He means:

pawn Код:

new pHoldingKeyFire[ MAX_PLAYERS ];

public OnPlayerKeyState...
{
    if(PRESSED(KEY_FIRE))
        pHoldingKeyFire[playerid] = 1;
    if(RELEASED(KEY_FIRE))
        pHoldingKeyFire[playerid] = 0;
    return 1;
}

When you want to check if a player is holding KEY_FIRE, just use

pawn Код:

if(pHoldingKeyFire[playerid])
{
    //Do something
}
