Struct b2Shape 

pub struct b2Shape { /* private fields */ }

@file Structures and functions used for computing contact points, distance queries, and TOI queries.

Implementations

impl b2Shape

pub unsafe fn Clone( self: &b2Shape, allocator: *mut b2BlockAllocator, ) -> *mut b2Shape

Clone the concrete shape using the provided allocator.

pub fn GetChildCount(self: &b2Shape) -> c_int

Get the number of child primitives.

pub fn TestPoint(self: &b2Shape, xf: &b2Transform, p: &b2Vec2) -> bool

Test a point for containment in this shape. This only works for convex shapes. @param xf the shape world transform. @param p a point in world coordinates.

pub unsafe fn ComputeDistance( self: &b2Shape, xf: &b2Transform, p: &b2Vec2, distance: *mut f32, normal: *mut b2Vec2, childIndex: c_int, )

Compute the distance from the current shape to the specified point. This only works for convex shapes. @param xf the shape world transform. @param p a point in world coordinates. @param distance returns the distance from the current shape. @param normal returns the direction in which the distance increases.

pub unsafe fn RayCast( self: &b2Shape, output: *mut b2RayCastOutput, input: &b2RayCastInput, transform: &b2Transform, childIndex: c_int, ) -> bool

Cast a ray against a child shape. @param output the ray-cast results. @param input the ray-cast input parameters. @param transform the transform to be applied to the shape. @param childIndex the child shape index

pub unsafe fn ComputeAABB( self: &b2Shape, aabb: *mut b2AABB, xf: &b2Transform, childIndex: c_int, )

Given a transform, compute the associated axis aligned bounding box for a child shape. @param aabb returns the axis aligned box. @param xf the world transform of the shape. @param childIndex the child shape

pub unsafe fn ComputeMass( self: &b2Shape, massData: *mut b2MassData, density: f32, )

Compute the mass properties of this shape using its dimensions and density. The inertia tensor is computed about the local origin. @param massData returns the mass data for this shape. @param density the density in kilograms per meter squared.

impl b2Shape

pub fn GetType(&self) -> b2Shape_Type

Get the type of this shape. You can use this to down cast to the concrete shape. @return the shape type.

Trait Implementations

impl AsRef<b2Shape> for b2ChainShape

fn as_ref(self: &b2ChainShape) -> &b2Shape

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<b2Shape> for b2CircleShape

fn as_ref(self: &b2CircleShape) -> &b2Shape

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<b2Shape> for b2EdgeShape

fn as_ref(self: &b2EdgeShape) -> &b2Shape

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<b2Shape> for b2PolygonShape

fn as_ref(self: &b2PolygonShape) -> &b2Shape

Converts this type into a shared reference of the (usually inferred) input type.

impl Drop for b2Shape

fn drop(self: &mut b2Shape)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl ExternType for b2Shape

type Kind = Opaque

Either cxx::kind::Opaque or cxx::kind::Trivial.

type Id

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

impl MakeCppStorage for b2Shape

unsafe fn allocate_uninitialized_cpp_storage() -> *mut b2Shape

Allocates heap space for this type in C++ and return a pointer to that space, but do not initialize that space (i.e. do not yet call a constructor).

unsafe fn free_uninitialized_cpp_storage(arg0: *mut b2Shape)

Frees a C++ allocation which has not yet had a constructor called.

impl SharedPtrTarget for b2Shape

impl UniquePtrTarget for b2Shape

impl WeakPtrTarget for b2Shape
