Trait nphysics3d::force_generator::ForceGenerator

pub trait ForceGenerator<N: RealField>: Downcast + Send + Sync {
    fn apply(
        &mut self, 
        params: &IntegrationParameters<N>, 
        bodies: &mut BodySet<N>
    ) -> bool;
}

A persistent force generator.

A force generator applies a force to one or several bodies at each step of the simulation.

Required methods

fn apply(
    &mut self,
    params: &IntegrationParameters<N>,
    bodies: &mut BodySet<N>
) -> bool

Apply forces to some bodies.

Methods

impl<N> dyn ForceGenerator<N> where
    N: Any + 'static,
    N: RealField, 

pub fn is<__T: ForceGenerator<N>>(&self) -> bool

Returns true if the trait object wraps an object of type __T.

pub fn downcast<__T: ForceGenerator<N>>(
    self: Box<Self>
) -> Result<Box<__T>, Box<Self>>

Returns a boxed object from a boxed trait object if the underlying object is of type __T. Returns the original boxed trait if it isn't.

pub fn downcast_ref<__T: ForceGenerator<N>>(&self) -> Option<&__T>

Returns a reference to the object within the trait object if it is of type __T, or None if it isn't.

pub fn downcast_mut<__T: ForceGenerator<N>>(&mut self) -> Option<&mut __T>

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn't.
