With 0.17's release out we're into 0.18 development! Kicking off the development cycle with two new working groups focused on ergonomics:

  • font ergonomics
  • Async ECS ergonomics

As usual, many crates are bumping releases for 0.17, so we'll only explicitly be mentioning the ones that are new or have significant changes beyond the 0.17 compatibility release in the crates section this week.

Easy Screenshot Plugin

Taking screenshots is important for any game marketing, including Steam pages, social media posts, Bevy release notes, and even This Week in Bevy! #21235 introduces a new screenshot plugin to the bevy_dev_tools. Add the EasyScreenshotPlugin and configure the controls to press a key and get a new screenshot from your running application!

Remove Systems from Schedule

#20298 adds the ability to remove systems from a Schedule with remove_systems_in_set. For most uses, RunConditions are still the right approach, since removing a system will cause a schedule to get rebuilt. However removing a system will remove the cost of the RunCondition as well.

schedule.remove_systems_in_set(my_system, ScheduleCleanupPolicy::RemoveSystemsOnly);

ClearColor Solari

Solari ClearColor

#21350 adds the ability to use ClearColor with Solari.

AnimationTarget split

AnimationTarget is a Component that currently contains the AnimationPlayer Entity, and the AnimationTargetId. #20771 changes this to split the information into two components: AnimatedBy and AnimationTargetId.

  • The AnimatedBy(Entity) component is placed on the Entity being animated, and links to a different Entity with the AnimationPlayer.
  • The AnimationTargetId(Uuid) component holds a uuid, typically built from the name hierarchy of bones.

Together, this means different AnimationPlayers can have AnimationClips that target the same AnimationTargetId, and the AnimatedBy component can switch between them at runtime.

That is: Bones have ids through AnimationTargetId, and the choice of which AnimationPlayer controls the bone lives in AnimatedBy.

Enable prepass and shadows

#20999 introduces two new configurable functions to the Material traits:

  • enable_prepass
  • enable_shadows

These control whether or not the prepass or shadows are enabled for a given Material.

basically everything is done through individual png files, 1 png where every pixel color represents a tile/entity/etc, another set of pngs for tiles, each having ‘rules’ in the center

The goal is to decouple level layout from detailing and biomes, so every time you play every level could get randomized between any of the available biomes

from egui to bevy ui

Egui to Bevy UI

showcase

A port from egui to Bevy UI. This is a +3000 -1500 change, mainly because Bevy UI is more low-level but in turn you get more control. The UI is now in a separate crate and egui is no longer needed, so it's quite a simplification overall.

bevy_ui_root

bevy_window_as_ui_root

crate_release

bevy_window_as_ui_root spawns windows as independent UI roots. Ideal for debug widgets!

app.add_plugins(WindowAsUiRootPlugin);

commands.spawn((
  WindowAsUiRoot,
  BackgroundColor(Color::WHITE),
  children![(
    Text::new("Hello World!"),
    TextColor(Color::BLACK),
  )],
));

Insert the WindowAsUiRoot component on an entity and this plugin will:

  • Insert Node, Window, and Camera components if they don't already exist.
  • Connect the camera to the root node and window.
  • Automatically resize the window to match the root node's layout size (if it is auto or fixed).
