How to make continuous MotionPath

I’ve build a MotionPath for my Spatial by adding waypoints. It is working fine when I do something like this

path.addWayPoint(new Vector3f(0, 0, 0));
path.addWayPoint(new Vector3f(2, 0, 0));
path.addWayPoint(new Vector3f(4, 0, 0));
path.addWayPoint(new Vector3f(6, 0, 0));

I wanted to move it dynamicly by putting waypoints in method like this

public void moveSpatial(float x) {
    Vector3f currentTranslation = spatial.getLocalTranslation();
    path.addWayPoint(currentTranslation.x, 0, 0);
    path.addWayPoint(currentTranslation.x + x, 0, 0);

and in simpleUpdate method I’ve added

spatial.setLocalTranslation(new Vector3f(newX, 0, 0);


float newX = currentTranslation.x + x;

now, the animation (smooth move) is working BUT every time when I invoke moveSpatial method the spatial first goes to starting point Vector3f(0, 0, 0) and then he is moving by waypoints. the (0, 0, 0) is position set for spatial when I start the application. I would like to make the movement from the last position where spatial ended his movement. How to do this ?

MotionPaths are for premade animations like cinematics, if you want to move your spatials on arbitrary paths in-game you should really look into simply moving them yourself.
