This function is used to change the handling data of a vehicle.

*Note: This function has not merged into the 1.1 nightly builds yet! It will only work if you have a custom build of the handling branch.

Syntax

bool setVehicleHandling ( element theVehicle, string property, int/float/bool/table value )

Required Arguments

  • theVehicle: The vehicle you wish to set the handling of.
  • property: The property you wish to set the handling of the vehicle to.
  • value: The value of the property you wish to set the handling of the vehicle to.

Returns

Returns true if the handling was set successfully, false otherwise. See below a list of valid propertys and their required values:

Example

function massChange ( me, command, mass )
   veh = getPedOccupiedVehicle ( me ) -- get the ped's occupied vehicle
   if speed and veh then  -- if the mass is given and has a veh
       setVehicleHandling ( veh, "mass", tonumber ( mass ) ) -- set handling
   end
end

addCommandHandler ( "changemass", massChange )
