我正在使用Scene Builder界面并通过fxml doc将其链接到Eclipse中。我的游戏背景和网格窗格/按钮显示正常。 但是如何让按钮工作？ 我花了几天时间研究这个，虽然我确信这很简单！ 基本上，我想要它做的就是当我点击按钮时显示数字1。我的游戏引擎本身工作正常，数字显示在TEXT UI的网格上。 这只是我的GUI。
public class MyController {
private Maze game = new Maze();
private Label messages = new Label();
// private int moves = 0;
public void handleStart(ActionEvent event) {
System.out.println("Welcome to The Maze.You must find all"
+ "+ the squares with zeros in them to make it out of the maze.");
}
public void handleHelp(ActionEvent event) {
System.out.println("click on the ?, if you click on a square that is not 'zero'"
+ " you die. To win you must click on all the squares that are 'zero'. Good Luck! ");
}
@FXML
public void handleClick(ActionEvent event) {
Button c = (Button) event.getSource();
String id = c.getId();
int row = Integer.parseInt(id.substring(6, 7));
int col = Integer.parseInt(id.substring(7, 8));
System.out.println("click: + " + event + "row=" + row + "," + col);
boolean good = this.game.move1(row, col);
if (good) {
this.messages.setText("Good move");
} else {
this.messages.setText("Bad move. Try again...");
}
updateView();
}
@FXML
GridPane grid;
public void updateView() {
for (int row = 0; row < 3; row++) {
for (int col = 0; col < 6; col++) {
String bid = "#button" + row + col;
Button b = (Button) grid.lookup(bid);
System.out.println("Found Button: " + b);
// Cell cell = game.getCell(row, col);
// c.setText("" + cell.getValue());
}
}
}
} 以下是我的GUI类：
public class GUI extends Application {
private Maze game = new Maze();
private int moves = 0;
@Override // Override start method in Application Class
public void start(Stage primaryStage) throws IOException {
Parent root =FXMLLoader.load(getClass().getResource("themaze.fxml.fxml"));
Scene scene = new Scene(root, 788, 522 );
primaryStage.setResizable(false);
primaryStage.setTitle("The Maze");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
Application.launch(args);
}
