Struct Gizmo

pub struct Gizmo {
    pub handle: Handle<GizmoAsset>,
    pub line_config: GizmoLineConfig,
    pub depth_bias: f32,
}

A component that draws the gizmos of a GizmoAsset.

When drawing a greater number of static lines a Gizmo component can have far better performance than the Gizmos system parameter, but the system parameter will perform better for smaller lines that update often.

Example

fn system(
    mut commands: Commands,
    mut gizmo_assets: ResMut<Assets<GizmoAsset>>,
) {
    let mut gizmo = GizmoAsset::default();

    gizmo.sphere(Vec3::ZERO, 1., RED);

    commands.spawn(Gizmo {
        handle: gizmo_assets.add(gizmo),
        line_config: GizmoLineConfig {
            width: 4.,
            ..default()
        },
        ..default()
    });
}

Fields

handle: Handle<GizmoAsset>

The handle to the gizmo to draw.

line_config: GizmoLineConfig

The line specific configuration for this gizmo.

depth_bias: f32

How closer to the camera than real geometry the gizmo should be.

In 2D this setting has no effect and is effectively always -1.

Value between -1 and 1 (inclusive).

• 0 means that there is no change to the gizmo position when rendering
• 1 means it is furthest away from camera as possible
• -1 means that it will always render in front of other things.

This is typically useful if you are drawing wireframes on top of polygons and your wireframe is z-fighting (flickering on/off) with your main model. You would set this value to a negative number close to 0.

Trait Implementations

impl Clone for Gizmo

fn clone(&self) -> Gizmo

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Component for Gizmo

where Self: Send + Sync + 'static,

Required Components: Transform.

A component’s Required Components are inserted whenever it is inserted. Note that this will also insert the required components of the required components, recursively, in depth-first order.

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::Table

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have [Component<Mutability = Mutable>], while immutable components will instead have [Component<Mutability = Immutable>].

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn register_component_hooks(hooks: &mut ComponentHooks)

👎Deprecated since 0.16.0: Use the individual hook methods instead (e.g., Component::on_add, etc.)
