A fixture definition is used to create a fixture. This class defines an abstract fixture definition. You can reuse fixture definitions safely.

Fields

shape: *const b2Shape

The shape, this must be set. The shape will be cloned, so you can create the shape on the stack.

userData: b2FixtureUserData

Use this to store application specific fixture data.

friction: f32

The friction coefficient, usually in the range [0,1].

restitution: f32

The restitution (elasticity) usually in the range [0,1].

restitutionThreshold: f32

Restitution velocity threshold, usually in m/s. Collisions above this speed have restitution applied (will bounce).

density: f32

The density, usually in kg/m^2.

isSensor: bool

A sensor shape collects contact information but never generates a collision response.

filter: b2Filter

Contact filtering data.

Implementations

impl b2FixtureDef

pub fn new() -> impl New<Output = Self>

The constructor sets the default fixture definition values.

Trait Implementations

impl CopyNew for b2FixtureDef

unsafe fn copy_new( other: &b2FixtureDef, this: Pin<&mut MaybeUninit<b2FixtureDef>> )

Synthesized copy constructor.

impl Drop for b2FixtureDef

fn drop(self: &mut b2FixtureDef)

Synthesized destructor.

impl ExternType for b2FixtureDef

type Id = (b, _2, F, i, x, t, u, r, e, D, e, f)

A type-level representation of the type’s C++ namespace and type name.

impl MakeCppStorage for b2FixtureDef

unsafe fn allocate_uninitialized_cpp_storage() -> *mut b2FixtureDef
