Semantic classes that wrap around low-level concepts and provides often used functionality.

Sattribute

This class functions as a smarter attribute (though originally the name was short for Super-attribute).

• keeps a history of previous values
• provides events to hook into to (beforeChange, afterChange, beforeSet, afterSet).

Quick Start

class Game {
	public: // constructor
		Game(){
			score.set(0);
			ofAddListener(score.afterChange, this, &Game::onScoreChange);
		}

	public: // (s)attributes
		Sattribute<int> score;

	private: // callbacks
		void onScoreChange(Sattribute<int> &sattr){
			int points = attr.get() - attr.prev();
			ofLog() << "You just scored " << ofToString(points) << " point(s)."
		}
};
