There\'s a tiny problem that you might come across. Example:

pawn Code:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
    if (newkeys & KEY_FIRE) // 4
    {
        print("MSG 1");
    }
    if (newkeys & KEY_JUMP) // 32
    {
        print("MSG 2");
    }
    return 1;
}

If you press KEY_FIRE, it will print:

pawn Code:

MSG 1
/*
 * newkeys = 000100
 */

If you press KEY_JUMP while holding KEY_FIRE, it will print:

pawn Code:

MSG 1
MSG 2
/*
 * newkeys = 100100
 */

If you release KEY_JUMP while holding KEY_FIRE, it will print:

pawn Code:

MSG 1
/*
 * newkeys = 000100
 */

That\'s why there\'s a third parameter, which you can use to detect when a key is pressed and released (not if a key is being held down).
