Hello there.
I'm wondering how can I switch 2 type of values with sscanf. What I mean?
Example, a player have to type the ID of a vehicle OR the plate of the vehicle.
So.. how can I make it?

PHP код:

CMD:rplate(playerid, params[])
{
    if(!GetPlayerVehicleID(playerid)) return SCM(playerid, RED, "You must be in a vehicle.");
    
    new 
        target,
        plate[12+EOS] = EOS;
    if(sscanf(params, "I(65535)S()[12]", target, plate)) 
        return SCM(playerid, LBLUE, "/rplate [blabla]");
    if(target == INVALID_VEHICLE_ID && strval(plate) < 2)
        return SCM(playerid, RED, "Error"); 


If I type nothing after /rplate, I've "Error" message. If I type an ID, this working too but if I type a plate I've "/rplate" message. I think because I is optionnal but I can't pass it.
So, I hope you understand what I mean.
Thanks you'!
