This function creates a vehicle at the specified location.

Its worth noting that the position of the vehicle is the center point of the vehicle, not its base. As such, you need to ensure that the z value (vertical axis) is some height above the ground. You can find the exact height using the client side function getElementDistanceFromCentreOfMassToBaseOfModel, or you can estimate it yourself and just spawn the vehicle so it drops to the ground.

Syntax

vehicle createVehicle ( int model, float x, float y, float z, [float rx, float ry, float rz, string numberplate] )

Required Arguments

  • model: The vehicle ID of the vehicle being created.
  • x: A floating point number representing the X coordinate on the map.
  • y: A floating point number representing the Y coordinate on the map.
  • z: A floating point number representing the Z coordinate on the map.

Optional Arguments

NOTE: When using optional arguments, you might need to supply all arguments before the one you wish to use. For more information on optional arguments, see optional arguments.

  • rx: A floating point number representing the rotation about the X axis in Degrees.
  • ry: A floating point number representing the rotation about the Y axis in Degrees.
  • rz: A floating point number representing the rotation about the Z axis in Degrees.
  • numberplate: A string that will go on the number plate of the car (max 8 letters). This is only applicable to cars.

Returns

Returns the vehicle element that was created. Returns false if the arguments are incorrect, or if the vehicle limit of 65535 is exceeded.

Using Trains

Trains are created using the createVehicle function. They are placed at the nearest point of the GTASA train pathing (railroad tracks) from their spawning point.

Example

Example 1: This example creates a vehicle five units to the right of a player when they type "createvehicle" and it's name in the console: 

-- call the 'consoleCreateVehicle' function when the "createvehicle" command is used:
addCommandHandler ( "createvehicle", "consoleCreateVehicle" )
function consoleCreateVehicle ( player, commandName, first, second )
   if ( player ) then
      -- calculate the position of the vehicle based on the player's position and rotation:
      local id, x, y, z, r, d = 0, 0, 0, 0, 0, 5
      r = getPlayerRotation ( player ) -- get the player's rotation
      x, y, z = getElementPosition ( player ) -- get the player's position
      x = x + ( ( math.cos ( math.rad ( r ) ) ) * d ) -- calculate the X position of the vehicle
      y = y + ( ( math.sin ( math.rad ( r ) ) ) * d ) -- calculate the Y position of the vehicle
      -- check whether the second argument exists (or whether the vehicle's name consists of two words):
      if ( second ) then
         id = getVehicleIDFromName ( first .. " " .. second ) -- get the vehicle's model ID from the name
      else
         id = getVehicleIDFromName ( first ) -- get the vehicle's model ID from the name
      end
      -- create the vehicle using the information gathered above:
      local vehicle = createVehicle ( id, x, y, z, 0, 0, r )
      if ( vehicle == false ) then -- if vehicle creation failed, give the player a message
         outputConsole ( "Failed to create vehicle.", player )
      end
   end
end

Example 2: Create a Hydra at the given position: 

createVehicle ( 520, 0, 0, 5 ) -- 520 is the model id for the Hydra
