OnUnoccupiedVehicleUpdate

Description​

This callback is called when a player's client updates/syncs the position of a vehicle they're not driving. This can happen outside of the vehicle or when the player is a passenger of a vehicle that has no driver.

NameDescription
vehicleidThe ID of the vehicle that's position was updated.
playeridThe ID of the player that sent a vehicle position sync update.
passenger_seatThe ID of the seat if the player is a passenger. 0=not in vehicle, 1=front passenger, 2=backleft 3=backright 4+ is for coach/bus etc. with many passenger seats.
Float:new_xThe new X coordinate of the vehicle.
Float:new_yThe new Y coordinate of the vehicle.
Float:new_zThe new Z coordinate of the vehicle.
Float:vel_xThe new X velocity of the vehicle.
Float:vel_yThe new Y velocity of the vehicle.
Float:vel_zThe new Z velocity of the vehicle.

Returns​

It is always called first in filterscripts so returning 0 there also blocks other scripts from processing it.

Examples​

public OnUnoccupiedVehicleUpdate(vehicleid, playerid, passenger_seat, Float:new_x, Float:new_y, Float:new_z, Float:vel_x, Float:vel_y, Float:vel_z)
{
    // Check if it moved far
    if (GetVehicleDistanceFromPoint(vehicleid, new_x, new_y, new_z) > 50.0)
    {
        // Reject the update
        return 0;
    }

    return 1;
}

Notes​

warning
  • This callback is called very frequently per second per unoccupied vehicle. You should refrain from implementing intensive calculations or intensive file writing/reading operations in this callback.
  • GetVehiclePos will return the old coordinates of the vehicle before this update.
