“Events are evil!” is a common opinion among Unity developers. What are the reasons behind this statement and are interfaces an alternative to events? Example implementation at the bottom. Problems A common source for event bugs are timing issues. For an event to work correctly you have to subscribe before it’s triggered and … Read more
Ever checked an object for null and it didn’t work? Computers do precisely what you tell them to do -> it must be a programming error that bypasses the null check. This is one of the moments where I doubt my sanity as a programmer. What Happened? The C# target object isn’t null … Read more
Problem The CreateAssetMenu attribute is handy if you want a quick way to instantiate scriptable objects. But it falls short when a dynamic name or the initialization of different properties is needed, for example, the generation of a custom ID. Solution The solution is to create the asset yourself. The CreateAssetMenu attribute is only … Read more

Genre: Puzzle Platform: Mobile (android, ios) Artstil: 3D Engine: Unity 3D Year: 2021 Duration: 7 month My Part: Artificial intelligence Pawn movement General gameplay features All of the rules – like shifting the labyrinth and collecting treasures and secrets – … Read more
One constraint of articulation bodies is that they lose their physics state if their hierarchy changes. This behaviour manifests as snapping back to their initial configuration/position. You can find a short overview of the constraints and advantages of articulation bodies here. Problem Changing the active state of the root articulation body is also a … Read more
The system was integrated for industry applications like realistic physic simulations for robotics or the training of neural networks. But it can also be used in games where a high precision physics simulation is needed. For example physics-based puzzles. Some parts of the feature are still buggy or not completely implemented yet. Especially the … Read more
I’m currently playing around with articulation bodies which were introduced in 2020.1. Some parts of the feature are still buggy or not completely implemented yet. Especially the spherical joint seems to exhibit a lot of bugs that crash Unity’s physics system and should be avoided at the moment. Because the feature is so new … Read more
There is a wide range of shaders for visual effects in games. Since the release of Shader Graph, the creation of shaders has become more accessible for non-programmers. This has raised the question: how do you set shader variables if you can’t code? Whenever you want to set/get a shader variable you should do … Read more
I played around with my Arduino starter kit and read a few pages in Making Embedded Systems (more on it here). Now I am ready to blink the built-in LED of my board. My first approach looked like this: #define LED LED_BUILTIN void setup() { SetupLED(); } void loop() { EnableLED(); delay(1000); DisableLED(); delay(1000); } … Read more
I’m really happy to announce that the Museum der Alltagskultur (museum of everyday culture) in Waldenbuch added Craftspeople to their exhibition. It’s a game I contributed to at the Coding da Vinci Hackathon in 2019.
