They can be defined dynamically, so that the decision of whether to invoke the method is made immediately prior to the call itself. Dynamic pointcuts therefore have information about the current state of the application (including ThreadLocal contents) and the parameters to be passed to the method. Listing 5-37 defines a pointcut that will be used to avoid calling the advice logic if the current user is an administrator. The class implements the same matches method as was used in Listing 5-35 for static pointcuts. This allows the framework to avoid generating proxies for inappropriate types. A second (abstract) matches method is then implemented to determine at runtime whether the advice should be applied.

In keyframed animation, you store a static model mesh for each frame of the animation. If you were to animate the model in Figure 12-1, you would need to export four different static meshes (the fifth is identical to the first). This animation is called keyframed because only the frames with the main changes the keyframes are exported. In the animation shown in Figure 12-1, you will need to add tweening between the first and second animation frames, to make the animation appear smooth. (Tweening refers to generating the intermediate frames between keyframes.) However, you don t necessarily need to create all of the frames beforehand, because you can obtain them by interpolating between the first and second frames. For example, using a linear interpolation, the position of each vertex in the mesh is calculated between the first and second frames. When you load the animated model, you create as many frames between the keyframes as you need to make the animation go smoothly, based on the few keyframes stored inside the model, and store them in memory. Then they are ready to be used for rendering the animation. One of the advantages of keyframed animation is that it s fast, because all interpolation calculations have been done at startup. All the animation frames are stored in memory, and during the animation, you only need to change to the next mesh in the animation each frame. However, a disadvantage of this method is that it s necessary to store all the model meshes in memory. If a model needs 100 animation frames, it s necessary to store its mesh 100 times.

You created the Terrain class and its effect and material classes in 11. To add these classes to the project, you first need to create the Shapes, Materials, and Effects folders. Then add the Terrain class to the Shapes folder, the TerrainEffect class to the Effects folder, and all the material classes to the Materials folder. You also need to add the VertexPositionNormalTangentBinormalTexture class used by the Terrain class to the Helpers folder in the XNA TPS project. Finally, add the terrain assets (height map, textures, and effects) to the XNA TPS Content project. To add these assets to the Content project, create a few different folders: the Terrains folder, used to store the terrain s height map; the Textures folder, used to store the game textures; and the Effects folder, used to store the effects. After adding all the assets to their folders, remember to modify the properties of the terrain s height map, changing its Build Action property to None and its Copy to Output Directory property to Copy if Newer.
