This :

pawn Код:

//on top of script
new moveobjectid;

pawn Код:

//under gamemodeinit

moveobjectid = CreateObject(..... . ...................);

then on top of script

pawn Код:

forward MoveTimer(playerid);

then
anywhere in the script just not under any callback

pawn Код:

public MoveTimer(playerid);
{
       MovePlayerObject(playerid, moveobjectid,Float:X, Float:Y, Float:Z, 10.0);//10.0 is speed in milisecs
}

then

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    if (strcmp("/mycommand", cmdtext, true, 10) == 0)
    {
        SetTimerEx("MoveTimer",timeinmiliseconds,0,"d",playerid);
        return 1;
    }
    return 0;
}
