Bevy ECS

Structure a Bevy game in Rust around the Entity Component System: the App and plugins, components and resources, systems with queries, scheduling, and frame-rate-independent updates. Pins Bevy 0.16+ (code targets 0.16; Bevy's API shifts each minor release — match your Cargo.toml).

When to use

• Use when wiring a Bevy App, defining Component/Resource types, writing systems that query entities, ordering/filtering systems, or fixing borrow-conflict panics and frame-dependent movement.
• Use when Cargo.toml depends on bevy and code calls App::new(), add_systems, Query, or Commands.

When not to use: this is the ECS core. Deep rendering, custom shaders/ pipelines, UI layout, and audio are separate concerns. For engine-agnostic AI or procedural algorithms, pair with game-ai / procedural-gen.
