    pub j_id: usize,
    pub wj_id: usize,
    pub ndofs: usize,

A unilateral (inequality) constraint between a dynamic body and one without any degrees of freedom.


impulse: N

The impulse applied by the constraint.

r: N

The scaling parameter used by the SOR-prox method.

rhs: N

The target velocity change this constraint must apply.

impulse_id: Id

The index of the impulse used for its storage in an impuse cache.

assembly_id: usize

The assembly index of the dynamic body.

j_id: usize

Index of the first entry of the jacobian of the constraint affecting the dynamic body.

wj_id: usize

Index of the first entry of the constraint jacobian multiplied by the inverse mass of the dynamic body.

ndofs: usize

Number of degree of freedom of the dynamic body.
