As of ~April 2020, I stopped working on this project for several reasons.

The way I created this was quite "over done" to the point it got hard to work out how to add new features, perhaps due to trying to be an engine rather than a game. However, I am interested in one day revisiting this concept, however perhaps in a different repository rather than this one.

Open Builder

Open source Minecraft-like voxel sandbox game with multiplayer support.

More information about the project can be found in the Open Builder Wiki

This was made mostly for a YouTube series which can be found here: Lets Code A Multiplayer Voxel Game

Building and Running

Windows (Visual Studio)

The easiest way to build is to use vcpkg and install dependencies through this:

vcpkg install sfml
vcpkg install imgui
vcpkg install glm
vcpkg integrate install

Then open the Visual Studio project file to build and run.

Linux

Pre-requisites

Install Vcpkg and other required packages using your distribution's package manager:

git clone https://github.com/microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh

# These are required to build some packages
sudo apt install cmake make autoconf libtool pkg-config

# The following are required for SFML
sudo apt install libx11-dev xorg-dev freeglut3-dev libudev-dev

Ensure paths are set correctly:

export VCPKG_ROOT=/path/to/vcpkg
export PATH=$VCPKG_ROOT:$PATH

RECOMMENDED: Add the above lines to your .bashrc or .zshrc file:

echo 'export VCPKG_ROOT=/path/to/vcpkg' >> ~/.bashrc
echo 'export PATH=$VCPKG_ROOT:$PATH' >> ~/.bashrc

Build and Run

To build, at the root of the project:

vcpkg install # First time only
sh scripts/build.sh

To run, at the root of the project:

sh scripts/run.sh

To build and run in release mode, simply add the release suffix:

sh scripts/build.sh release
sh scripts/run.sh release

History

Originally, this was going to be a Zombie game, but I got very bored of that very quickly, and so changed the project to be a voxel game instead.

As a result of this, the code was created for the zombie game, so when I decided to switch over, the code got messy very quickly.

To combat this, I did a massive refactor in just over 2 weeks, re-creating large parts of the project.
