Danmakufu - Create your own bullet hell patterns

[SupahVee]

Danmakufu is a Japanese application that uses its own scripting language (similar to C#) to let users create bullet hell patterns, or entire bullet hell games. The scripting engine is pretty powerful, you can also create custom players, custom bullets, etc.

Danmakufu is a sort of MUGEN for bullet hell games. Here's something other users created with it.

Maybe that wasn't the best video to introduce you to Danmakufu.

Here's something more serious.

And an example of a completed Danmakufu pattern script:

#Player[FREE]

I love Danmakufu because it's a nice break from traditional programming; you have an idea for an interesting bullet pattern, you script it, and you play it. No need to mess around with rendering and complex stuff.

It's fun.

[QUOTE=Samuelgames;20832402]They've even released full games for this thig, Touhou: Concealed of conclusion is a nice example.[/QUOTE]

Indeed. CoC is pretty good, it's practically 4 games in one.

Also, I forgot to post [url]http://bulletforge.org/[/url] - which is a beta site where everyone can upload and share their scripts.

Looks pretty cool, but I don't see how it's similar to C#. It has curly braces, and that's about it

[QUOTE=turb_;20839853]Looks pretty cool, but I don't see how it's similar to C#. It has curly braces, and that's about it[/QUOTE]

It has no pointers, also it has references for OBJ Bullets.

[turb_]

Lots of languages have references but not pointers. By your logic I could say this was similar to Perl

[SupahVee]

Well, I mainly program in C# and I had no trouble using Danmakufu scripts.

You're right though.

This is kinda hard. I wish theres a english patch. And you need Applocale or japenese locale to run this shit.

I agree about Applocale, but what do you need the english patch for?
