Have you noticed there's also a respawn_delay option for CreateVehicle

Код:

// Add a Hydra to the game with a respawn time of 60 seconds - When a driver exits the vehicle.
    CreateVehicle(520, 2109.1763, 1503.0453, 32.2887, 82.2873, 0, 1, 60);

Instead of using that big code to respawn vehicles.. you can simply use CreateVehicle function.
