Hi,
I’m moving an actor (skeletal mesh) along a pline using a Timeline.
How can I get the speed of the mesh ? The mesh does NOT use physics and is NOT a pawn, so I can’t “get linear velocity”. I’ve tried to get the world location difference between old position (frame f) and the new one (frame f+1) but can’t afford to something coherent. Could someone post a screenshot of a working Blueprint setup ?
This is why I have now (and this returns me a VectorLength of 0).
