Struct MotionGraph 

pub struct MotionGraph {
    pub entry_state: Option<String>,
    /* private fields */
}

Animation state machine – a collection of states connected by transitions.

Fields

entry_state: Option<String>

Name of the state to enter on startup.

Implementations

impl MotionGraph

pub fn new() -> Self

Create an empty motion graph.

pub fn add_state(&mut self, state: MotionState)

Register a state. If this is the first state and no entry state has been set, it becomes the entry state automatically.

pub fn add_transition(&mut self, transition: MotionTransition)

Register a transition edge.

pub fn state_count(&self) -> usize

Total number of registered states.

pub fn transition_count(&self) -> usize

Total number of registered transitions.

pub fn get_state(&self, name: &str) -> Option<&MotionState>

Look up a state by name.

pub fn transitions_from(&self, state: &str) -> Vec<&MotionTransition>

Return all transitions whose from_state matches state, sorted by descending priority so that callers evaluate highest-priority first.

pub fn default_graph() -> Self

Build the canonical idle / walk / run locomotion graph.

Trait Implementations

impl Default for MotionGraph

fn default() -> Self

Returns the “default value” for a type.
