Model and Direction Setup

The original model and the entity direction (rotation) has been setup. Also, some process such as entity transformation matrices calculation has been moved to entity update function. The model exportation actually did not cause any trouble. I just use DirectX 8.0 export in milkshape 3D and it works...except a little glitch seen here, which I don't yet have a clear idea why:

The next thing I need to do is to add in animation control and setup a good control scheme or system. The system I used previously, a state system, might still be good, but I have to do a review about it and see if I should try another way, use the old way or improve on the old way. Another thing I should implement probably is a smooth rotation for the entity.
