Struct libliquidfun_sys::box2d::ffi::b2Transform

#[repr(C)]
pub struct b2Transform {
    pub p: b2Vec2,
    pub q: b2Rot,
}

A transform contains translation and rotation. It is used to represent the position and orientation of rigid frames.

Fields

p: b2Vec2

q: b2Rot

Implementations

impl b2Transform

pub fn SetIdentity(self: Pin<&mut b2Transform>)

Set this to the identity transform.

pub fn Set(self: Pin<&mut b2Transform>, position: &b2Vec2, angle: f32)

Set this based on the position and angle.

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

The default constructor does nothing.

pub fn new1<'a>( position: &'a b2Vec2, rotation: &'a b2Rot ) -> impl New<Output = Self> + 'a

Initialize using a position vector and a rotation.

Trait Implementations

impl CopyNew for b2Transform

unsafe fn copy_new( other: &b2Transform, this: Pin<&mut MaybeUninit<b2Transform>> )

Synthesized copy constructor.

impl Drop for b2Transform

fn drop(self: &mut b2Transform)

Synthesized destructor.

impl ExternType for b2Transform

type Id = (b, _2, T, r, a, n, s, f, o, r, m)

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

type Kind = Trivial

impl MakeCppStorage for b2Transform

unsafe fn allocate_uninitialized_cpp_storage() -> *mut b2Transform
