I'm trying to make a carshop/dealer, i want so that if you do /prices you get a list of the availble cars from that carshop in the chatbox.
When you do /buy you got a menu with the kind vehicle like, bikes, normal cars, sport cars. But how to make that command so that it only can be used at a zone ( this is what i have for the coordinates etc:

Код:

// Above OnGameModeInit:
new carshop;


public OnGameModeInit() 
{
  carshop = GangZoneCreate(-2000,689, 262,6848, -1915,71, 329,7492);
  return 1;
}


public OnPlayerSpawn(playerid) 
{
  GangZoneShowForPlayer(playerid, carshop, 0x00000096);
  return 1;
}
