for some reason this if statement never executes even if all arrays are true.let me know if you need more code

if statement problem
[sup]How is the array declared? Is it passed around to multiple classes? I once had a problem that was caused by actually having 2 versions of the array kicking around. Also how do you knwo that the statements are actually true, did you look at the array with a debugger?[/sup]
[sup]Just a side note the brackets around your array access are just taking up space.[/sup]

1. It's easier to just use the value, rather than comparing to true (do you say "is it true that we have stopped?" or "have we stopped?" - albeit the names aren't quite so nice in this case)
2. Place a breakpoint on the if, run with debugging enabled and inspect the values of board[0,0] etc.

here is some more code for clarification of my problem.

That's because your 2nd statement can never be true if the fisrt one is;
[font=Consolas][size=2][color=#0000ff][font=Consolas][size=2][color=#0000ff][font=Consolas][size=2][color=#0000ff]if[/font][/font][/font][font=Consolas][size=2][font=Consolas][size=2] (pX >= 10 && pX <= 20 [/font][/font]...

From the sounds of it I think you might be looking for an OR statement not an AND statement, if that is the case than change it to this;
[font=Consolas][size=2][color=#0000ff][font=Consolas][size=2][color=#0000ff][font=Consolas][size=2][color=#0000ff]if[/font][/font][/font][font=Consolas][size=2][font=Consolas][size=2] (board[0]==1 || board[1]==1 || board[2]==1)[/font][/font]
Also using the & operator forces it to equate the whole statement its a binary operation, you want to use && 99% of the time instead of &.

your right,should I use a switch statement instead,
It depends what you are trying to achieve. A switch structure will not achieve anything that your if structure isn't already doing. The problem is this code;

If you change the &'s to || (OR's) than you will at least be drawing that static position you have defined (0,50,200,50). Then you can go from there.

I have tried the || operator.but it draws the line before all values in the array are filled.
Of course it does, we already stated that all of your if statements cannot be true at the same time. So again, what are you trying to achieve?
