To start off, let me explain what I am trying to accomplish. I want to be able to choose a location of a node or other object and any transformation, and have the object move there at a variable speed. There is a method in Unity 3d called Larp or Lerp which does this and I was wondering if there was a way to do this in jme3. Essentially I want to choose a destination, which has rotation, translation, maybe scale factor, and have the object transition to it at a speed that I enter. How can this be achieved?
Just move the object decoupled from the framerate each frame (speedVector *tpf, see the hello tutorials). Or use math!
