelData.LEVEL1[i]+ LevelData.LEVEL2[i]+ LevelData.LEVEL1[i]+ LevelData.LEVEL2[i];
String line = map;
for (int j = 0; j < line.length(); j++) {
switch (line.charAt(j)) {
case '0':
break;
case '1':
Node block = createEntity(j * 30, i * 30, 30, 30, Color.ORANGE);
blocks.add(block);
break;
}
}
}
player = createEntity(0, 350, 40, 40, Color.YELLOW);
// a ????????????
player.translateXProperty().addListener((a, old, newValue) -> {
int offset = newValue.intValue();
//if (offset > 360 && offset < levelWidth - 360) {
gameRoot.setLayoutX(-(offset - 360));
//}
});
appRoot.getChildren().addAll(background, gameRoot, uiRoot);
}
private void update() {
if (isPressed(KeyCode.W) && player.getTranslateY() >= 0) {
jumpPlayer();
}
if (playerGoDown.getY() < 10) {
playerGoDown = playerGoDown.add(0, 1);
}
movePlayerY((int) playerGoDown.getY());
if (player.getTranslateX() <= levelWidth - 5) {
// movePlayerX(5);
movePlayerRight();
}
if (playerGoRight.getX() < 0) {
playerGoRight = playerGoRight.add(0, 1);
}
movePlayerX((int) playerGoRight.getX());
}
private void movePlayerX(int value) {
boolean movingRight = value > 0;
for (int i = 0; i < Math.abs(value); i++) {
for (Node block : blocks) {
if (player.getBoundsInParent().intersects(block.getBoundsInParent())) {
if (movingRight) {
if (player.getTranslateX() + 40 == block.getTranslateX()) {
return;
}
} else {
if (player.getTranslateX() == block.getTranslateX() + 60) {
return;
}
}
}
}
player.setTranslateX(player.getTranslateX() + (movingRight ? 1 : -1));
}
}
private void movePlayerY(int value) {
boolean movingDown = value > 0;
for (int i = 0; i < Math.abs(value); i++) {
for (Node block : blocks) {
if (player.getBoundsInParent().intersects(block.getBoundsInParent())) {
if (movingDown) {
if (player.getTranslateY() + 40 == block.getTranslateY()) {
canJump = true;
return;
}
} else {
if (player.getTranslateY() == block.getTranslateY() + 60) {
return;
}
}
}
}
player.setTranslateY(player.getTranslateY() + (movingDown ? 1 : -1));
}
}
private void jumpPlayer() {
if (canJump) {
playerGoDown = playerGoDown.add(0, -10);
canJump = false;
}
}
private void movePlayerRight() {
playerGoRight = playerGoRight.add(10, 0);
}
private Node createEntity(int x, int y, int w, int h, Color color) {
Rectangle entity = new Rectangle(w, h);
entity.setTranslateX(x);
entity.setTranslateY(y);
entity.setFill(color);
gameRoot.getChildren().add(entity);
return entity;
}
private boolean isPressed(KeyCode key) {
return keys.getOrDefault(key, false);
}
@Override
public void start(Stage primaryStage) throws Exception {
initContent();
Scene scene = new Scene(appRoot);
scene.setOnKeyPressed(event -> keys.put(event.getCode(), true));
scene.setOnKeyReleased(event -> keys.put(event.getCode(), false));
primaryStage.setTitle("Jetpack gameplay");
primaryStage.setScene(scene);
primaryStage.show();
primaryStage.setResizable(false);
AnimationTimer timer = new AnimationTimer() {
@Override
public void handle(long now) {
update();
}
};
timer.start();
}
public static void main(String[] args) {
launch(args);
}
}
In future I wanna change current Main.java into ordinary class because now I have two classes which works independently.
