Physics body that simulates the behavior of a car.
This nodes implements all the physics logic needed to simulate a car. It is based on the raycast vehicle system commonly found in physics engines. You will need to add a CollisionShape for the main body of your vehicle and add VehicleWheel nodes for the wheels. You should also add a MeshInstance to this node for the 3D model of your car but this model should not include meshes for the wheels. You should control the vehicle by using the brake, engine_force, and steering properties and not change the position or orientation of this node directly.
Slows down the vehicle by applying a braking force. The vehicle is only slowed down if the wheels are in contact with a surface. The force you need to apply to adequately slow down your vehicle depends on the RigidBody.mass of the vehicle. For a vehicle with a mass set to 1000, try a value in the 25 - 30 range for hard braking.
Accelerates the vehicle by applying an engine force. The vehicle is only speed up if the wheels that have VehicleWheel.use_as_traction set to
true and are in contact with a surface. The RigidBody.mass of the vehicle has an effect on the acceleration of the vehicle. For a vehicle with a mass set to 1000, try a value in the 25 - 50 range for acceleration. Note that the simulation does not take the effect of gears into account, you will need to add logic for this if you wish to simulate gears.
A negative value will result in the vehicle reversing.
The steering angle for the vehicle. Setting this to a non-zero value will result in the vehicle turning when it’s moving. Wheels that have VehicleWheel.use_as_steering set to
true will automatically be rotated.
