FloatEvaluator

class FloatEvaluator : TypeEvaluator


This evaluator can be used to perform type interpolation between float values.

Summary

Public functions

Float
evaluate(fraction: Float, startValue: Float, endValue: Float)

This function returns the result of linearly interpolating the start and end values, with fraction representing the proportion between the start and end values.

java-static FloatEvaluator

Returns an instance of FloatEvaluator that may be used in setEvaluator.

Public functions

evaluate

fun evaluate(fraction: Float, startValue: Float, endValue: Float): Float

This function returns the result of linearly interpolating the start and end values, with fraction representing the proportion between the start and end values. The calculation is a simple parametric calculation: result = x0 + t * (v1 - v0), where x0 is startValue, x1 is endValue, and t is fraction.

Parameters
fraction: Float

The fraction from the starting to the ending values

startValue: Float

The start value; should be of type float or Float

endValue: Float

The end value; should be of type float or Float

Returns
Float

A linear interpolation between the start and end values, given the fraction parameter.

getInstance

java-static fun getInstance(): FloatEvaluator

Returns an instance of FloatEvaluator that may be used in setEvaluator. The same instance may be used in multiple Animators because it holds no state.

Returns
FloatEvaluator

An instance of FloatEvaluator.
