Modify the code for 3d animation.

Also you can create a 3d animation to this example using these lines of codes.

First initilize a float varible to the animation.

float val = 0.0f;

then in Update() metord increment the valuve to change the position.

  val = val + 0.8f;

finally in the Draw() metord add  the val variable to change the position.

effect.World = transforms[mesh.ParentBone.Index] * Matrix.CreateTranslation(30.0f+val, -40.0f, -400.0f-val);

then after you press F5 you are ready to play the animation.
