Struct PhysicsMaterial 

pub struct PhysicsMaterial {
    pub static_friction: Real,
    pub dynamic_friction: Real,
    pub restitution: Real,
    pub rolling_friction: Real,
}

Physical surface properties.

Fields

static_friction: Real

Coefficient of static friction.

dynamic_friction: Real

Coefficient of dynamic friction.

restitution: Real

Restitution (bounciness), 0 = perfectly inelastic, 1 = perfectly elastic.

rolling_friction: Real

Rolling friction coefficient (for spheres/cylinders).

Implementations

impl PhysicsMaterial

pub fn rubber() -> Self

Create a rubber-like material.

pub fn steel() -> Self

Create a steel-on-steel material.

pub fn ice() -> Self

Create a frictionless ice-like material.

pub fn combine(&self, other: &PhysicsMaterial) -> PhysicsMaterial

Combine two materials using geometric mean for friction and min for restitution (a common convention in game physics).

Trait Implementations

impl Clone for PhysicsMaterial

fn clone(&self) -> PhysicsMaterial

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PhysicsMaterial

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PhysicsMaterial

fn default() -> Self

Returns the “default value” for a type.
