[bug#59391] [PATCH 0/1] gnu: Add Virality Engine

[Sharlatan Hellseher]

Hi Guix team!

This is a final patch which summarised my efforts to bring Virality Game
Engine to Guix.

There is one thing to note, some of the packages which are in Guix right now
were merged into Virality code base recently and upstream development
completely closed by the author (see README note):

Here is a list of them:
>   2290:               (url "https://git.mfiano.net/mfiano/seedable-rng")
>  10188:               (url "https://git.mfiano.net/mfiano/origin")
>  12838:               (url "https://git.mfiano.net/mfiano/pngload.git")
>  16850:               (url "https://git.mfiano.net/mfiano/shadow")
>  16889:               (url "https://git.mfiano.net/mfiano/umbra")

Other proposal I would think of is to move cl-trial and cl-vriality from
lisp-xyz.scm to game-development.scm as it's more logically bound to that
module.

> ./pre-inst-env guix build sbcl-virality cl-virality --rounds=2
> /gnu/store/cgljdd5vm8anxf9v0ips2vbalv6fp23k-cl-virality-0.3.0
> /gnu/store/8y3qv6f8w71l4zf1d4953xjq82a1mw01-sbcl-virality-0.3.0

+     "Virality Engine provides a system and workflow that helps describe the
+elements needed to write 2D or 3D games.  It was designed with several domain
+specific languages that make it easier to describe, manipulate, and use assets
+commonly found in game making.  Such assets include (but are not limited to)
+textures, materials, shader programs, and scene trees of actors that are
+available for instantiation.  Virality Engine also knows how to accept input
+from keyboards and most joysticks and gamepads.
+
+The component system is a hybrid model between an ECS and an object model.  The
+components are defined similar to CLOS defclass, and regular generic methods
+can be used with them.  Components are added to Actors which represent game
+concepts like players, scenery, effects, etc.  We define a component protocol
+invoked by Virality Engine to move your components to the next state and
+render them each frame.")
