GPU Sorting
—
This article introduces the concept of parallel sorting, discussing the theory and implementation of a shader that can sort pixels. You can read the full series here: You can find a link to download the Unity source code at the end of this tutorial.

Tentacle Suckers Shader
—
Following the unexpected success of the tutorial on Inverse Kinematics for Tentacles, I have decided to share the shader that I used to make them so realistic. If you are not familiar with shaders, fear not. This tutorial will be target at beginners, and you’ll only need a basic understanding of how Unity works. A…

Iterators in C#: yield, IEnumerable & IEnumerator
—
Iterating over lists in C# is often done using for loops. This tutorial shows how the foreach construct can be coupled with the yield statement to create more elegant and safe code.

Asynchronous Serial Communication
—
In a previous post, How To Integrate Arduino With Unity, we have shown how data can be sent and received through the serial port. The main problem encountered was dealing with the latency and the delays that communicating across different devices introduces. The solution proposed in that tutorial used a coroutine; decoupling the device communication from the game logic attenuates the…

Arrays & Shaders in Unity 5.4+
—
This post shows how to use arrays and shaders in Unity 5.4. Back in January I already covered this topic in an article called Arrays & shaders: Heatmaps in Unity. My original approach exposed an undocumented feature that allowed to pass arrays to shaders. Since then, Unity 5.4 has introduced proper support in its API. This tutorial replaces…

Arrays & shaders: heatmaps in Unity
—
This tutorial explains how to pass arrays to shaders in Unity. This feature has been present for a long time, but is mostly undocumented. Unity 5.4.0 Beta 1 will introduce a proper API to pass arrays to shaders; this technique however will work with any previous version. If you are using Unity 5.4+, please refer to the Arrays & Shaders…
