Dagon uses modern graphics techniques and so requires a fairly powerful graphics card to run. Turing-based NVIDIA cards are recommended (although ray tracing support is not required). The engine is only desktop, support for mobile and web platforms is not planned. Dagon works on Windows and Linux.

Download

Latest source tarball can be downloaded from GitHub releases page.

You can also add Dagon as a dependency to your DUB project:

Getting Started

Assuming you have installed the D language toolchain, the recommended way to start using Dagon is to create a game template with "dub init". Run the following in an empty directory:

By running a template application you should see a sample scene with a plane and a cube. You can then modify the generated dub.json file to suit your needs.

Installing Runtime Dependencies

Dagon depends on the following shared libraries:

• SDL 2.0.14
• Freetype 2.8.1 (optional)
• Newton Dynamics 3.14 (optional)
• ImGui (optional)
• Nuklear (optional, deprecated)

The only mandatory dependency is SDL, the others belong to the corresponding extensions.

Runtime dependencies are automatically deployed on 64-bit Windows and Linux. On other platforms, you will have to install them manually.
