This is exactly what I was looking for. Thank you for taking the time!
As far as movement, I am moving a pawn with mouse clicks (Get Hit Result Under Cursor by Channel). Ultimately, this is intended for tablet and touch control. The back story is that I am making an activity–not so much a game–for someone who is cognitively impaired. My aim is to distill the UI to its simplest form. In other words, see the thing, touch the thing. I made the mistake of turning on physics simulation and gravity. Also I needed to customize the collision so the line trace under the cursor stopped reading the leaves. That was what caused the jitter. Now I’m working on getting the pawn (rake) to orient to the direction of the movement. Thanks again!
