Bevy Game Engine

A refreshingly simple data-driven game engine built in Rust. Free and Open Source Forever!

Data Driven All engine and game logic uses Bevy ECS, a custom Entity Component System

• Fast: Massively Parallel and Cache-Friendly. The fastest ECS according to some benchmarks
• Simple: Components are Rust structs, Systems are Rust functions
• Capable: Queries, Global Resources, Local Resources, Change Detection, Lock-Free Parallel Scheduler

2D Renderer Render real-time 2D graphics for games and apps

• Features: sprite sheets, dynamic texture atlases, cameras, textures, and materials
• Extensible: custom shaders, materials, and render pipelines
• Common Core: builds on top of Bevy's Render Graph

3D Renderer A modern and flexible 3D renderer

• Features: lights, cameras, meshes, textures, materials, gltf loading
• Extensible: custom shaders, materials, and render pipelines
• Common Core: built on top of Bevy's Render Graph

Render Graph Compose custom render pipelines using a graph structure

• Parallel: Render Graphs are automatically rendered in parallel
• Modular: Build composable and reusable render logic using Render Graph nodes
• Backend Agnostic: Not tied to a specific graphics api

Bevy UI A custom ECS-driven UI framework built specifically for Bevy

• Built directly on top of Bevy's ECS, Renderer, and Scene plugins
• Compose UIs dynamically in code or declaratively using the Bevy Scene format
• Use a familiar "flex box" model to layout your UIs

Scenes Create, save, and load ECS worlds using Bevy's Scene system

• Loading: Loading scenes preserves entity IDs (useful for save games)
• Instancing: Instancing creates linked duplicates of scenes with new entity IDs
• Hot Reloading: Changes to scene files are automatically applied to running apps

Sound Load audio files and play them on demand

• Load mp3 audio files as Assets
• Play audio files using the AudioOutput resource
