How does the Bevy Resources System work?

[MasonJohnHawver42]

What data structures are used to create the bevy resources system? or here in the source code is this system outlined? I want to recreate this system in C++ for my own game engine. My current implementation uses an array of void pointers and a hash map that maps strings to the index of a void ptr.

Search for insert_resource in bevy::ecs::World.
A resource is a component without an entity attached.
Other projects might also be useful:

• HECS: Bevy's ECS is based on that
• Fyrox: 3D ECS game engine with a Scene Editor

Good luck with your engine!
