warhammer 40k game(some bartender please move this to game forum)

[Frank McDeffer]

hi, im making a very simple game based on the tabletop game Warhammer 40k
this is my first java project and im starting very simple, a basic menu and a bckground with moveable images, ill add functionality later, anyways, i have read most of java head on(great book by the way) and know how to display bitmaps and a gui, but i dont know anything much beyond that, so what i want to do is when the user clicks a button on the gui, when they move their mouse onto the playing area, the selcted bitmap jumps to the mouse and follows it around the playing area till the user clicks, if anyone could give me some sample code or even just explain it to me, that would be great!

sorry about that, anyways any reply would be greatly appreciated, and if you'd like more information on the game send me a private message, however i doubt if a very good version would be available soon, unlees the community REALLY comes through for me with answers

Thanks for updating your display name!

I think this question would get more expert advice in our Swing/AWT forum. I'll move it there for you. (Follow link at the top of the page.)

There are a lot of ways to put these kind of things together.
Here's an idea to help you get started.

class Pseudo extends JPanel {
    BufferedImage image;
    // Switch this on in your button ActionListener
    // and off in this components MouseListener.
    boolean followMouse = false;
    Point loc = new Point();
 
    Pseudo(BufferedImage image) {
        this.image = image;
        addMouseListener(...);
        addMouseMotionListener(...);
    }
 
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.drawImage(image, loc.x, loc.y, this);
    }
}
 
// inside your MouseListener:
    public void mousePressed(MouseEvent e) {
        followMouse = false;
    }
 
// inside your MouseMotionListener:
    public void mouseMoved(MouseEvent e) {
        if(followMouse) {
            loc = e.getPoint();
            repaint();
        }
    }

edit: changed constructor name to properly match class name - sorry.

Have you considered creating your own cursor from the bitmap? That approach would be easier as compared to the paint efforts involved in moving the bitmap.
Do take a look at Toolkit.createCustomCursor()

[Frank McDeffer]

thanks for the replies, and the game is sort of an rts game so i dont think custom cursors would work,and thanks for moving my post marc, definitely more help here.

[Frank McDeffer]

thancks for the code craig, but im a little confused on how to implement it, heres the code i have so far,its just some very simple code for a gui and two images:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
 
  
public class ColorWheel {
    JFrame frame;
JPanel panel;
IPanel IP;
    public static void main(String[] args) {
        ColorWheel gui = new ColorWheel();
        gui.go();
    }
    public void go() {
        JButton Mbutton = new JButton("Move");
        JButton Fbutton = new JButton("Fire");
        panel = new JPanel();
        Mbutton.addActionListener(new ColorListener());              
        MyDrawPanel drawpanel = new MyDrawPanel();
        IP = new IPanel();        
        frame = new JFrame();
        frame.setTitle("WARHAMMER 40K v0.0001");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Mbutton.setSize(90,500);
panel.setLayout(new BoxLayout(panel,BoxLayout.X_AXIS));
panel.add(Mbutton);
panel.add(Fbutton);
panel.setBackground(Color.darkGray);
frame.getContentPane().add(BorderLayout.SOUTH,panel);
drawpanel.setSize(90,700);
frame.getContentPane().add(BorderLayout.CENTER,IP);
frame.getContentPane().add(BorderLayout.EAST,drawpanel);
frame.setSize(700, 700);
frame.setVisible(true);     
 
    }
    class ColorListener implements ActionListener {
        public void actionPerformed(ActionEvent event) {
    frame.repaint();
    }
    }
}    
class IPanel extends JPanel {
public void paintComponent(Graphics IG) {
Image img = new ImageIcon("C:/Documents and Settings/Austen/My Documents/My Pictures/Ethereal.png").getImage();
Image img2 = new ImageIcon("C:/Documents and Settings/Austen/My Documents/My Pictures/Tau_XV8_Battlesuit.png").getImage();
IG.drawImage(img,0,0,this);
IG.drawImage(img2,50,50,this);
}



}

Thank you so much, you're a genious! it works just like i wanted. now i just need to figure out how to make it so that you can select which image you want to move!(also, if i could use this to choose who should shoot that would be great)
