b1: BodyPartHandle<Handle>,
b2: BodyPartHandle<Handle>,
anchor1: OPoint<N, Const<2>>,
anchor2: OPoint<N, Const<2>>,
length: N,
stiffness: N
) -> Spring<N, Handle>
pub fn new( b1: BodyPartHandle<Handle>, b2: BodyPartHandle<Handle>, anchor1: OPoint<N, Const<2>>, anchor2: OPoint<N, Const<2>>, length: N, stiffness: N ) -> Spring<N, Handle>
Initialize a spring attached to b1
and b2
at the points anchor1
and anchor2
.
Anchors are expressed in the local coordinates of the corresponding bodies.
The spring has a rest length of length
and a stiffness of stiffness
.
sourcepub fn set_anchor_1(&mut self, anchor: OPoint<N, Const<2>>)
pub fn set_anchor_1(&mut self, anchor: OPoint<N, Const<2>>)
Sets the attach point to the first body.
The anchor is expressed in the local coordinatse of the first body.
sourcepub fn set_anchor_2(&mut self, anchor: OPoint<N, Const<2>>)
pub fn set_anchor_2(&mut self, anchor: OPoint<N, Const<2>>)
Sets the attach point to the second body.
The anchor is expressed in the local coordinatse of the second body.
