This makes no sense for this, since it not a real system to detect where the player marked the map, just a little trick for it..

For the GPS thing you could do (I will do a complete example for it tomorrow):

Код:

//Top of the script:

new GPSx[MAX_PLAYERS];
new GPSy[MAX_PLAYERS];
new GPSz[MAX_PLAYERS];
new bool:GPSon[MAX_PLAYERS];

//command /gps:

SetPlayerMarkingMap(playerid,1);

// In the callback:

if(MarkID == 1)
{
GPSx[playerid] = X;
GPSy[playerid] = Y;
GPSz[playerid] = Z; // Not really needed...
GPSon[playerid] = true;
}

// Then create a timer which checks the distance etc.... and turns off if the destination is reached

I think you didn't really understand the sense for this...

GetPlayerMarkedPlace could be done, but isn't really needed because of the callback.
