Swapped to use GetValue instead.

@@ -77,6 +77,7 @@ Notes:
 * `Graphics.fillPoints` has renamed the second argument from `autoClose` to `closeShape`. There is also a new third argument `closePath`, which defaults to `true` and automatically closes the path before filling it. The `endIndex` argument is now the fourth argument, instead of the third.
 * Calling `Texture.destroy` will now call `TextureManager.removeKey` to ensure the key is removed from the manager, should you destroy a texture directly, rather than going via `TextureManager.remove`. Fix #4461 (thanks @BigZaphod)
 * `SpriteSheetFromAtlas` now adds in a `__BASE` entry for the Sprite Sheet it creates, keeping it consistent with the other frame parsers (thanks @Cirras)
+* The `from` and `to` properties in the PathFollower Config can now be used to set the span of the follow duration (thanks @kensleebos)
