ProgramTests.cs

Bouw je C#-basis — syntaxis, datatypen, controleflow, lussen, arrays en methoden. Het startpunt van het Unity-traject dat je de taalvaardigheid geeft die je nodig hebt voordat je met de engine aan de slag gaat.


In deze sectie krijgen we een introductie tot C#. Daarnaast leren we enkele basiselementen van de C#-taal.
