Danmokou is a danmaku (bullet hell) engine built in C# for Unity. It is free (as in free speech) software. The source code is on Github: https://github.com/Bagoum/danmokou
See the website for a friendly introduction to what DMK can do.
Setup and tutorial instructions can be found here.
The changelog can be found here.
Documentation can be found here.
There is a VSCode extension for DMK's scripting language, which can be found here.
The source code is licensed under MIT. See the Danmokou.LICENSE file for details, as well as information on non-code assets. Note that submodule projects may have different licenses.
Is there a tutorial?
Go to https://dmk.bagoum.com/docs/articles/setup.html for setup and tutorial instructions
Are there any examples?
For real game code, see the MiniProjects directory. There are many small game scripts there, such as the scripts for this Ikaruga-style jam game or the scripts for this Flappy Bird-inspired jam game. You can also check out the scripts from Spirits in Memetic Paradise if you have that installed as a submodule.
Under the Patterns folder, everything in examples and feature testing should work. The scripts there are fairly simple, but don't have many comments. The scripts in Patterns/bdsl2 are instructive for learning about the scripting language's features.
How difficult is it to port scripts from (DNH/LuaSTG/etc) to this engine?
You'd have to rewrite any scripts from scratch. The scripting language is highly opiniated. For example, bullets are fired through repeater objects instead of for loops.
Can I submit PRs?
You may freely submit PRs for bugfixes or new features. If you submit a PR, you must license that code under MIT or a MIT-compatible license. If you would like to submit non-code resources, please contact me.
How do I contact you?
Email reneedebatz@gmail.com (keys on https://keys.openpgp.org/) or contact me on Discord (Bagoum#4773).
Why Unity?
Honestly, I'd rather not be using Unity, but I don't know of any engines which support all this project's requirements, and at this point there's too much investment in Unity-specific handling to have a simple port.
What does Danmokou mean?
See Chapter 18 of IoMIoE.
What does 陰陽葬 mean?
This is the Japanese title for my Touhou fangame Spirits in Memetic Paradise. You can play it here.
This repository has some test coverage.
In Unity, there are "edit-mode tests", which can be run statically, and "play-mode tests", which are run while the game is running.
Definitions for these tests are under Assets/Plugins/Danmokou/Testing/Tests and Assets/Plugins/Self/Testing/PlayTests respectively.
Most play-mode tests operate by running some state machine and checking the output game state. State machines used for testing are in the folder Assets/Pattern/Tests.
Scenes used for play-mode tests are in the folder Assets/Scenes/Testing.
A significant amount of the engine's logic is in the Suzunoya repository, which is a pure C# project with a good amount of NUnit-based coverage.
