Bevy Remote Protocol, TheLightmapper, and particles
2024-12-16
The Bevy Remote Protocol is still capturing the attention of anyone with an editor available. We've now seen neovim, emacs, egui, standalone, and VSCode based inspectors using the new Bevy Remote Protocol.
Meanwhile interesting lightmapping experiments are happening with TheLightmapper/Bevy workflows, picking through portals, and more.
A number of PRs made it in this week, including really interesting reflection, curve, and event source features.
SystemInput tuples
#16814 introduces the ability to accept arbitrary tuples of SystemInputs. While only 8-arity tuples are implemented in core, 9+ can be added in userland if necessary.
fn by_mut((InMut(a), In(b)): (InMut<usize>, In<usize>)) {
*a += b;
}
let mut world = World::new();
let mut by_mut = IntoSystem::into_system(by_mut);
by_mut.initialize(&mut world);
let mut a = 10;
let b = 5;
by_mut.run((&mut a, b), &mut world);
assert_eq!(*a, 15);
Event Source Location Tracking
#16778 adds core::panic::Location to EventId which allows users to figure out where an event was sent from.
This functionality is behind the tracking_change_detection feature.
fn apply_damage_to_health(
mut dmg_events: EventReader<DealDamage>,
) {
for (event, event_id) in dmg_events.read_with_id() {
info!(
"Applying {} damage, triggered by {}",
event.amount, event_id.caller
);
…
2024-12-12T01:21:50.126827Z INFO event: Applying 9 damage, triggered by examples/ecs/event.rs:47:16
bevy ui debug overlay
As of #16693 the bevy ui debug overlay is rendered by the ui renderer and lives behind the bevy_ui_debug feature.
cargo run --example testbed_ui --features bevy_ui_debug
Derivative access patterns for curves
#16503 introduces the ability to access the derivatives of curves.
let points = [
vec2(-1.0, -20.0),
vec2(3.0, 2.0),
vec2(5.0, 3.0),
vec2(9.0, 8.0),
];
// A cubic spline curve that goes through `points`.
let curve = CubicCardinalSpline::new(0.3, points).to_curve().unwrap();
// Calling `with_derivative` causes derivative output to be included in the output of the curve API.
let curve_with_derivative = curve.with_derivative();
// A `Curve<f32>` that outputs the speed of the original.
let speed_curve = curve_with_derivative.map(|x| x.derivative.norm());
Make StandardMaterial bindless
#16644 takes advantage of the work in #16368 to enable using bindless textures in Bevy's StandardMaterial
bevy_reflect: Generic and Variadic Functions
#15074 introduces the ability to overload reflected functions. This adds support for generic functions:
let reflect_add = add::<i32>
.into_function()
.with_overload(add::<u32>)
.with_overload(add::<f32>);
as well as variadic functions
// Supports 1 to 4 arguments
let multiply_all = (|a: i32| a)
.into_function()
.with_overload(|a: i32, b: i32| a * b)
.with_overload(|a: i32, b: i32, c: i32| a * b * c)
.with_overload(|a: i32, b: i32, c: i32, d: i32| a * b * c * d);

Crates
New releases to crates.io and substantial updates to existing projects
ramp_gen
crate_release
A utility to generate functions for rust and wgsl similar to Blender's "Color Ramp" node.
iyes_progress v0.13.1
crate_release
iyes_progress is a crate to help you with creating loading screens where you might need to do arbitrary complex work, beyond just loading assets. It can keep track of everything for you and transition your state when all of your stuff reports completion.
This semver-compatible release adds a couple of new big features:
- "Progress as Entities". This is an additional/alternative way of tracking progress. You can add the new
ProgressEntity<S>component to entities and store progress there. This progress will be summed up and counted alongside all progress reported via the other existing mechanisms (returned by systems, stored in manual entries, etc.). - Progress from background tasks/threads. Give them a
ProgressSenderand they can send their progress updates, whichiyes_progresswill apply to their respective progress tracker entries. Requires the"async"cargo feature.
berdicles
crate_release
General purpose instancing and projectile system
0.3 brings a new ribbon shader, support for custom instance buffers, and more
bevy_vox_scene 0.17
crate_release
bevy_vox_scene is a plugin for loading Magica Voxel files directly in bevy as usable meshes.
0.17 brings support for importing Magica Voxel's cloud materials as fog volumes, using the new fog density image feature in bevy 0.15. This means that bevy_vox_scene now supports all of Magica Voxel's material types.
bevy_minibuffer
crate_release
A gamedev console in your application with support for tab completion, user prompts, command running, and more. Currently supports Bevy 0.14
Beet 0.0.4
crate_release
Similarly to how observers introduced entities as events, beet introduces entities as control flow.
Why its cool
- Its modular: instead of creating a new type for each state/behavior, add another child entity.
- Its paradigm agnostic: At its core Beet simply provides tools to describe whether a behavior entity is running, the rest is just various ways that behaviors can be connected
