bullet direction

I need some help with bullets....
When I shoot, the bullets go fine, but when i hit another key the bullets go the other way

Maybe i didn't say enough... When i press the left key the direction is 0. So when I shoot the bullets go left. But when i hit the right button the bullets stop going to the left and then go right. Im not really looking for code, i want to know how to do it.

I notice that you've got a direction field for your bullets, but that you don't use it. Instead, you're using a local direction variable only. (That's kind of confusing to have to direction variables.)

So my suggestions are:
a) When you create the bullet, set its direction according to the arrow key that is pressed (b.bullet\direction = direction)
b) When you draw the bullets, make sure you reference "if b\direction...", not just "if direction...".
