Time for action – the stationary camera

To implement a stationary camera in Mars Runner, perform the following steps:

1. 1. Create a new class file in the Mars Runner project called Camera.cs.

2. 2. Add the following using declaration to the Camera class file:

   using Microsoft.Xna.Framework;

3. 3. Add the following fields to the Camera class:

   #region Fields
   private Vector3 position = Vector3.Zero;
   private float rotation;
   
   private Vector3 lookAt;
   private Vector3 baseCameraReference = new Vector3(0, 0, 1);
   private bool needViewResync = true;
   
   private Matrix cachedViewMatrix;
   #endregion

4. 4. Add the following properties to the Camera class:

   #region Properties
   public Matrix Projection { get; private set; }
   public Matrix WideProjection { get; private set; }
   
   public Vector3 Position
   {
       get
       {
           return position;
       }
       set
       {
           position = value;
           updateLookAt();
       }
   }
   
   public float Rotation
   {
       get
       {
           return rotation;
       }
       set
       {
           rotation = value;
    ...
