Fading Sprites in Unity 5

This tutorial shows how to extend the class SpriteRenderer  to support intuitive, painless fading transitions. Despite referring to sprites, this approach can be used to easily animate any property of a game object in Unity.

The link for the script used in this tutorial is at the end of the post.

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 problem, but it doesn’t remove it. The main problem is that, despite the name, Unity coroutines are not really executed in parallel with the rest of the game. Unity, by design, is not thread safe. This means that true parallelism is intentionally avoided by the engine, as it could result in race conditions. To solve the problem of the communication between Unity and Arduino, once and for all, we need actual threads.

ShaderGUI: Custom Material Inspectors in Unity 5+

This tutorial explains how to create a custom inspector for your shaders and materials in Unity 5.

material4

This is a tutorial for Unity 5: Unity 4 used MaterialEditor (legacy documentation here) to customise a material’s inspector. That is now deprecated; you should use the new ShaderGUI (documentation here) instead.

An Introduction to Signal Smoothing

Noise is everywhere. Whether you’re sampling accelerometer data for a mobile game or trying to measure the temperature of a room, noise will be there. Even if you could remove all the noise from an input device, you’ll still have a certain degree of uncertainty. If a player has tapped on the screen, where did they really wanted to tap? All these scenarios forces to re-think about how we gather and preprocess data.
