Struct RapierContextLinkResolver 

pub struct RapierContextLinkResolver<'w, 's> { /* private fields */ }

Finds the Rapier context of the entities being initialized without a RapierContextEntityLink.

Such an entity joins the context of its closest ancestor with a RapierContextEntityLink, or the DefaultRapierContext if it has none.

Implementations

impl RapierContextLinkResolver<'_, '_>

pub fn resolve( &self, entity: Entity, link: Option<&RapierContextEntityLink>, commands: &mut Commands<'_, '_>, ) -> Option<Entity>

The context of entity, given its current link.

If link is None, the resolved context is inserted as the entity’s RapierContextEntityLink. Returns None if no context was found.

Trait Implementations

impl<'w, 's> ReadOnlySystemParam for RapierContextLinkResolver<'w, 's>

where Query<'w, 's, Entity, With<DefaultRapierContext>>: ReadOnlySystemParam, Query<'w, 's, &'static ChildOf>: ReadOnlySystemParam, Query<'w, 's, &'static RapierContextEntityLink>: ReadOnlySystemParam,

impl SystemParam for RapierContextLinkResolver<'_, '_>

type State = FetchState

Used to store data which persists across invocations of a system.

type Item<'w, 's> = RapierContextLinkResolver<'w, 's>

The item type returned when constructing this system param. The value of this associated type should be Self, instantiated with new lifetimes.

fn init_state(world: &mut World) -> Self::State

Creates a new instance of this param’s State.

fn init_access( state: &Self::State, system_meta: &mut SystemMeta, system_access: &mut SystemAccess, world: &mut World, )

Registers any World access used by this SystemParam.

fn apply(state: &mut Self::State, system_meta: &SystemMeta, world: &mut World)

Applies any deferred mutations stored in this SystemParam’s state. This is used to apply Commands during ApplyDeferred.

fn queue( state: &mut Self::State, system_meta: &SystemMeta, world: DeferredWorld<'_>, )

Queues any deferred mutations to be applied at the next ApplyDeferred.

unsafe fn get_param<'w, 's>( state: &'s mut Self::State, system_meta: &SystemMeta, world: UnsafeWorldCell<'w>, change_tick: Tick, ) -> Result<Self::Item<'w, 's>, SystemParamValidationError>

Creates a parameter to be passed into a SystemParamFunction.
