How to keep track of all game entities?
To keep track of all game entities, you need to set up an Entity Manager. The Entity Manager keeps track of all entities that are active in a game. The entity manager stores each game entity in a container. The best container to use is a scenegraph.
How does the physics engine determine the position and velocity of an entity?
The physics engine determines the position and velocity of an entity. It does this by integrating the external forces acting on the entity. The most common external force acting on an entity is gravity. By integrating the force of gravity we get the velocity and position of the entity.
