Baue dein C#-Fundament auf — Syntax, Datentypen, Kontrollstrukturen, Schleifen, Arrays und Methoden. Der Ausgangspunkt des Unity-Tracks, der dir die Sprachkompetenz vermittelt, die du benötigst, bevor du mit der Engine arbeitest.


In diesem Abschnitt erhalten wir eine Einführung in C#. Darüber hinaus lernen wir einige grundlegende Elemente der C#-Sprache kennen.
