Issue #62 - AR/VR, Gestures, 2020.2 and more!

This week runs the gamut from 2D up to AR/VR experiences. Whatever you are working on, hopefully you can find something useful. Enjoy!

The Power of Extension Methods - Changing code. It’s a minefield. If you’re attempting to abide by the laws of the Open Closed Principle, we want to avoid changing previously written code wherever possible, in favour of extending our codebase with new functionality. This allows us to hopefully minimise the number of bugs we inadvertently introduce to our codebase.

Rules for a Future-Proof 2D Render Order - Once you start working on a 2D game, the question of how to set up a proper render order will come up very early on. Render order, at least in the way I will be using the term, determines which parts of your 2D game get rendered (drawn, displayed, shown) in front of (i.e. later than) other parts.

Creating a Replay System in Unity - A replay system is a great way to let players relive their best (or worst) moments of gameplay, improve their strategy, and more! In this tutorial, you’ll build a simple state-based replay system and learn about how replay systems work.

Toon Lighting Basics - I thought it would be a good idea to write up some of the basics of Toon Lighting for anybody that isn't familiar with it.

Graphics.DrawProcedural - The last tutorial was about compute shader basics, how to generate values, read them back to the cpu and use them. One critical aspect in all that is that copying data from the cpu to the gpu (from the ram to the vram) or back takes some time, so wouldn’t it be neat if there was a way to just render the data directly from the GPU without copying it around? Thats where Graphics.DrawProcedural and similar methods come into play, they allow us to do exactly that.

Training a performant object detection ML model on synthetic data using Unity Perception tools - Supervised machine learning (ML) has revolutionized artificial intelligence and has led to the creation of numerous innovative products. However, with supervised machine learning, there is always a need for larger and more complex datasets, and collecting these datasets is costly. How can you be sure of the label quality? How do you ensure that the data is representative of production data? An exciting new solution to this problem, particularly for object detection tasks, is to generate a massive synthetic dataset. Synthetic data alleviates the challenge of acquiring the large labeled datasets needed to train machine learning models.
