Fixed (not tested)

pawn Код:

CMD:drag(playerid, params[])
{
       SetPlayerPos(playerid,drag coords);
       SetPlayerVirtualWorld(playerid,0);
       else 
       if(IsPlayerInAnyVehicle(playerid);
       SetPlayerVehiclePos(playerid,drag coords inside a vehicle);
       SetPlayerVirtualWorld(playerid,0);
       return 1;
// To take the coords go to your drag map location and do /save in the player/vehicle spawn
}

I removed some useless stuff(they had no effect(useless lines))
Let me tell you your mistakes:
First you've placed no player/vehicle coords
Second you were teleporting the player to VirtualWorld3(your random thing)
Third your code was wrong.
Fourth i fixed your code just add your player and vehicle pos
