I’m developing a game in VR using a vive tracker that track’s a rock (dragon egg), the tracking of the object works fine, however I need to make sure the change in each vector is less than a certain amount to make sure they aren’t moving the precious egg too quickly. The code I have posted in the image below just gets the current position, I am unsure of how to save the old position separately as the way I have done it now just gets the current position. I know how to compare it to the old position I just need help getting the old position to save, thanks 
This is being done on the event tick by the way
