Struct nphysics3d::force_generator::Spring [−][src]
pub struct Spring<N: RealField + Copy, Handle: BodyHandle> { /* fields omitted */ }
Expand description
Generator of a force proportional to the distance separating two bodies.
Implementations
pub fn new(
b1: BodyPartHandle<Handle>,
b2: BodyPartHandle<Handle>,
anchor1: Point<N>,
anchor2: Point<N>,
length: N,
stiffness: N
) -> Self
pub fn new(
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
.
Sets the attach point to the first body.
The anchor is expressed in the local coordinatse of the first body.
Sets the attach point to the second body.
The anchor is expressed in the local coordinatse of the second body.

Checks if self
is actually part of its subset T
(and can be converted to it).
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.

to the equivalent element of its superset.
