Then, create one more class which should extend Sprite and give it the name FPSController. How to do it... FPSController class encapsulates all the functionalities of the FPS camera. It is going to receive the reference to the scene camera and apply FPS behavior "behind the curtain". getMaterial("bakedAll [Plane0"). walk(); } } } 46 Chapter 2 How it works... FPSController class looks a tad scary, but that is only at first glance. First we pass the following arguments into the constructor: 1. camera: Camera3D reference (here Camera3D, by the way, is the most appropriate one for FPS).

The third parameter is an amount of bump amplitude to be embedded into the normal map. The higher the value, the more detailed the normal map becomes. 05, but you can experiment with it to achieve a desired result. See also In Chapter 8, Prefab3D, refer to the recipe Normal Mapping in Prefab. Getting your hands dirty with Pixel Bender materials The Away3D materials package has got a unique group of materials with one common feature which is Pixel Bender shaders. It is easy to identify these materials.

However, one must be careful not to overdo it because of performance considerations. Next is an optional parameter for the height map. The height map is usually a grayscale image ranging from black to white and representing height information where the complete black is deepest and full white indicates the highest region. In this example, we want to get a bumpy relief effect for our model. So we define a height map, which is just a grayscale version of the sphere default texture, to embed bump information into our normal map.
