Using Cursor Keys

Does Proce55ing know when cursor keys are pressed? What are the constants for <UP>, <LEFT>, <RIGHT>, <DOWN> keys?

something like this should work:
Code:public void keyPressed(KeyEvent e) {
switch (e.getKeyCode()) {
case KeyEvent.VK_UP:
// do something
break;
case KeyEvent.VK_UP:
// do something
break;
case KeyEvent.VK_UP:
// do something
break;
case KeyEvent.VK_UP:
// do something
break;
}
} |

in this case you're switching into regular java.. you don't have to use 'switch' by any means, but it's often cleaner (and faster, and better coding practice) than a whole mess of 'if' statements.
