Hi everyone.
In my eclipe project I have a cub who browse a path like this code:
It’s work with a chase camera but i want to change the chase camera by a cameraNode, and it don’t work.
whene the cube browse the path the cameranode dont move.
What should I do?
I haven’t find an equivalent for " chaser.registerWithInput(inputManager); "
thants.
Your code looks fine from here. (since we can’t see it)

}in MotionEvent you have to use setDirectionType(MotionEvent.LookAt) and then use the setLookAt method.
Note that this method use the REFERENCE of the vector you pass in so any modification to the vector will make the spatial on the track face it.
hello
I haven’t success to make it work like that but I success by adding a MotionEvent like this code
motionControlcam = new MotionEvent(camNode,path);
motionControlcam.setDirectionType(MotionEvent.Direction.PathAndRotation);
motionControlcam.setInitialDuration(10f);
motionControlcam.setSpeed(2f);
thank you
