+++ title = "This Month in Rust GameDev #49 - August 2023" transparent = true date = 2023-09-16 draft = true +++

Welcome to the 49th issue of the Rust GameDev Workgroup's monthly newsletter. Rust is a systems language pursuing the trifecta: safety, concurrency, and speed. These goals are well-aligned with game development. We hope to build an inviting ecosystem for anyone wishing to use Rust in their development process! Want to get involved? Join the Rust GameDev working group!

You can follow the newsletter creation process by watching the coordination issues. Want something mentioned in the next newsletter? Send us a pull request. Feel free to send PRs about your own projects!

Tunnet (Steam, itch.io) is an upcoming short puzzle/exploration game about digging tunnels and building computer networks.

In August, a new version of the demo build has been released. Here are the most notable updates:

  • The game is now better optimized to run smoothly on the Steam Deck.
  • Some of the textures have been revamped and are now slightly more detailed.
  • The animations of the character portraits have been improved.
  • Several minor quality of life improvements like the ability to sprint have been made.
  • A basic egui-based crash reporter will now be displayed when the game process ends unexpectedly.

Oort

Asteroids-like vector graphics with ships and missiles made out of simple geometric forms A fleet of ships

Oort (GitHub, Discord) by @rlane is a programming game where you write Rust code to control space ships in combat against other players. Your code needs to manage the thrusters, guns, missiles, comms, and radar of each ship in your fleet. There's a series of tutorials where you can solve key problems one by one, such as leading moving targets or missile guidance. The game runs in your browser via WebAssembly.

Oort has started running weekly tournaments and the AIs have gotten more and more sophisticated each time. Check out this recent tournament writeup where the top players discuss their strategies.

Library Updates

Dexterous Developer

Dexterous Developer by @lee-orr is an experimental hot-reload system for the Bevy game engine. Features:

  • Define the reloadable areas of your game explicitly - which can include systems, components, and resources (with some limitations).
  • Reset resources to a default or pre-determined value upon reload.
  • Serialize/deserialize your reloadable resources & components, allowing you to evolve their schemas so long as they are compatible with the de-serializer.
  • Mark entities to get removed on hot reload.
  • Run systems after hot-reload.
  • Create functions to set-up & tear down upon either entering/exiting a state or on hot reload.
  • Only includes any hot reload capacity in your build when you explicitly enable it - such as by using the CLI launcher.
  • Cross-platform/cross-device hot reload - run a "hot reload server" on a dev environment, and execute the application elsewhere.

The library is quite new and currently known issues include: mobile/WASM support and the need to pre-define events&states.
