Simple Invaders clone using Kenney's Space Shooter redux pack. In this tutorial we will include sprites to make a more complete looking game, but it will still be fairly simple in nature. We have a group of enemies that fire at the player while moving down the screen and a player that can fire back. We use static arrays to create a very simple bullet management system. And use the pythagorean theorem for basic hit detection.
In this tutorial we will be using the following sprites from Kenney's Space Shooter pack. You are free to replace them with other colors or assets from the pack, or replace them with your own images.

Run the following command to get the dependencies for this tutorial. If you are doing these tutorials on a Raspberry Pi, then please read the installation instructions.
For Debian and Ubuntu:
$ sudo apt-get install libgtk-3-dev libegl1-mesa-dev libepoxy-dev libpng-dev git
For Red Hat and Fedora:
$ sudo yum install epel-release $ sudo yum install gtk3-devel mesa-libGL-devel libepoxy-devel libpng-devel git
We will implement our project one step at a time. All of the source code will be displayed for the main.c file each step. Other files will only be displayed when they are created or changed. If you need to check for what the project folder looks like at any given step, you can follow the Github links on each page to view the file layout.
If you have a specific coding style approach then feel free to use that. If you are new to programming, then this guide recomends separating each step into it's own folder, copying the previous folder each time. That will allow you to go back and double-check a working version in case something breaks.
