Expand description

A possibly-recursive set of possible tasks.

You need to implement at least two methods: is_valid and add_own_tasks.

Required Methods§

Source

fn is_valid( &self, tick: u64, state: StateDiffRef<'_, D>, agent: AgentId, ) -> bool

Returns if the behavior is valid for the given agent in the given world state.

Source

fn add_own_tasks( &self, tick: u64, state: StateDiffRef<'_, D>, agent: AgentId, tasks: &mut Vec<Box<dyn Task<D>>>, )

Collects valid tasks for the given agent in the given world state.

Provided Methods§

Source

fn get_dependent_behaviors(&self) -> &'static [&'static dyn Behavior<D>]

Returns dependent behaviors.

Source

fn add_tasks( &self, tick: u64, state: StateDiffRef<'_, D>, agent: AgentId, tasks: &mut Vec<Box<dyn Task<D>>>, )

Helper method to recursively collect all valid tasks for the given agent in the given world state.

It will not do anything if the behavior is invalid at that point.
