Hello guys, and i want to share with you by my little script "Healing in 5 secs" xD
It's very easy:

Command:
[pawn]}
   else if ( strcmp( cmd, "!heal", true ) == 0 )
   {
      new Float:Health; GetPlayerHealth( playerid, Health );
        if ( Health >= 100 ) SendClientMessage( playerid, COLOR_YELLOW, ">> Error: You are healthy." );
      else
      {
          TogglePlayerControllable(playerid,0);
         SetTimer("Healing",5000,0);
          GameTextForPlayer(playerid, "Healing");
      }
      return 1;
      }
   return 1;
}[/pawn]

Timer:
[pawn]}
public Healing(playerid)
{
TogglePlayerControllable(playerid, 1);
SetPlayerHealth( playerid, 100.0 );
SendClientMessage( playerid, COLOR_YELLOW, ">> You have been healed!" );
}[/pawn]

Have fun!
