I created a scene in the editor based on what I envisioned, but it was absolutely impossible to run on Oculus Quest. This article describes various tricks I have used to bring it to Quest without too much sacrifice.
Using vectors in place of hashtables – not as dumb as it seems
Vector can find elements in linear time, hashtable in constant time. That’s a pretty elementary part of computer science. However, better complexity does not always mean it’s faster.
Super compact serialisation of C++ classes
How about defining the variable, initialising it and writing code for serialisation and deserialisation on a single line of code?
Generic self-registering factory – no more need to write factories
It’s somewhat annoying that a factory needs to depend on all classes that inherit from the common interface. This issue can be avoided using a self-registering factory.
Writing a JSON library in 2 hours in C++
C++ has a bad reputation for long times needed for development. However, as this task has shown, it does not deserve this reputation.
Serialisation of C++ classes with very little code
Serialisation into human readable formats tends to be a tedious task in programming languages without a lot of reflection. Here is a trick to make it far less repetitive in C++.

Copy-paste drive development and other innovative techniques for speedy programming
An ironic advice about programming… or better to say, an advice how to get fired from your job and then assaulted by me
