pawn Код:

forward DoorCheck(playerid);
public DoorCheck(playerid)
{
    if(IsPlayerInRangeOfPoint(playerid, doorx, doory, doorz, 1)
    {
        SetPlayerPos(playerid, yourx, youry, yourz);
        SetPlayerFacingAngle(playerid, facingangle); // Remove if not needed :)
    }
}

And in your filterscript/gamemode set a timer to run every, uhmm, 3 seconds maybe?

pawn Код:

SetTimerEx("DoorCheck(playerid)", 3000, true, "i", playerid);

Not very efficient i know, but it gets the job done
