You need sscanf to do this or isnull() from ZCMD
anyways i made a quick one for ya

pawn Код:

CMD:me(playerid,params[])
{
    new Message[128];
    if(isnull(params)) return SendClientMessage(playerid,white,"USAGE:/me <text>");
    if(sscanf(params,"s[128",Message)) return SendClientMessage(playerid,white,"USAGE:/me <text>");
    return 1;
}
