Easy. Use a timer.

Example:

pawn Код:

//After the includes
forward FreezeTimer(playerid);

//When they teleport
TogglePlayerControllable(playerid,0);
SetTimerEx("FreezeTimer",3000,0,"d",playerid);

//When The Timer Stops
public FreezeTimer(playerid)
{
  TogglePlayerControllable(playerid,1);
  return 1;
}
