StepTween class

An interpolation between two integers that floors.

This class specializes the interpolation of Tween to be appropriate for integers by interpolating between the given begin and end values and then using int.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.

lerp(double t) int
Returns the value this variable has at the given animation clock value. [...]
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.
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.
evaluate(Animation<double> animation) int
Returns the interpolated value for the current value of the given animation. [...]
