hello,,, i have used and try to modify this code > https://developer.vuforia.com/resources/dev-guide/unity-drag-ar-object-screen-your-finger
and it's successfully move cube object. but i have some case that sometimes my object cannot be moved on y axis(upward and downward) or z axis(backward and forward).
i try to make y axis to be zero but it's not working... i just can move my object to right and left,,, but not to backward and forward.
then i've tried to add rigidbody and checked y axis on Freeze Position but i still can move my object upward and downward
thanks for your help
