Bevy Master: ECS hub

ECS hub for Bevy 0.20+. Start here to set up a Bevy app, decide which components, resources, and systems own each piece of state, and load the right Bevy skill for the job.

Library target

Target: Bevy 0.20+ (tested against 0.20.0).

Who owns what (ECS)

For every piece of state, name:

• which component or resource owns it
• which system may mutate it
• which message or observer should observe it

Schedules replace a scene tree. Do not add an autoload, a signal bus, or a Node layer cake.

The Quick Start ECS page defines entities, components (Component), systems as functions, Query, Commands, Startup, and Update, plus .chain() for order. Messages, observers, resources, and app states are covered in their own skills. See those files before calling a type.
