I'm not pretty sure, but you can try this :

PHP код:

public OnGameModeInit()
{
    SetTimer("CheckInterior",3000,1);
    return 1;
}
forward CheckInterior(playerid);
public CheckInterior(playerid)
{
        new string[128];
        format(string, sizeof(string), "You are in : %i", GetPlayerInterior(playerid)); 
        GameTextForPlayer(playerid, string, 3000, 5);
}
