A very lightweight, type-agnostic helper. Returns the change of a tracked value since the last update().
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]
See included example project.
ofxPlaylist: ofxDeltaTracker helps greatly in animating ofNode based Objects.
