Time for action – player shots versus aliens

To implement how the player shots hit an alien craft, perform the following steps:

1. 1. Add the CrashSaucer() method to the EnemySaucer class as follows:

   #region HelperMethods
   public void CrashSaucer()
   {
       curvePoints[1] = Position;
       curvePoints[2].Y = -80;
       curvePoints[2].Z = 0;
       curveProgress = 0.0f;
       curveDelta = 0.5f;
       pitch = MathHelper.ToRadians(20);
       roll = MathHelper.ToRadians(-20);
       IsDestroyed = true;
   }
   #endregion

2. 2. Add the Collision Detection region to the ShotManager class as follows:

   #region Collision Detection
   public bool CheckPlayerShotHits(BoundingBox target)
   {
       foreach (PlayerShot shot in playerShots)
       {
           if (shot.IsActive)
           {
               if (target.Intersects(shot.Bounds))
               {
                   return true;
               }
           }
       }
   
       return false;
   }
   #endregion

3. 3. In the Update() method of the MarsRunnerPlayScreen class, add the following code just after shotManager has been...
