[dependabot]

Updates the requirements on avian3d to permit the latest version.

Release notes

Sourced from avian3d's releases.

Bevy XPBD v0.4.0

Bevy XPBD 0.4 features several new features, bug fixes, and quality of life improvements. Here are some highlights:

• Generic colliders: Bevy XPBD no longer relies on just Collider for collision detection. You can implement custom collision backends!
• Parry and Nalgebra are optional: The Parry and Nalgebra dependencies are now behind feature flags (enabled by default). If you don't need collision detection or have a custom collision backend, you can disable them!
• Access contact impulses: It is often useful to know how strong collisions are. This information is now available in Collision events and the Collisions resource.
• Debug render contacts: Contact normals and impulses can now be debug rendered.
• Layer rework: Collision layers have been reworked to be more versatile and explicit with less footguns.
• Bevy 0.13 support: Bevy XPBD has been updated to the latest version of Bevy.
• Colliders from primitives: Colliders can be created from the new geometric primitives introduced in Bevy 0.13.
• PhysicsGizmos gizmo config group: Debug rendering has its own gizmo configuration instead of using the global configuration.

Check out the announcement blog post for a more in-depth overview of what's changed and why. A more complete changelog can also be found after the migration guide below.

Migration Guide

Default Features (#327)

The default Collider now requires either the parry-f32 or parry-f64 feature depending on the precision you are using for Bevy XPBD. However, if you don't need colliders or have a custom collision backend, you can leave the feature disabled.

Layer Rework (#313)

Collision layers have been reworked, see #313.

• Groups are now called memberships and masks are called filters. This also matches Rapier's naming.
• Memberships and filters use a type called LayerMask, which is a bitmask for layers and a newtype for u32.
• All methods like add_group, remove_mask, and so on have been removed. Instead, modify the properties directly.

let layers1 = CollisionLayers::new(0b00010, 0b0111);
let layers2 = CollisionLayers::new(GameLayer::Player, [GameLayer::Enemy, GameLayer::Ground]);
let layers3 = CollisionLayers::new(LayerMask(0b0001), LayerMask::ALL);

Modifying layers is now done by modifying the memberships or filters directly:

layers.memberships.remove(GameLayer::Environment);
layers.filters.add([GameLayer::Environment, GameLayer::Tree]);
// Bitwise ops also work since we're accessing the bitmasks/layermasks directly.
layers.memberships |= GameLayer::Player; // You could also use a bitmask like 0b0010.

Debug rendering

The PhysicsDebugConfig resource and PhysicsDebugRenderer system parameter have been removed in favor of the new PhysicsGizmos gizmo configuration group.
