Your basic command

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    if(strcmp(cmdtext, "/myroom", true, 10) == 0)
    {
        SetPlayerPos(playerid, 1638.0869,-1145.4698,23.9063);
        SendClientMessage(playerid, 0x00FF00AA, "You have teleported to /MyRoom.");
        return 1;
    }
    return 1;
}

is working fine with me.

JUST ADD:

pawn Код:

SetPlayerInterior(playerid,0);
        SetPlayerFacingAngle(playerid,0.0);
