[−][src]Struct nphysics2d::force_generator::Spring
Generator of a force proportional to the distance separating two bodies.
Methods
impl<N: RealField, Handle: BodyHandle> Spring<N, Handle>
[src]
pub fn new(
b1: BodyPartHandle<Handle>,
b2: BodyPartHandle<Handle>,
anchor1: Point<N>,
anchor2: Point<N>,
length: N,
stiffness: N
) -> Self
[src]
b1: BodyPartHandle<Handle>,
b2: BodyPartHandle<Handle>,
anchor1: Point<N>,
anchor2: Point<N>,
length: N,
stiffness: N
) -> Self
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
.
pub fn set_anchor_1(&mut self, anchor: Point<N>)
[src]
Sets the attach point to the first body.
The anchor is expressed in the local coordinatse of the first body.
pub fn set_anchor_2(&mut self, anchor: Point<N>)
[src]
Sets the attach point to the second body.
The anchor is expressed in the local coordinatse of the second body.
