Struct GoalStack 

pub struct GoalStack { /* private fields */ }

A priority-ordered collection of goals for one agent.

The active goal is always the one with the highest priority. If two goals share the same priority the one added first wins (stable sort).

Implementations

impl GoalStack

pub fn new() -> Self

pub fn push(&mut self, goal: Goal)

Push a new goal. The stack is re-sorted automatically.

pub fn remove(&mut self, name: &str)

Remove the goal with name.

pub fn active(&self) -> Option<&Goal>

Return the highest-priority active goal, if any.

pub fn tick(&mut self, dt: f32)

Advance simulation time and prune expired goals.

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn iter(&self) -> impl Iterator<Item = &Goal>

Iterate all goals (highest priority first).

pub fn has_goal(&self, name: &str) -> bool

True if any goal with name exists and is not expired.

pub fn sim_time(&self) -> f32
