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? 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."
