pub end: Quat,
}
Expand description
A lens to manipulate the rotation
field of a Transform
component.
This lens interpolates the rotation
field of a Transform
component
from a start
value to an end
value using the spherical linear
interpolation provided by Quat::slerp()
. This means the rotation always
uses the shortest path from start
to end
. In particular, this means it
cannot make entities do a full 360 degrees turn. Instead use
TransformRotateXLens
and similar to interpolate the rotation angle
around a given axis.
See the top-level lens
module documentation for a comparison of rotation
lenses.
Fields§
§start: Quat
Start value of the rotation.
end: Quat
End value of the rotation.

fn lerp(&mut self, target: &mut Transform, ratio: f32)
Perform a linear interpolation (lerp) over the subset of fields of a
component or asset the lens focuses on, based on the linear ratio
ratio
. The target
component or asset is mutated in place. The
implementation decides which fields are interpolated, and performs
the animation in-place, overwriting the target.source§impl PartialEq<TransformRotationLens> for TransformRotationLens
