pub fn heightfield(heights: Vec<Real>, scale: Vec2) -> Self

Initializes a collider builder with a heightfield shape defined by its set of height and a scale factor along each coordinate axis.

pub fn from_shared_shape(shape: SharedShape) -> Self

Make a collider from a Rapier or Parry shape.

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

Sets whether or not the collider built by this builder is a sensor.

pub fn friction(self, friction: Real) -> Self

Sets the friction coefficient of the collider this builder will build.

pub fn friction_combine_rule(self, rule: CoefficientCombineRule) -> Self

Sets the rule to be used to combine two friction coefficients in a contact.

Sets the restitution coefficient of the collider this builder will build.

pub fn restitution_combine_rule(self, rule: CoefficientCombineRule) -> Self

Sets the rule to be used to combine two restitution coefficients in a contact.

pub fn density(self, density: Real) -> Self

Sets the uniform density of the collider this builder will build.

This will be overridden by a call to Self::mass or Self::mass_properties so it only makes sense to call either Self::density or Self::mass or Self::mass_properties.

The mass and angular inertia of this collider will be computed automatically based on its shape.

pub fn mass(self, mass: Real) -> Self

Sets the mass of the collider this builder will build.

This will be overridden by a call to Self::density or Self::mass_properties so it only makes sense to call either Self::density or Self::mass or Self::mass_properties.

The angular inertia of this collider will be computed automatically based on its shape and this mass value.

pub fn enabled(self, enabled: bool) -> Self

Enable or disable the collider after its creation.
