The movement physics under went another rewrite a little while ago bringing them to what will be the final version functionality wise for the semester since there is much more to be done. That being said they improved a great deal in both concept and implementation and now, in my opinion work better then the movement in Half-Life.

I say this because the Half-Life engine suffers from the problem of compounding simultaneous multidimensional movement requests. Meaning, if your Resource has a movement speed defined as say 10 and you hold both the forward and side strafe keys at the same time to move at a 45 degree angle in Half-Life it would take the first input, and add 10 to the Y component of the movement vector. Then it would process the side strafe input and add 10 to the X component of the movement vector. The resulting vector would have a magnitude of ~14.142 units. Which in my mind, if you define 10 as the speed for something in your world then that should be the speed no if ands or buts. So in my code I accumulate all the input, then based on the input I modify the angle not the magnitude of the resulting vector so no matter how you move the magnitude of the vector will be 10. Actually saves some computation as well.

Additionally, I’ve spent time adapting my BSP loading and rendering code into the Framework these last couple days. This is going well and actually a bit faster then I expected. The BSPManagerServices now successfully loads in a v30 BSP file. There is quite a bit of a paradigm shift in how the data is rendered though which took some thinking through to come up with the new methods needed. The renderer is almost done ( Still writing functions to give it efficient access to the geometric data loaded from the BSP file ). Once I finish that I need to write some functions for the SimulationResourceManagerService which will locate each Resource it manages in a Leaf of the BSP tree when ever they move and dynamically attach them to the BSPLeafNodes as they move around. That should be it then. The new Framework should be caught up to where the old engine was before this semester started.

So exciting things to come as I move into some of the less essential things like config files (finally!) and collision detection!
