<function name="SetVehicleParams" parent="Vehicle" type="classfunc"> <description> Sets the vehicle parameters for given vehicle. <note>Not all variables from the <page>VehicleParams</page> can be set.</note> <bug issue="2625">Because this method uses miles per hour but <page>Vehicle:GetVehicleParams</page> returns Hammer units per second, this method incorrectly modifies the vehicle engine's "boostMaxSpeed", "maxRevSpeed" and "maxSpeed" even when not explicitly set in a call to this method. **Workaround**: In order to retain the original values for these fields, call <page>Vehicle:GetVehicleParams</page> yourself, convert the mentioned fields from Hammer units per second to miles per hour (1 MPH &amp;asymp; 17.6 HU/s in this case) and add them to the table passed into the call to this setter. Avoid doing this repeatedly to avoid floating point inaccuracies over time (store the ready-calculated value for next time if possible).</bug> **Workaround**: In order to retain the original values for these fields, call <page>Vehicle:GetVehicleParams</page> yourself, convert the mentioned fields from Hammer units per second to miles per hour (1 MPH &asymp; 17.6 HU/s in this case) and add them to the table passed into the call to this setter.
