SS23 – VVVV – 01 – Creating an App from Scratch

May 4th 2023 6-9 PM (CET) / In English Language / Online via Zoom

We’ll patch a small App from zero to .exe. Our widget library of choice will be VL.ImGui. If you were ever scared about the Reactive-Observable-Woodoo, then Channels are your friends: so easy to set up, notify and react to whatever a user wants from your app. We’ll use them to bind the UI and the App’s brains.

What you will learn

  • How fast it is to click together a UI by using VL.ImGui library
  • How to wire that UI to an App’s brain by using Channels
  • Update, Load and Save an app’s state / its settings
  • Enrich a UI with custom 2D graphics (rendered with Skia)
  • Combine the UI with 3D graphics (rendered with Stride)
  • Tips & tricks about using VL.ImGui

Who is it for?

Everybody who has a quick and useful app in mind, that is just waiting to be patched and exported.

Presumed knowledge

A basic understanding of VLs language methodologies (pads, regions, spreads) is needed!


  • Windows Computer
  • A 3 button mouse
  • We recommend you to use an external monitor connected to your laptop or PC, this would help you to follow the instructors screen while you patch along on your own device.
  • The instructor might ask you to share your screen, therefore it is recommended to remove personal data from your desktop.
