Lets talk to each other. talking between classes with UI

this is just a quickie example made. i had some help from a forum post i asked a day or so ago, so have made the findings available.
all it is, is a white rectangle moving on screen, with the help of 2 ofxGui sliders. the rectangle is stored in its own separate class, with the ofxGui in the main ofApp.
it uses ofParameter/ofParameterGroup plus ofxGui.

ive commented as best i could think, i have dyslexia so could be a little bit ‘hmmm’ to read :wink:
but it should be clear. its the most basic thing i could think of as an example :wink: but useful for others :wink:
