I think he wanted a GetClosestVehicle not IsVehicleInRangeOfPoint

so here a GetClosestVehicle function with distance parameter

pawn Код:

stock GetClosestVehicle(playerid, &Float:dis = (Float:0x7F800000))
{
  dis = (Float:0x7F800000);
  new Float:X, Float:Y, Float:Z;
  if(GetPlayerPos(playerid, X, Y, Z)) {
    new vehicleid = INVALID_VEHICLE_ID;
    for(new v, Float:temp, Float:VX, Float:VY, Float:VZ; v != MAX_VEHICLES; v++) {
      if(GetVehiclePos(v, VX, VY, VZ)) {
        VX -= X, VY -= Y, VZ -= Z;
        temp = VX * VX + VY * VY + VZ * VZ;
        if(temp < dis) dis = temp, vehicleid = v;
      }
    }
    dis = floatpower(dis, 0.5);
    return vehicleid;
  }
  return INVALID_VEHICLE_ID;
}

and the usage

pawn Код:

new closest_vehicle = GetClosestVehicle(playerid);

pawn Код:

//with distance
new closest_vehicle, Float:distance;
closest_vehicle = GetClosestVehicle(playerid, distance);
