Struct SequenceNode 

pub struct SequenceNode { /* private fields */ }

Implementations

impl SequenceNode

pub fn new(children: Vec<Box<dyn BehaviorNode>>) -> SequenceNode

Create a new sequence node with the given children.

pub fn add_child(&mut self, child: Box<dyn BehaviorNode>)

Add a child behavior to the sequence.

pub fn len(&self) -> usize

Get the number of children.

pub fn is_empty(&self) -> bool

Check if the sequence is empty.

Trait Implementations

impl BehaviorNode for SequenceNode

fn tick<'life0, 'life1, 'async_trait>( &'life0 mut self, ctx: &'life1 Context, ) -> Pin<Box<dyn Future<Output = Result<NodeStatus, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, SequenceNode: 'async_trait,

Execute one tick of the behavior. Called repeatedly by the execution engine; should perform one unit of work, return quickly, and report progress via NodeStatus.

fn reset_self(&mut self)

Reset this node’s own local state, ignoring children.

fn name(&self) -> &str

Get the name of this behavior node.

fn children_mut(&mut self) -> Vec<&mut dyn BehaviorNode>

Return mutable references to this node’s child behaviors, in the order they should receive lifecycle events. Leaf nodes should not override this; composite nodes override it to expose their children.

fn active_capability(&self) -> Option<&str>

The capability this node implies should be published on /behavior/status while it’s actively being ticked; None for nodes with no such gate (the default). Composite nodes override this to forward whichever child is currently active.

fn reset<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Reset the behavior to its initial state.

fn on_init<'life0, 'life1, 'async_trait>( &'life0 mut self, ctx: &'life1 Context, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Called when the behavior is first initialized.

fn on_terminate<'life0, 'life1, 'async_trait>( &'life0 mut self, ctx: &'life1 Context, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Called when the behavior is being terminated.

impl Debug for SequenceNode

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
