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 |
endValue: Float |
The end value; should be of type |

Float |
A linear interpolation between the start and end values, given the |
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.
