pub struct ShapeDefBuilder { /* private fields */ }

Implementations

impl ShapeDefBuilder

pub fn material(self, mat: SurfaceMaterial) -> Self

Set the surface material (friction, restitution, etc.).

pub fn density(self, v: f32) -> Self

Density in kg/m². Affects mass.

pub fn filter(self, f: b2Filter) -> Self

Low-level filter (category/mask/group).

pub fn filter_ex(self, f: Filter) -> Self

High-level filter wrapper.

pub fn enable_custom_filtering(self, flag: bool) -> Self

Enable user-provided filtering callback.

Note: To receive custom filter calls you must also register a world-level callback via World::set_custom_filter_callback.

pub fn sensor(self, flag: bool) -> Self

Mark as sensor (no collision response).

pub fn enable_sensor_events(self, flag: bool) -> Self

Emit sensor begin/end touch events.

pub fn enable_contact_events(self, flag: bool) -> Self

Emit contact begin/end events.

pub fn enable_hit_events(self, flag: bool) -> Self

Emit impact hit events when above threshold.

pub fn enable_pre_solve_events(self, flag: bool) -> Self

Emit pre-solve events (advanced).

Note: To receive pre-solve events you must also register a world-level callback via World::set_pre_solve_callback.

pub fn invoke_contact_creation(self, flag: bool) -> Self

Invoke user callback on contact creation.

pub fn update_body_mass(self, flag: bool) -> Self

Recompute body mass when adding/removing this shape.

pub fn build(self) -> ShapeDef
