VehicleWheel3D

Inherits: Node3D < Node < Object

A 3D physics body for a VehicleBody3D that simulates the behavior of a wheel.

Description

A node used as a child of a VehicleBody3D parent to simulate the behavior of one of its wheels. This node also acts as a collider to detect if the wheel is touching a surface.

Note: This class has known issues and isn't designed to provide realistic 3D vehicle physics. If you want advanced vehicle physics, you may need to write your own physics integration using another PhysicsBody3D class.

Property Descriptions

float brake = 0.0

• void set_brake ( float value )

• float get_brake ( )

Slows down the wheel by applying a braking force. The wheel is only slowed down if it is in contact with a surface. The force you need to apply to adequately slow down your vehicle depends on the RigidBody3D.mass of the vehicle. For a vehicle with a mass set to 1000, try a value in the 25 - 30 range for hard braking.
