i've done the layout but i just can't figure out the events for each button.
the lecturer is no help.
this is the assignment page
http://194.81.104.27/~gary/csy1020/20052006/csy1020Ass2.pdf
i need to make the buttons in the grid to form a letter M shape by using forward button and Rotate button.
this is my code so far and i haven't got much time left. i'm sorry if the code is messy but it works so far...
thank you

hi ,
i'm so sorry but its not how its meant to be done my friend..
its meant to appear as a m shape when clicking forward button and rotate button.
the forward button makes buttons on the grid turn black one after another like a robot movement going north, then the rotate button makes buttons on the grid turn black going south east direction then changes to north east direction. then the last part is south direction with the forward button. the direction textfield has to stat the direction you need to go when click forward and rotate like this N,NE,E. the same for square textfield but this stats the number square your on when your clicking forward button and rotate.
it has to form as you see it on my assigment click after click.
i've changed my code to 1 dimentional array because i was told i'm doing it wrong and slightly harder by doing 2 dimentional array. where i have set the start postion is where the the movement needs to start which needs to go north first.
thanks you for the help before hand but i'm really stuck and i have nowhere else to turn to.
i hope this code is ok:

thank you
you make it look easy.
there's statments that you done i just need a understanding what the code suppose to do at that point.
if you know any websites regarding this that would be cool instead of you explaining.
you stated:
private boolean isInBounds(int x, int y)
{
if(x < 0 || x > b[0].length-1 || y < 0 || y > b.length-1)
return false;
return true;
} ?
setDirection(-1, 0); ?
GridBagConstraints gbc = new GridBagConstraints();
gbc.insets = new Insets(8,15,0,15);
gbc.weightx = 1.0;
gbc.fill = GridBagConstraints.HORIZONTAL;
gbc.gridwidth = GridBagConstraints.REMAINDER; ??
private void forward()
{
currentPosition[0] += direction[0];
currentPosition[1] += direction[1];
int row = currentPosition[0];
int col = currentPosition[1];
//System.out.println("row = " + row + "\tcol = " + col);
if(isInBounds(row, col))
b[row][col].setBackground(Color.black);
String loc = String.valueOf(row) + ", " + col;
squareField.setText(loc);
} ???
thank you very much...
