On October 13, 2025, the Unity Crash Course started for the third time at the University of Konstanz. Unity is a development environment that makes creating Virtual Reality (VR) games and applications easier. For many VR courses, completing the Crash Course is a prerequisite. For one week, students learned the basics of Unity and VR development implementing a Fruit Ninja Clone in a live tutorial format. The course was supported by Daniel Fink and teaching assistants Paulina Leutloff and Felix Kalchschmid.
On Monday, the course began with an introduction by Oliver Deussen (A01), Karsten Klein (A09), and Tiare Feuchtner (C07). After that, the students received their laptops and followed a live tutorial led by Carlos Pinheiro de Sousa to learn the Unity interface. They learned how to create game objects, materials, and prefabs. Using these skills, they built a small ruin that later served as the environment for a Fruit Ninja–style game.
On Tuesday, Abdelrahman Zaky (C07) taught them scripting. They created a script where they instantiated fruits and added velocity to make them fly towards a player.
On Wednesday, they completed this coding part, enabling them to slice the flying fruits with the mouse. Afterwards, the participants received an introduction to VR and VR interactions from Tiare Feuchtner (C07). They were then given VR headsets and could try out different VR games to get familiar with various interaction techniques in VR.
On Thursday, they started with VR development. Wilhelm Kerle-Malcharek (D04) taught them how to use the OpenXR plugin. They learned how to make objects interactable in VR, the basics of user interfaces, and movement methods such as teleportation.
Finally, on Friday, their knowledge was put to the test — they had to combine everything they had learned during the week. Based on a set of tasks, they created their own VR Fruit Ninja game, with support available whenever needed. Thirteen students successfully completed the course and are now ready for Unity VR development.
