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.

fn apply(

Blanket Implementations
Mutably borrows from an owned value. Read more
Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait. Read more
Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be
further downcast into Rc<ConcreteType> where ConcreteType implements Trait. Read more
Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s. Read more
Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s. Read more

The inverse inclusion map: attempts to construct self from the equivalent element of its
superset. Read more
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.
The inclusion map: converts self to the equivalent element of its superset.
