SpacetimeDB is an interesting new type of relational database that I haven't quite wrapped my head around yet.

It is designed for real time massive multiplayer games and uses some sort event sourcing (CRDTs?) but has many more potential use cases than just games.

It works particularly well with .NET and C#. So I have cleaned up and simplified the C# quickstart sample.

Day 6 of learning Rust as a C# dev:
No classes. No objects. Just tuples, arrays, and a compiler that keeps you honest.

Rust’s types feel simple until they don’t.

Here’s what I learned:

Chris Woody Woodruff · Rust Scalar and Compound Types: Where Are My C# Classes? - Chris Woody WoodruffWhen I first started exploring Rust, one of my instincts was to reach for a class. You know the drill. Need to model some data? Write a class, slap a few properties on it, and maybe add a constructor or two. But Rust had other plans. On Day 6, I dug into Rust’s scalar and compound types and quickly realized that Rust doesn’t want you to start with classes. Instead, it hands you a small set of powerful primitives and says, “Let’s build something lean.”

#GameDev #FreeCode #Godot #CSharp If anyone wants to play with this, the code is here:

github.com/IanBadcoe/SubD_Test

(to be precise, that is the test project which has the real repo as a sub-module)

Semi-polished and moderately tested, there are some awkward corners...

The features are:
- build-control-mesh from cubes (lame)
- build-control-mesh from "cylinders" (prisms)
-- radius, roll, pitch, yaw for each section
-- set edges/verts sharp, or tag them for later retrieval
-- add holes, set their edges sharp or tag them
- normals for all polys/edges/faces

Omissions:
- no UVs yet
- there is a ton of Linq used, it works for me in editor, but may give GC stalls if used a lot in game...

Further work:
- I want to add a feature beyond "holes" where I can turn a hole into a "socket" into which another surface could be plugged, producing side-branches...
- if performance is a problem, rewrite in C++...

Talk to me if you need anything. I do bite, but I am (on average) a long, long way away from you 😄

Subdivision surface with hole edge diagonals and hole corners set sharp, resulting in a hole rectangular in profile, but with edges curving smoothly in and out through the cross-section

Day 5 of learning Rust as a C# dev:

Functions look familiar... until they don’t.

No return keyword, types after names, and the last line does the returning?

It’s weird. It’s clean. I kind of love it.

Chris Woody Woodruff · Functions in Rust: Familiar Yet Different - Chris Woody WoodruffToday’s Rust lesson hit a familiar note but with a twist. Writing functions in Rust feels almost like writing them in C#. Until, of course, the compiler reminds you that this language doesn’t always play by the same rules. On Day 5 of my Rust-for-C# developers journey, let’s break down function definitions, type inference, return values, and where Rust and C# shake hands... and where they give each other a suspicious side-eye.
