Try to use pickups instead of /enter /exit commands.

If you don't understand tutorial, but you understand Creating pickups from samp wiki:

pawn Код:

new pickup;
public OnGameModeInit()
{
       pickup = CreatePickup(model(I recommend you ID 1239), type(I put types in description), X cordinates, Z cordinates, Y cordinates, choose virtual world(if you want that pickup in all worlds set this to "-1");
       return 1;
}
public OnPlayerPickUpPickup(playerid, pickupid)
{
       if(pickupid == pickup)
       {
               SetPlayerPos(playerid, X, Y, Z);
               SetPlayerInterior(playerid, (interiorid that you want));
       }
}

Note: if you use something like this pawn code you need to create pickup for exit too, so that pickup need to contain diffrent pickup id and other things.
I hope you understant that now and if you alredy know it then sorry.
If it helped rep++?
