Frequently Asked Questions¶

What is Doriax Engine?¶

Doriax is a free, open-source 2D/3D game engine with an integrated desktop editor. You author scenes visually, script in Lua or C++, and export buildable native projects for desktop, mobile, and web. It is the continuation of Supernova Engine under a new identity, keeping its ECS-based, data-oriented runtime.

How much does it cost? Can I sell my game?¶

Doriax is released under the MIT License — free for personal and commercial use, with no royalties, revenue share, or seat licenses. Bundled third-party libraries keep their own (compatible) open-source licenses. See License & Credits.

Which platforms are supported?¶

Lua or C++ — which should I use?¶

Both target the same runtime API. Lua gives the fastest iteration (no compile step) and is the best starting point; C++ gives native performance for hot paths. Most projects mix them — see Scripting.

Does exporting produce a finished executable?¶

Exporting produces a self-contained, buildable native project (CMake, Gradle, or Xcode depending on the target) with your scenes, assets, scripts, and compiled shaders. You then build it with the platform's standard toolchain — see Exporting a Project and Command-Line Tools for automating this in CI.

Is Doriax production-ready?¶

Doriax is under active development. The downloadable editor builds track the main branch and are not stable releases — expect breaking changes while the engine and documentation are refreshed under the Doriax name. Pin a commit for serious projects and follow the repository for release tags.

How does Doriax differ from Godot, Unity, or Unreal?¶

Doriax aims to be lightweight and code-transparent: a small MIT-licensed C++ runtime with an ECS core, where exporting gives you a native project you fully own and can read, modify, and build yourself. It does not try to match the breadth of larger engines' tooling; it focuses on a compact feature set — 2D, 3D, UI, physics (Box2D / Jolt), audio (SoLoud), particles, terrain, and skeletal animation — with both Lua and C++ as first-class languages.

Where do my old Supernova projects stand?¶

Supernova 0.5.5 was the last release of the legacy engine. The runtime API carried over largely intact (with renames such as SPROPERTY → DPROPERTY and the doriax namespace), but projects should migrate to the Doriax editor workflow. Some internal folders may still mention the previous name during the transition.

Where can I get help or report bugs?¶

• Discord — discord.gg/yXXDyJf3gT for questions and discussion.
• GitHub — github.com/doriaxengine/doriax for issues and contributions.

How can I contribute?¶

Code contributions go through pull requests on GitHub. Documentation lives in its own repository and accepts fixes through the Edit this page links — see the Documentation Guide.
