I think this sscanf plugin will work for you. Click me

use sscanf like this:

pawn Код:

YCMD:spec(playerid, params[], help)
{
    #pragma unused help 
// Keep pragma unused help if you don't want to use the help thing y_commands have (or delete it if you do)
    new id; // The ID you will enter after /spec
    if(sscanf(params,"u",id)) SendClientMessage(playerid, -1, "Usage: /spec [id/name]");
    else if(id == INVALID_PLAYER_ID) SendClientMessage(playerid, 0xFF0000FF, "Player is not connected.");
    else
    {
        // Do what you want here.
    }
    return 1;
}
