Polder building, Jarl Playtests, and Hanabi Particles
2024-11-18
This week in Bevy we see Jarl start playtesting, further progress on Polder's building mechanics, and more.
We also see the release of some interesting new particle features in Hanabi, including mesh particles and improve trails.
The CLI working group has also produced the first release of a Bevy linter, which is possibly a great addition for sharing patterns and optimizations for the community.
bevy_lint
You might be familiar with cargo clippy which is a collection of lints to catch common mistakes and improve your Rust code. Clippy can be great, but projects like Bevy have specific usage patterns that would benefit from different rules.
On that subject, the CLI working group has released bevy_lint, a collection of lints to check for Bevy-specific footguns and optimizations, as well as enforce project-wide restrictions and standards. This is a work-in-progress linter that has rough edges, but the goal is to upstream it into the Bevy organization at some point.
Check out the release notes for instructions and how to use it and check out the talk this Thursday at the 7th unofficial Bevy meetup
This week the Merge Train is headed by François! The Merge Train is a maintainer-level view into active PRs, both those that are merging and those that need work.
