Car Race
Gruppenarbeit: Dominik Stucky, Diego Martinez "Das OSC Protokoll (Open-Sound-Control) erlaubt es, auf eine einfache Art und Weise Daten über ein Netzwerk zu schicken". Dies haben wir gemeinsam in einer ersten kleinen Übung in der Klasse ausprobiert. Danach galt es eine sinnvolle Anwendung für dieses Protokoll zu finden. Wir haben uns für ein Game entschieden, bei dem vorerst mal zwei Personen jeweils ein Auto steuern. Als Steuerelement haben wir der Einfachheit halber Potentiometer verwendet und jeweils ein Arduino an einen Rechner angeschlossen. Mit OSC haben wird dann den analogen Input am zweiten Rechners zum Hauptrechner übermittelt. Die Oberfläche haben wir dann vollständig in Processing umgesetzt. Es gibt eine Kollisionsabfrage zwischen den beiden Autos, Fahrbahnrand, sowie zwischen Hindernissen und den Autos.
