StepTween class
An interpolation between two integers that floors.
This class specializes the interpolation of Tween<int> to be appropriate for integers by interpolating between the given begin and end values and then using double.floor to return the current integer component, dropping the fractional component.
This results in a value that is never greater than the equivalent value from a linear double interpolation. Compare to IntTween.
See Tween for a discussion on how to use interpolation objects.

Methods
-
lerp(
double t) → int -
Returns the value this variable has at the given animation clock value. [...]
override
-
animate(
Animation< double> parent) → Animation< int> -
Returns a new Animation that is driven by the given animation but that
takes on values determined by this object. [...]
inherited
-
chain(
Animatable< double> parent) → Animatable< int> -
Returns a new Animatable whose value is determined by first evaluating
the given parent and then evaluating this object. [...]
inherited
-
evaluate(
Animation< double> animation) → int -
The current value of this object for the given Animation. [...]
inherited
-
noSuchMethod(

Invoked when a non-existent method or property is accessed. [...]
inherited
-
toString(
) → String -
Returns a string representation of this object.
