On the game world, they have invented entity-component-system (
https://en.wikipedia.org/wiki/Entity_component_system ) data-driven
software architecture. The idea is to be very flexible with a "generic kind
of object" (entity), with typed component. An entity is only an integer.
The component are found inside a collection with the entity identifier.

So each component are allocated in it's own contener, so data are more
compact, and memory access appear less random.
