# ofxDeltaTracker
A very lightweight, type-agnostic helper. Returns the change of a tracked value since the last update().
## Motivation
This is useful when converting absolute movement to relative movement,
e.g. when using ofNode.move() instead of ofNode.setPosition();
In this case, using multiple ofxDeltaTracker[s] for one ofNode allows you to
combine multiple relative movements. [see example project]
## Example
See included example project.
### Reference Render
