1. Add the following declaration to the
Fieldsregion of theCubeclass:private float rotation = 0f; private float zrotation = 0f;
2. Add an
Update()method to theCubeclass as follows:#region Update public void Update(GameTime gameTime) { rotation = MathHelper.WrapAngle(rotation + 0.05f); zrotation = MathHelper.WrapAngle(zrotation + 0.025f); } #endregion3. In the
Draw()method of theCubeclass, add two new items to the list of the generated matrices:Matrix rot = Matrix.CreateRotationY(rotation); Matrix zrot = Matrix.CreateRotationZ(zrotation);
4. Still in the
Draw()method, replace the current line that setseffect.Worldwith the following:effect.World = center * rot * zrot * scale * translate;
5. In the
Update()method of theCubeChaserGameclass, add the following line right before the existing call tobase.Update(gameTime):cube.Update(gameTime);
6. Execute your game and turn to face the cube:
