    pub angvel: f32,
}

linvel: Matrix<f32, Const<2>, Const<1>, ArrayStorage<f32, 2, 1>>

The linear velocity of the rigid-body.

angvel: f32

The angular velocity of the rigid-body.

Implementations

impl RigidBodyVelocity

pub fn new( linvel: Matrix<f32, Const<2>, Const<1>, ArrayStorage<f32, 2, 1>>, angvel: f32, ) -> RigidBodyVelocity

Create a new rigid-body velocity component.

pub fn from_slice(slice: &[f32]) -> RigidBodyVelocity

Converts a slice to a rigid-body velocity.

The slice must contain at least 3 elements: the slice[0..2] contains the linear velocity and the slice[2] contains the angular velocity.

pub fn zero() -> RigidBodyVelocity

Velocities set to zero.

pub fn as_slice(&self) -> &[f32]

This velocity seen as a slice.

The linear part is stored first.

pub fn as_mut_slice(&mut self) -> &mut [f32]

This velocity seen as a mutable slice.

The linear part is stored first.

pub fn as_vector( &self, ) -> &Matrix<f32, Const<3>, Const<1>, ArrayStorage<f32, 3, 1>>

This velocity seen as a vector.

The linear part is stored first.

pub fn as_vector_mut( &mut self, ) -> &mut Matrix<f32, Const<3>, Const<1>, ArrayStorage<f32, 3, 1>>

This velocity seen as a mutable vector.

The linear part is stored first.

pub fn transformed(self, rotation: &Unit<Complex<f32>>) -> RigidBodyVelocity

Return self rotated by rotation.

pub fn pseudo_kinetic_energy(&self) -> f32

The approximate kinetic energy of this rigid-body.

This approximation does not take the rigid-body’s mass and angular inertia into account.

pub fn apply_damping( &self, dt: f32, damping: &RigidBodyDamping, ) -> RigidBodyVelocity

Returns the update velocities after applying the given damping.

pub fn velocity_at_point( &self, point: &OPoint<f32, Const<2>>, world_com: &OPoint<f32, Const<2>>, ) -> Matrix<f32, Const<2>, Const<1>, ArrayStorage<f32, 2, 1>>

The velocity of the given world-space point on this rigid-body.

pub fn integrate( &self, dt: f32, init_pos: &Isometry<f32, Unit<Complex<f32>>, 2>, local_com: &OPoint<f32, Const<2>>, ) -> Isometry<f32, Unit<Complex<f32>>, 2>

Integrate the velocities in self to compute obtain new positions when moving from the given inital position init_pos.

pub fn is_zero(&self) -> bool

Are these velocities exactly equal to zero?

pub fn kinetic_energy(&self, rb_mprops: &RigidBodyMassProps) -> f32

The kinetic energy of this rigid-body.

pub fn apply_impulse( &mut self, rb_mprops: &RigidBodyMassProps, impulse: Matrix<f32, Const<2>, Const<1>, ArrayStorage<f32, 2, 1>>, )

Applies an impulse at the center-of-mass of this rigid-body. The impulse is applied right away, changing the linear velocity. This does nothing on non-dynamic bodies.

pub fn apply_torque_impulse( &mut self, rb_mprops: &RigidBodyMassProps, torque_impulse: f32, )

Applies an angular impulse at the center-of-mass of this rigid-body. The impulse is applied right away, changing the angular velocity. This does nothing on non-dynamic bodies.

pub fn apply_impulse_at_point( &mut self, rb_mprops: &RigidBodyMassProps, impulse: Matrix<f32, Const<2>, Const<1>, ArrayStorage<f32, 2, 1>>, point: OPoint<f32, Const<2>>, )

Applies an impulse at the given world-space point of this rigid-body. The impulse is applied right away, changing the linear and/or angular velocities. This does nothing on non-dynamic bodies.

Trait Implementations

impl Add for RigidBodyVelocity

type Output = RigidBodyVelocity

The resulting type after applying the + operator.
