Short Note

Before we jump in

For our 2D apps I may want to use sprites to start with, so I wrote a little project for sprite sheet atlases and an app that uses it as an example. We will use this sprite sheet description atlas to give the app info about our sprite sheet without needing to hard code all the positions of each sprite.

The code is MIT so you can use it as you please as long as you read the licence and agree to it. It is placed there for your 'learning' and you may choose to make changes to it as you please though forking it and submitting improvements will be welcome should you choose. You may need to send a message to me to get it working correctly for you to make submissions.

The sprite sheet image uses alpha-color which means the image file doesn’t use an aplha channel but simply a color like purple to be the alpha channel. So I wrote ~ after consulting AI ~ a few extra functions in the go-rommy example that copy the image and repace all the colored pixels to alpha. I could have used a mask ~ I’m sure its pretty much the same.

Go & Games Series

GO & RAYLIB ~ Get Setup

POST UPDATED : 2025-11-21

Intro

This tutorial we will setup your Raylib-go dev environment and create a project which will produce a blank window. In a Windows 11 environment. The setup on Linux and Mac are well described on the raylib site. Windows requires extra effort to set up a C compiler but has a very simple method of using the raylib-dll. We will use this method to get you started as quickly as possible.

Requirements

You need Go installed ~ the newest version is often a good idea, then stick with that untill you are comfortable. You can get it from GO.DEV downloads
Git from Git-scm.com/downloads
A text editor or an IDE. VSCode, Goland, Notepad

What experience has shown me

Git is essential. Yes for version control, BUT mostly helps you NOT to loose all your code.
Writing Tests is more important than you think and does save time. Weirdly and automatically you write manageable code.
Learning a new computer language is not difficult but not simple either. (similarities trip you up - often)
