Avian is an ECS-based 2D and 3D physics engine for Bevy, a refreshingly simple data-driven game engine built in Rust. Avian prioritizes ergonomics and modularity, with a focus on providing a native ECS-driven user experience.

It is the next evolution of my previous physics engine Bevy XPBD, with a completely rewritten contact solver, improved performance, a reworked structure, and numerous other improvements over its predecessor. This will be covered in detail later into the post.

Now, you can use the numerous components and resources provided by Avian to add physics behavior to your entities. For example, turning an entity into a rigid body with a collider is as simple as adding the RigidBody and Collider components, and an initial velocity can be specified using LinearVelocity:

As stated earlier, Avian isn’t actually my first physics engine. Instead, it is the rebranded successor of my previous physics engine Bevy XPBD. The rest of this post will focus on the rebrand and what is new from Bevy XPBD 0.4.
