Struct ConstraintPlugin 

pub struct ConstraintPlugin { /* private fields */ }

A plugin that applies positional constraints to scene nodes.

Runs in the [RuntimePhase::Animate] phase. Spring and damping constraints maintain per-node velocity state internally.

Implementations

impl ConstraintPlugin

pub fn new() -> Self

Create with no constraints.

pub fn add(self, constraint: Constraint) -> Self

Add a constraint (builder style).

pub fn push(&mut self, constraint: Constraint)

Add a constraint.

Trait Implementations

impl Default for ConstraintPlugin

fn default() -> Self

Returns the “default value” for a type.

impl RuntimePlugin for ConstraintPlugin

fn priority(&self) -> i32

Numeric execution priority. Lower values run first. Use the constants in phase as base values and offset within a band if needed.

fn step(&mut self, ctx: &mut RuntimeStepContext<'_>)

Called once per phase execution.

fn type_name(&self) -> &'static str

A stable name for this plugin, used to key per-plugin timing in RuntimeStats. Defaults to the concrete type name; override to disambiguate when several plugins share a type or to give a friendlier label.

fn submit(&mut self, _ctx: &RuntimeStepContext<'_>)

Called once per frame before the step loop, in priority order.

fn collect(&mut self, _ctx: &mut RuntimeStepContext<'_>)

Called once per frame after the step loop, in priority order.

fn on_event(&mut self, _event: &RuntimeEvent, _ctx: &mut RuntimeStepContext<'_>)

Called for each lifecycle event before the step loop.
