Bevy XPBD v0.5.0

Bevy XPBD 0.5 is the final version of Bevy XPBD, and will be deprecated in favor of Avian, which is coming very, very soon. This release is primarily a Bevy 0.14 upgrade with very few breaking changes to ease migration. Avian 0.1 will have the majority of the changes.

The main changes and improvements in Bevy XPBD 0.5 are:

• Bevy 0.14 support.
• Transform propagation has significantly less overhead, as it is only performed for physics entities.
• Sensor colliders no longer contribute to mass properties.
• 2D heightfields take a Vec2 instead of a scalar value for scale.
• Some bug fixes, like rotation normalization in constraints to prevent explosive behavior.

Migration Guide

Sensor Mass Properties (#381)

Colliders with the Sensor component no longer contribute to the mass properties of rigid bodies. You can add mass for them by adding another collider that is not a sensor, or by manually adding mass properties with the MassPropertiesBundle or its components.

Additionally, the mass properties of Sensor colliders are no longer updated automatically, unless the Sensor component is removed.

PrepareSet System Set Order (#380)

Some PrepareSet system sets have changed order.

Before:

1. PreInit
2. PropagateTransforms
3. InitRigidBodies
4. InitMassProperties
5. InitColliders
6. InitTransforms
7. Finalize

After:

1. PreInit
2. InitRigidBodies
3. InitColliders
4. PropagateTransforms
5. InitMassProperties
6. InitTransforms
7. Finalize

ColliderHierarchyPlugin (#377)

Hierarchy and transform logic for colliders has been extracted from the ColliderBackendPlugin into a new ColliderHierarchyPlugin, which by default is included in the PhysicsPlugins plugin group.

If you are adding plugins manually, make sure you have both if you want that functionality.
