vInterpTo - this will make it less snappy and allow it to glide much more smoother along the spline. It’s used to smooth out data over time. Many variations and applications of this method exist.
Better, far from perfect, though.
While it may seem like it at first, I don’t think this is a good overall method for this. I’d just rotate the widget towards the player. You wouldn’t even need a spline. A spline would be a must if there’s a complex path shape we must follow.
edit: I must admit the accuracy of what the Find Location Close to World Location actually returns leaves a LOT to be desired. I even cranked up the Reparam Steps of the spline segment and it still acts goofy, unable to pinpoint the world loc. And adding extra points make it worse…
