CUSTOM GAME ENGINES: A Small Study

WARNING: Article moved to separate repo to allow users contributions: https://github.com/raysan5/custom_game_engines

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](https:

Problem

I have a notebook connected to a port replicator. I want to use the build-in speakers and microfone and not the external ones. If I boot my notebook in my port replicator Ubuntu changes the devices to external.

Solution

Find your internal speaker

Some notes on getting Debian 10 (stable) installed and running on the Beelink U57 Mini PC with Intel Core i5-5257u Processor.

Install Debian

Create a bootable USB Flash drive of the Debian 10 netinst ISO using Etcher.

Download ISO from Debian: https://www.debian.org/distrib/netinst
Flash to SD Card using Balena Etcher https://www.balena.io/etcher/
Connect ethernet cable to Beelink

Note: The firmware needed to use the Beelink's onboard Intel Wifi is proprietary, and is not included with the default install of Debian. If you don't have the option of a wired LAN connection you can use an "unofficial" Debian CD image, that includes the proprietary (non-free) firmware. (https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/) See the below section on installing the firmware later on.

Immediately after startup press the Del key to enter the BIOS.

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)

Learn Go in ~5mins

This is inspired by A half-hour to learn Rust and Zig in 30 minutes.

Basics

Your first Go program as a classical "Hello World" is pretty simple:

First we create a workspace for our project:

	# Put this function to your .bashrc file.
	# Usage: mv oldfilename
	# If you call mv without the second parameter it will prompt you to edit the filename on command line.
	# Original mv is called when it's called with more than one argument.
	# It's useful when you want to change just a few letters in a long name.
	#
	# Also see:
	# - imv from renameutils
	# - Ctrl-W Ctrl-Y Ctrl-Y (cut last word, paste, paste)
