FAQ

The original Avoyd we now call Avoyd 1999 (you can download it free from our site), Quite's haunting zeo-x-s demo, Rez (Area 4 in particular), FPSs we've liked to play like Unreal Tournament, Descent, and much more.

Minimum Requirements

Avoyd runs on our in-house voxel game engine written in C++ using OpenGL, and Vulkan for the GPU renderer. This is partly why the download size is small. The engine is developed by Doug Binks and Juliette Foucaut.

To follow our progress with the game technology, see the Game Tech topic on our devlog, our public posts on Patreon and follow @dougbinks and @juulcat on Mastodon.

We open source parts of our engine:

• Runtime Compiled C++ for rapid iteration

• enkiTS, my lightweight multithreading task scheduler - further information can be found under our devlog's enkiTS topic

• enkiMI, our Minecraft Importer library

• IconFontCppHeaders, our script to generate Font Awesome icon fonts header files for the GUI

• imgui_markdown, markdown for Dear ImGui

We use third-party open-sourced software listed below. Many thanks to the authors and maintainers of these libraries.

• OpenGL for Graphics

• GLFW for platform independent OpenGL Window & Input handling

• GLEW OpenGL Extension Wrangler Library

• OpenAL Soft for Audio

• RakNet for Networking (using just the low level network code)

• NanoVG for HUD elements

• Dear ImGui for the GUI

• ImGuizmo for 3D manipulation in the Voxel Editor

• LZ4 for compression

• A modified version of SJSON for settings files

• A modified version of the Ray Slope Intersection source from the article on Fast Ray/AABB Overlap Tests.

• Microprofile for real-time profiling - see enkiTSExamples for a sample usage.

• jo_gif GIF writer

• open game tools for reading MagicaVoxel .vox files

• libcurl

• robin-hood-hashing for hash map

• MurmurHash3 hash functions

• xxHash hash functions

• uint C# xxHash, we derived our C++ uint32_t xxHash implementation from this C# example

• dbgtools platform independent debug functions

• stb single-file libraries for C/C++

• TinyEXR for OpenEXR images support

Download the Avoyd release from our store or, if you are logged in and own Avoyd, from your Library.

(1* with the occasional longer breaks due to larger features, and as we are only two developers.)

If you would like more details see the devlog post about the Beta release stream.

We plan to carry on crafting Avoyd over time, evolving and updating it continuously.

We started working on Avoyd in 1999, selling the game as shareware. It was, to our knowledge, the first game with an entirely editable environment (destruction and building). After a 10 year break we restarted development in 2012, rewriting the game engine from scratch and evolving the concept to take advantage of technological advances.

Whilst the game is unfinished, the voxel editor is already very usable. To reflect this we sell Avoyd at a reduced price. You can download the full feature demo of Avoyd on our website, with the Voxel Editor component and the game prototypes Wander and Skirmish available to use.

You'll find detailed information about each release of Avoyd in the changelog and our News forum. We also publish an email newsletter.
