Struct libliquidfun_sys::box2d::ffi::b2DistanceJoint

#[repr(C, align(8))]
pub struct b2DistanceJoint { /* private fields */ }

A distance joint constrains two points on two bodies to remain at a fixed distance from each other. You can view this as a massless, rigid rod.

Implementations

impl b2DistanceJoint

pub fn GetLength(self: &b2DistanceJoint) -> f32

Get the rest length

pub fn SetDamping(self: Pin<&mut b2DistanceJoint>, damping: f32)

Set/get linear damping in N*s/m

pub fn GetDamping(self: &b2DistanceJoint) -> f32

pub fn GetAnchorA(self: &b2DistanceJoint) -> b2Vec2

pub fn GetAnchorB(self: &b2DistanceJoint) -> b2Vec2

pub fn GetReactionForce(self: &b2DistanceJoint, inv_dt: f32) -> b2Vec2

Get the reaction force given the inverse time step. Unit is N.

pub fn GetReactionTorque(self: &b2DistanceJoint, inv_dt: f32) -> f32

Get the reaction torque given the inverse time step. Unit is N*m. This is always zero for a distance joint.
