For the physics engine, it was simply heard before, and vaguely considered to be a module that encapsulates the laws of physics, and if we need to simulate the real movement of the game, we use it. As for how the physics engine simulates real motion and how to use the physics engine, when it is used, the slightest concept is not.
Recently, because of the working relationship, in the existing game engine, integrated Havok this physics engine. The first feeling is that the amount of information is slightly larger, the second feeling is not know what to take this physics engine to achieve what effect, so is also very melancholy, but overall there is a general plan how to complete this challenging task.
The plan is as follows:
1. Understand what the physics engine is and what the physics engine can do.
2. Understand how the physics engine works and how to use the physics engine.
3, understand the existing game engine, and how, where, when to use the physical engine and expected to achieve the effect.
