Tilemaps, Multiplayer, and Mesh merging
2024-02-19
Welcome to another week in the Bevy ecosystem!
This week we've got a wide assortment of showcases, from 3d movement to world generation and more than a few mentions of multiplayer networking.
The long awaited bevy_ecs_tilemap support for Bevy 0.12 is released. This brings bevy_ecs_ldtk's support for Bevy 0.12 with it as well.
Alice posted another #bevymergetrain on mastodon. These threads are always a great place to gain some additional insight into currently open pull requests.
Jondolf added Mesh::merge which makes combining multiple meshes into one mesh significantly easier.
let mut cuboid = Mesh::from(shape::Box::default());
let mut cylinder = Mesh::from(shape::Cylinder::default());
let mut torus = Mesh::from(shape::Torus::default());
cuboid.merge(cylinder);
cuboid.merge(torus);
If you're looking to get started contributing, perhaps consider trying to document the Image type or ScheduleLabel's dependencies.
Bevy 0.13 is coming soon. Although Bevy's release schedule aims for a release every 3 months, there is no firm release date even though we can already start to see preparations for the release.

¿Quién es el Mechaburro?
devlog
¿Quién es el Mechaburro? was originally an entry to the very first Bevy game jam (The theme was "Unfair Advantage").
¿Quién es el Mechaburro? is a singleplayer/local multiplayer game (up to 8 players) with bots (8 total burros) inspired by twin-stick shooters, aspects of mario kart and a card game I played with my family growing up called "Burro."
This devlog covers a whole host of new features, upgrades across bevy versions, and showcasing at a local arcade bar.
