Struct NoIndirectDrawing

pub struct NoIndirectDrawing;

Add this component to a camera to disable indirect mode.

Indirect mode, automatically enabled on supported hardware, allows Bevy to offload transform and cull operations to the GPU, reducing CPU overhead. Doing this, however, reduces the amount of control that your app has over instancing decisions. In certain circumstances, you may want to disable indirect drawing so that your app can manually instance meshes as it sees fit. See the custom_shader_instancing example.

The vast majority of applications will not need to use this component, as it generally reduces rendering performance.

Note: This component should only be added when initially spawning a camera. Adding or removing after spawn can result in unspecified behavior.

Trait Implementations

impl Component for NoIndirectDrawing

where Self: Send + Sync + 'static,

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>].

fn register_required_components( requiree: ComponentId, components: &mut ComponentsRegistrator<'_>, required_components: &mut RequiredComponents, inheritance_depth: u16, recursion_check_stack: &mut Vec<ComponentId>, )

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.)

Called when registering this component, allowing mutable access to its ComponentHooks.

fn on_add() -> Option<for<'w> fn(_: DeferredWorld<'w>, _: HookContext)>

Gets the on_add ComponentHook for this Component if one is defined.

fn on_insert() -> Option<for<'w> fn(_: DeferredWorld<'w>, _: HookContext)>

Gets the on_insert ComponentHook for this Component if one is defined.

fn on_replace() -> Option<for<'w> fn(_: DeferredWorld<'w>, _: HookContext)>

Gets the on_replace ComponentHook for this Component if one is defined.

fn on_remove() -> Option<for<'w> fn(_: DeferredWorld<'w>, _: HookContext)>

Gets the on_remove ComponentHook for this Component if one is defined.

fn on_despawn() -> Option<for<'w> fn(_: DeferredWorld<'w>, _: HookContext)>

Gets the on_despawn ComponentHook for this Component if one is defined.

fn map_entities<E>(_this: &mut Self, _mapper: &mut E)

where E: EntityMapper,

Maps the entities on this component using the given EntityMapper. This is used to remap entities in contexts like scenes and entity cloning. When deriving Component, this is populated by annotating fields containing entities with #[entities]

impl Default for NoIndirectDrawing

fn default() -> NoIndirectDrawing

Returns the “default value” for a type.
