Simple example using dcmd and sscanf, a great combination for making commands

pawn Код:

dcmd_heal(playerid,params[])
{
  if(sscanf(params,"i",strval(params))) SendClientMessage(playerid,red,"Usage: /heal <playerid>");
  else
  {
    if(!IsPlayerConnected(strval(params))) return SendClientMessage(playerid,red,"Error, player not found!");
    SetPlayerHealth(strval(params),100);
    format(string,sizeof(string),"You have been healed by %s",PlayerName(strval(params)));
    SendClientMessage(strval(params),red,string);
  }
  return 1;
}

Hope that helps.

Note, you will need to define certain things to make this work with your script, this is merely an example to get you started
