Struct b2PulleyJoint 

pub struct b2PulleyJoint { /* private fields */ }

The pulley joint is connected to two bodies and two fixed ground points. The pulley supports a ratio such that: length1 + ratio * length2 <= constant Yes, the force transmitted is scaled by the ratio. Warning: the pulley joint can get a bit squirrelly by itself. They often work better when combined with prismatic joints. You should also cover the the anchor points with static shapes to prevent one side from going to zero length.

Trait Implementations

impl AsRef<b2Joint> for b2PulleyJoint

fn as_ref(self: &b2PulleyJoint) -> &b2Joint

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

impl CopyNew for b2PulleyJoint

unsafe fn copy_new( other: &b2PulleyJoint, this: Pin<&mut MaybeUninit<b2PulleyJoint>>, )

Synthesized copy constructor.

impl Drop for b2PulleyJoint

fn drop(self: &mut b2PulleyJoint)

Synthesized destructor.

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 b2PulleyJoint

type Id = (b, _2, P, u, l, l, e, y, J, o, i, n, t)

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

type Kind = Opaque

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

impl MakeCppStorage for b2PulleyJoint

unsafe fn allocate_uninitialized_cpp_storage() -> *mut b2PulleyJoint

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 b2PulleyJoint)

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