Struct heron::Velocity [−][src]
Expand description
Component that defines the linear and angular velocity.
It must be inserted on the same entity of a RigidBody
The linear part is in “unit” per second on each axis, represented as a Vec3
. (The unit, being your game unit, be it pixel or anything else)
The angular part is in radians per second around an axis, represented as a Quat
.
Example
fn spawn(mut commands: Commands) { commands.spawn_bundle(todo!("Spawn your sprite/mesh, incl. at least a GlobalTransform")) .insert(CollisionShape::Sphere { radius: 1.0 }) .insert( Velocity::from_linear(Vec3::X * 10.0) .with_angular(AxisAngle::new(Vec3::Z, 0.5 * PI)) ); }
Fields
linear: Vec3
Linear velocity in units-per-second on each axis
angular: AxisAngle
Angular velocity in radians-per-second around an axis
Implementations
Returns a linear velocity from a vector
Returns an angular velocity from a vector
Returns a new version with the given linear velocity
Returns a new version with the given angular velocity
Trait Implementations
pub fn set(
&mut self,
value: Box<dyn Reflect + 'static, Global>
) -> Result<(), Box<dyn Reflect + 'static, Global>>
Returns a serializable value, if serialization is supported. Otherwise None
will be
returned. Read more
Returns a hash of the value (which includes the type) if hashing is supported. Otherwise
None
will be returned. Read more
Returns a “partial equal” comparison result if comparison is supported. Otherwise None
will be returned. Read more

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

to the equivalent element of its superset.
