interpolate
public abstract AnimatableValue interpolate(AnimatableValue result, AnimatableValue to, float interpolation, AnimatableValue accumulation, int multiplier) Performs interpolation to the given value.- Parameters:
result
- the object in which to store the result of the interpolation, or null if a new object should be createdto
- the value this value should be interpolated towards, or null if no actual interpolation should be performedinterpolation
- the interpolation distance, 0 <= interpolation <= 1accumulation
- an accumulation to add to the interpolated valuemultiplier
- an amount the accumulation values should be multiplied by before being added to the interpolated value
