make me a working spacecraft in csharp

To make a working spacecraft in C#, we can use the Unity game engine which provides support for physics and 3D game development. Here is a basic outline of the steps involved in creating a spacecraft in Unity:

1. Open the Unity editor and create a new project.
2. Import any necessary assets such as 3D models or textures.
3. Create a new scene and add a planet with gravity.
4. Create a new game object for the spacecraft and add a rigidbody component to handle its physics.
5. Add thrusters to the spacecraft and write code to control their force and direction.
6. Create a camera and adjust its position and rotation to follow the spacecraft.
7. Write code to detect collisions between the spacecraft and other objects in the scene.
8. Test and refine the spacecraft's movement and behavior.

Here is some sample code as an example of how to control the spacecraft's thrusters:

main.cs
public class SpacecraftController : MonoBehaviour
{
    public Rigidbody spacecraftRigidbody;
    public float thrusterForce = 10f;

    void Update()
    {
        if (Input.GetKey(KeyCode.Space))
        {
            // apply forward force to thrusters
            spacecraftRigidbody.AddForce(transform.forward * thrusterForce);
        }

        if (Input.GetKey(KeyCode.LeftArrow))
        {
            // apply leftward force to thrusters
            spacecraftRigidbody.AddForce(transform.right * -thrusterForce);
        }

        if (Input.GetKey(KeyCode.RightArrow))
        {
            // apply rightward force to thrusters
            spacecraftRigidbody.AddForce(transform.right * thrusterForce);
        }
    }
}

This code uses the Input class to detect when the spacebar or arrow keys are pressed and applies a corresponding force to the spacecraft's rigidbody component. With some additional logic, this code could be expanded to move the spacecraft in any direction and respond to different input types.
