CUSTOM GAME ENGINES: A Small Study

A couple of weeks ago I played (and finished) A Plague Tale, a game by Asobo Studio. I was really captivated by the game, not only by the beautiful graphics but also by the story and the locations in the game. I decided to investigate a bit about the game tech and I was surprised to see it was developed with a custom engine by a relatively small studio. I know there are some companies using custom engines but it's very difficult to find a detailed market study with that kind of information curated and updated. So this article.

Nowadays lots of companies choose engines like Unreal or Unity for their games (or that's what lot of people think) because d

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

A simple overview of Zig's std.log for Zig v0.12.0 or higher

Logging functionality that supports:

• If a log message should be printed is determined at comptime, meaning zero overhead for unprinted messages (so just leave the code peppered with debug logs, but when it makes sense scope them; so downstream users can filter them out)
• Scoped log messages
• Different log levels per scope
• Overrideable log output (write to file, database, etc.)
• All the standard std.fmt formatting magic

Basic Usage:

" Don't try to be vi compatible
set nocompatible

" Helps force plugins to load correctly when it is turned back on below
filetype off

" TODO: Load plugins here (pathogen or vundle)

" Turn on syntax highlighting

A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
