Bevy Jam 6 starts, Hot Reloading Rust, and bevy_seedling

2025-06-02

Bevy Jam 6 starts on the 31st and runs for 9 days, ending the next Sunday night. There are a number of alpha creations worth testing!

Get jammin!

StateScoped

#19435 introduces the ability to clear events when entering a state, not just exiting.

app
  .add_event::<MyGameEvent>()
  .clear_events_on_exit_state::<MyGameEvent>(GameState::Play);

While #19401 enables state scoped events on computed states.

Image::resize_in_place

#19410 introduces a new Image::resize_in_place method to

new box_shadow example

box_shadow

#19345 introduces a new, configurable, box-shadow example.

RustWeek Examples

cooldowns

Following on the RustWeek work, a new usages category was added to the examples and a cooldown example was introduced in #19234

context menu

#19245 also adds a context menu.

Dir4

Bevy has Dir2 and Dir3 types that wrap normalized Vec2 and Vec3, but there isn't a Dir4 type that wraps a normalized Vec4. That Dir4 was added in #19223.

Hdr Component

In #18873 the Camera::hdr field was separated out into a new component: Hdr.

commands.spawn((Camera3d, Hdr));

which allows it to be required by other functionality like Bloom

#[require(Hdr)]
pub struct Bloom;

Remove Shader weak_handles

#19137 introduced the new load_shader_library macro which is being put to good use in a number of PRs to remove the use of weak_handles in accordance with #19024
