copied!<p>Rather than addressing the structuring of your data, I'd just like to offer perspective on how I've done stuff like this in the past.</p> <p>The game engine has a list of managers responsible for various systems in the game (InputManager, PhysicsManager, RenderManager, etc...).</p> <p>Most things in the 3D world are represented by an Object class, and each Object can have any number of Components. Each component is responsible for different aspects of the object's behavior (RenderComponent, PhysicsComponent, etc...).</p> <p>The physics component was responsible for loading the physics mesh, and giving it all of the necessary properties like mass, density, center of mass, inertia response data, and more. This component also stored information about the physics model once is was in the world, like a position, rotation, linear velocity, angular velocity, and more.</p> <p>The PhysicsManager had knowledge of every physics mesh that had been loaded by any physics components, this allowed that manager to handle all physics-related tasks, such as collision detection, dispatching collision messages, doing physics ray casts.</p> <p>If we wanted specialized behavior that only a few objects would need we would create a component for it, and have that component manipulate data like velocity, or friction, and those changes would be seen by the PhysicsManager and accounted for in the physics simulation.</p> <p>As far as the data structure goes, you can have the system I mentioned above and structure it in several ways. Generally the Objects are kept in either a Vector or Map, and Components are in a Vector or List on the Object. As far as physics information goes, the PhysicsManager has a list of all physics objects, which can be stored in an Array/Vector, and the PhysicsComponent has a copy of its position, velocity, and other data so that it can do anything that it needs to have that data manipulated by the physics manager. For example if you wanted to alter the velocity of an Object you'd just tell the PhysicsComponent, it would alter its velocity value and then notify the PhysicsManager.</p> <p>I talk more about the subject of object/component engine structure here: <a href="https://gamedev.stackexchange.com/a/23578/12611">https://gamedev.stackexchange.com/a/23578/12611</a></p>
