bevy_serialization_extras

A library for component oriented serialization.

Features

  • Out of the box serialization Through plugins for components
// Component <-> WrapperComponent
.add_plugins(SerializeComponentFor::<AsyncCollider, ColliderFlag>::default())

// Asset <-> WrapperComponent
.add_plugins(SerializeAssetFor::<MeshMaterial3d<StandardMaterial>, MaterialFlag3d>::default())
// Query -> Component, 
.add_plugins(SerializeQueryFor::<Linkage, ImpulseJoint, JointFlag>::default())
  • Serialization of groups of enities that compose an asset into their singular asset equivillent, and vice-versa

A visualization util to list serializable/unserializable components(W.I.P) [bevy_serialization_core]

Visualize and edit 3rd party components that do not Reflect

E.G: Edit Rapier's ImpulseJoint through JointFlag [bevy_serialization_physics]

Serialize a collection of entities into an Asset that is composed of them

E.G: serialize the parts of a robot into a Urdf [bevy_serialization_assemble]

//(entity_0, ... entity_n) -> Asset
// [UNIMPLEMENTED] Asset -> (entity_0, ... entity_n)
.add_plugins(SerializeManyAsOneFor::<LinkQuery, Urdf>::default())

Why bevy_serialization_extras?

  • bevy_serialization_extras is built ontop of bevy_reflect, not serde. No need to double dip to serialize.

  • bevy_serialization_extras allows regular serialization into .ron via moonshine_save + allows converting serializables into more stable file formats via bevy_serialization_assemble.

serde serialization:

world <--> scene.json

bevy_serialziation_extras:

(object) <--> (partA, partB) <--> .file
(person) (body + arm_0...arm_n + leg_0..leg_n) <--> .file
world <--> scene.ron

This is good for creating editors in bevy.
