(Professionally planned course explanations will bring you the best viewing experience. The point is the algorithm. Mastering the algorithm can infinitely expand many cool functions (such as self-aiming, rays, prediction, radar display, etc.). The course is easy to understand from the shallower to the deeper, and you can learn the algorithm and code writing from the perspective of the box. This course includes the D3DHOOK chapter, which can fully understand the implementation principle and code writing of D3DHOOK, so as to achieve the most efficient flicker-free drawing effect.)
