Hmm, why don't you let him enter and remove him then?

Like, he is entering a mod shop and the callback is called

pawn Code:

public OnEnterExitModShop(playerid, enterexit, interiorid)
{
    if(enterexit == 1) // If enterexit is 1, this means they are entering
    {
        SetVehiclePos(GetPlayerVehicleID(playerid), X, Y, Z); // Change the coordinates
        SetPlayerInterior(playerid, 0); // Back to the normal interior
    }
    return 1;
}
