public class CelestialObject { public Vector3 position; public Vector3 velocity; public float mass; public void CBUpdate(Vector3 newPosition, Vector3 newVelocity) { position = newPosition; velocity = newVelocity; } } // Example usage: CelestialObject mars = new CelestialObject(); Vector3 newPosition = /* calculate position using gravitational forces */; Vector3 newVelocity = /* calculate velocity using gravitational forces */; mars.CBUpdate(newPosition, newVelocity);In the example above, we have a basic CelestialObject class that has a position, velocity, and mass. We update its position and velocity using the CBUpdate method, which takes in the new position and velocity we've calculated using gravitational forces. Overall, the CelestialBody CBUpdate method is a useful tool for simulating the motion of celestial objects in a 3D space environment. It is likely part of a larger package library that provides a suite of tools for simulating astronomical systems.
