What it does

Bevy Picking is an agent skill from nolantait/bevy-starter. Reference for Bevy's picking system — pointer events, backends, hover/click/drag observers, sprite picking, UI picking, and mesh picking.

Its SKILL.md is about 930 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Game Development. The repository describes itself as: A minimalist starter for bevy and rust. The licence is MIT.

When your agent uses it

Game Development work in your project

Example prompts

“/bevy-picking”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

Input → update pointers → PointerInput events
Update PointerLocation components
Backends read locations → produce PointerHits
Build HoverMap (topmost entity wins)
Generate higher-level Pointer events

What it can do on your machine

Read from SKILL.md and the folder at commit dd6f56b. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are rust).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Bevy Picking loads about 927 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 292 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~38
When it runs · the whole SKILL.md, loaded when a task matches: ~927

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Core concept

Pointer is an abstract representation of user input at a screen location. Backends read PointerLocation components and produce PointerHits events. An app can have multiple backends active at once.

rust

pub struct PointerHits {
  pub pointer: PointerId,
  pub picks: Vec<(Entity, HitData)>,
  pub order: f32,
}

A pointer's location targets a NormalizedRenderTarget, which can be one of: Windows, Images, or GPU Texture Views.

PointerHits feed the generic picking plugins, which produce higher-level Pointer<E> events that we react to with an Observer or MessageReader.

Default picking plugins

DefaultPickingPlugins (included with DefaultPlugins when bevy_picking feature enabled) contains:

InteractionPlugin — generates pointer events, handles bubbling
PickingPlugin — sets up core picking infrastructure and PickingSettings
PointerInputPlugin — mouse and touch events

Pointer event types

Hovering

Pointer<Over> — pointer entered entity bounds
Pointer<Move> — pointer moving over entity
Pointer<Out> — pointer left entity bounds

Clicking

Pointer<Press> / Pointer<Release> — button pressed/released
Pointer<Click> — press + release on same entity

Dragging

Pointer<DragStart> / Pointer<Drag> / Pointer<DragEnd>
Pointer<DragEnter> / Pointer<DragOver> / Pointer<DragDrop> / Pointer<DragLeave>

Picking sprites

Enable with Pickable component:

rust

commands.spawn((
  Sprite::from_color(GREEN, Vec2::new(100., 100.)),
  Pickable::default(),
)).observe(|hover: On<Pointer<Over>>, mut sprites: Query<&mut Sprite>| {
  sprites.get_mut(hover.entity).unwrap().color = YELLOW.into();
});

Picking UI

UI nodes are pickable by default. Sprites need a Pickable component to opt in. Attach observers to specific elements:

rust

commands.spawn(button()).observe(|click: On<Pointer<Click>>| {
  info!("Button clicked!");
});

Picking meshes (3D)

Add MeshPickingPlugin. Use observers on mesh entities:

rust

commands.spawn((
  Mesh3d(meshes.add(Cuboid::from_length(5.))),
  MeshMaterial3d(materials.add(Color::from(SILVER))),
)).observe(|drag: On<Pointer<Drag>>, mut transforms: Query<&mut Transform>| {
  let mut t = transforms.get_mut(drag.entity).unwrap();
  t.rotate_y(drag.delta.x * 0.02);
  t.rotate_x(drag.delta.y * 0.02);
});

Ignoring entities

rust

Pickable::IGNORE  // disables picking on this entity

Set MeshPickingSettings::require_markers to true for opt-in mesh picking.

Picking pipeline order

Input → update pointers → PointerInput events
Update PointerLocation components
Backends read locations → produce PointerHits
Build HoverMap (topmost entity wins)
Generate higher-level Pointer<E> events

Within a frame:

Out -> Leave -> DragLeave
DragEnter -> Enter -> Over

Then any of the following in any order:

Movement: DragStart -> Drag -> DragOver -> Move
Button press: Press or Click -> Release -> DragDrop -> DragEnd -> DragLeave
Cancellation: Cancel

Between frames the interaction state machine manages:

Move over target: Over -> Enter -> Move -> Leave -> Out
Press on target: Press -> Click -> Release
Drag target: DragStart -> Drag -> DragEnd
Drag something over target: DragEnter -> DragOver -> DragDrop -> DragLeave
Cancel: no other events follow Cancel for that pointer.
