Hi! I'm making an applet to simulate Brownian motion, which works just fine.
However, I have this problem with adding an extra feature. The main class
looks like this:

Code:

public class BrownAnimation extends Applet implements MouseListener{

    boolean clicked=false;
    int xborder=400;
    int yborder=400;
    int x;
    int y;

    Model m;
    View v;
    Simulation sim;
    Manipulation manic;

    public void init(){
        addMouseListener(this);

        /*      m=new Model(200,200,xborder,yborder);
        v=new View(m);
        sim=new Simulation(m,v);
        manic=new Manipulation(m);

        add(v);
        add(manic); */
    }

    public void mouseClicked(MouseEvent e) {

        if(clicked==false) {
            x=e.getX();
            y=e.getY();

            m=new Model(x,y,xborder,yborder);
            v=new View(m);
            sim=new Simulation(m,v);
            manic=new Manipulation(m);

            add(v);
            add(manic);
            clicked=true;
        }
    }

}

Model keeps track of individual particles, and makes them move.
View draws up the graphical components.
Manipulation is a set of buttons to manipulate particle velocity.
Simulation clocks it all.

The Model constructor takes four parameters: the coordinates for the particle
"ground zero", and the limits of the "beaker". If a particle hits the beaker wall,
it will stop.

This all works just fine using the code segment I've commented away.
However, I tried to add an extra feature with the mouseListenet:
The ability to choose a "ground zero" by clicking. Now, the applet
displays nothing, although it loads, and reacts to clicking
(I let it print out a line to the terminal when clicked).

Could you please help me solve this problem?
This is a school project, and they're not helping me.....
