Thread: Help with ImageIcon

  1. #1

    Unhappy [SOLVED] Help with ImageIcon

    My background for my game isn't displaying at all. I use a mac, do I have to do something different? Heres my Panel class:
    package net.nivangerow.umadbro;
    import java.awt.*;
    import java.awt.event.*;
     
    import javax.swing.*;
     
    public class Panel extends JPanel implements ActionListener{
    	public Player p;
    	Image img;
    	Timer time;
    	public Panel()
    	{
    		p = new Player();
    		addKeyListener(new AL());
    		setFocusable(true);
    		ImageIcon i = new ImageIcon("/background.png");
    		img = i.getImage();
    		time = new Timer(5, this);
    		time.start();]
    	}
    	public void actionPerformed(ActionEvent e)
    	{
    		p.move();
    		repaint();
    	}
    	public void paint(Graphics g)
    	{
    		super.paint(g);
    		Graphics2D g2d = (Graphics2D) g;
    		g2d.drawImage(img, 0, 0, null);
    		g2d.drawImage(p.getImage(), p.getX(), p.getY(), null);
    	}
    	private class AL extends KeyAdapter
    	{
    		public void keyReleased(KeyEvent e)
    		{
    			p.keyReleased(e);
    		}
    		public void keyPressed(KeyEvent e)
    		{
    			p.keyPressed(e);
    		}
    	}
    }
    At the moment my images are in the same folder as the .java files, and I use eclipse.

    Because you bumped your thread, it will now show that this thread has received replies, and most people will assume you're already getting help so they won't bother looking at it. Plus it's only been a few minutes- a little patience goes a long way!

    Can you access that file at all? Print out the full path- is it what you expected?

    I'm not sure, can you? What happened when you tried to access it and print out the full path? What happens when you use the full path for the ImageIcon?

    You're skipping over most of my questions. Saying that it doesn't display doesn't really help- when you create a File at that location, what is the full path of that File? What happens if you get rid of the leading /? Are you sure you're using the correct path separator character for your system?

    Here is the full filepath and it still doesnt display:
    /Users/nivangerow/Documents/workspace/U MAD BRO/src/net/nivangerow/umadbro/background.png

    Also there is an error if i use any escape characters. Nothing changes when I get rid of the leading /. I am sure that I use the correct path separator character for my system.

    Here are my specs:
    MacBook 13-inch, Mid 2010, Processor: 2.4 GHz Intel Core 2 Duo, Memory: 2 GB 1067 MHz DDR3, Graphics: NVIDIA GeForce 320M 256 MB, Software (OS): Mac OS X Lion 10.7.1 (11B26)

    Again, a little patience goes a long way. That's definitely one way to make sure people don't want to help you. I'm not going to help you if you do it again- there are hundreds of posts here, each with its own urgent user waiting on a response, and their time is just as important as yours. And the volunteers helping here do it for free, most of the time on their lunch break or between classes. You've been told about it twice now- you won't be told a third time.

    Have you tried refreshing your eclipse project?

    What if you take eclipse out of the equation entirely?

    Create a class that reads a file next to it. Go from there. (that's what I was hinting you do in my first response, btw, Mr. Impatient Pants)

    I have tried this: (its slightly edited)
    package net.nivangerow.umadbro;
    import java.awt.*;
    import java.awt.event.*;
     
    import javax.swing.*;
     
    public class Panel extends JPanel implements ActionListener{
    	public Player p;
    	Image img;
    	Timer time;
    	public Panel()
    	{
    		p = new Player();
    		addKeyListener(new AL());
    		setFocusable(true);
    		ImageIcon i = new ImageIcon(getClass().getResource("background.png"));
    		System.out.println(getClass().getResource("background.png"));
    		img = i.getImage();
    		time = new Timer(5, this);
    		time.start();
    	}
    	public void actionPerformed(ActionEvent e)
    	{
    		p.move();
    		repaint();
    	}
    	public void paint(Graphics g)
    	{
    		super.paint(g);
    		Graphics2D g2d = (Graphics2D)g;
    		g2d.drawImage(img, 0, 0, null);
    		g2d.drawImage(p.getImage(), p.getX(), p.getY(), null);
    	}
    	private class AL extends KeyAdapter
    	{
    		public void keyReleased(KeyEvent e)
    		{
    			p.keyReleased(e);
    		}
    		public void keyPressed(KeyEvent e)
    		{
    			p.keyPressed(e);
    		}
    	}
    }
    Still no success....

    I have just experimented with backgrounds (Color.BLACK), etc..
    And I have set a red background to the JPanel and a green background to the frame itself. And I see green and i should actually see red. SO is my panel not being drawn or something?

    I've had problems with eclipse not keeping up with the state of the file system. And either way, it's good to eliminate possibilities.

    That code doesn't run for me because I don't have the Player class (take it out if it's not pertinent to the problem), and that code doesn't have a main method (add your GUI to a JFrame and show it). In other words, provide an SSCCE that demonstrates the problem, and we'll go from there.

    Yep, sounds like a sizing problem. What layout are you using?
