Button in borderlayout
I'm new to java and are working on my first big projekt which is a game. In this tower defence game I want a couple of menues, to both display information and have bottuns. To make this i'm using BorderLayout(), but I can't figure out how to use it proberly. Here are my code:
Main class:
public class VectorTD{ public static void main(String[] args) { // Creates the display GameFrame frame = new GameFrame(); } }
GameFrame class that draws everthing:
/pakke der styrer farver import java.awt.Color; import javax.swing.*; //Pakke der hjælper med at lave vinduet import javax.swing.JFrame; import java.awt.*; public class GameFrame extends JFrame { static final int SCREEN_WIDTH = 1000; static final int SCREEN_HEIGHT = 1000; GameFrame() { this.setLayout(new BorderLayout()); //the bottun this.add(new Menu(), BorderLayout.NORTH); //the game this.add(new GamePanel(), BorderLayout.CENTER); pack(); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setSize(SCREEN_WIDTH, SCREEN_HEIGHT); this.setBackground(Color.BLACK); setVisible(true); setResizable(false); } }
Class that should make the bottun
import java.awt.*; import javax.swing.*; import java.awt.Graphics; import javax.swing.JButton; public class Menu extends JPanel{ Menu() { JButton b=new JButton("Click Here"); b.setBounds(50,100,95,30); this.add(b); } private void makeTopMenu() { } }
GamePanel class:
import java.awt.*; import javax.swing.*; import java.awt.Graphics; public class GamePanel extends JPanel implements Runnable { static Graphics graphics; final static int FPS = 100; final static public long SKIP_TICKS = 1000000000 / FPS; static public int lives = 25; static public int money = 100; static public boolean roundStart = false; GamePanel() { new Thread(this).start(); Square.makeGrid(); Vectoid.makeVectoids(); } public void paint(Graphics g) { Image image = createImage(GameFrame.SCREEN_WIDTH, GameFrame.SCREEN_HEIGHT); graphics = image.getGraphics(); draw(graphics); g.drawImage(image, 0, 0, this); } public void draw(Graphics g) { Square.drawGrid(g); if (roundStart==true){ for (int i = 0; i < Vectoid.currentNumberOfVectoids; i++) { if (Vectoid.listOfVectoids[i].dead == false) { Vectoid.listOfVectoids[i].draw(g); Vectoid.listOfVectoids[i].move(); } } } Toolkit.getDefaultToolkit().sync(); } // Gameloop public void run() { // long then = System.nanoTime(); // The gameloop runs until the program is closed while (true) { // Saves the current time long now = System.nanoTime(); repaint(); // After the game has been updated, the program needs to wait until next // gameupdate. This waiting time is determined by the FPS variable. long sleeptime = SKIP_TICKS - (System.nanoTime() - now); if (sleeptime >= 0) { try { Thread.sleep(sleeptime / 1000000); } catch (Exception e) { System.out.println("Error: Can't sleep."); } } // If sleeptime < 0, the program is not updated fast enough else { System.out.println("We are running behind"); } } } }
