[Scenario]

You will need to do some editing:

pawn Код:

forward NearByMessage(playerid, color, string[]);
public NearByMessage(playerid, color, string[])
{
    new Float: PlayerX, Float: PlayerY, Float: PlayerZ;
    foreach(Player, i)
    {
        GetPlayerPos(playerid, PlayerX, PlayerY, PlayerZ);
        if(IsPlayerInRangeOfPoint(i, 12, PlayerX, PlayerY, PlayerZ))
        {
            if(GetPlayerVirtualWorld(playerid) == GetPlayerVirtualWorld(i) && GetPlayerInterior(playerid) == GetPlayerInterior(i))
            {
                SendClientMessage(i, color, string);
            }
        }
    }
    return 1;
}
