Meshlets, Stable Interpolation, and Generalized ECS Reactivity with Observers! - This Week in Bevy

thisweekinbevy.com/issue/2024...
Release Candidate 0.14.0-rc.3 is out this week with one last new feature for 0.14 (Observers), an upgrade to wgpu 0.20 (previously 0.19), as well as assorted fixes for rc.2.
With the 0.14 release getting closer fewer major features are getting merged but we still have some great functionality to talk about.
As always you can keep up to date with the release using the 0.14 milestone.

[@chrisbiscardi]

Glad you're finding the videos useful!

[@Mint25pop]

I am always coming back for these videos! I hope you can keep this series going strong!

[@GeekMasher]

Always great videos on Bevy and ecosystem updates

[@luxluth]

the new observer looks amazing. It giving me so much ideas

[@chrisbiscardi]

Observers seem like a big deal. Very excited to see how they get used over the next few months.

[@indiedevcasts]

Thanks for the update!

[@morgomi]

Oh, that's great! I've been developing a 3D puzzle game with for a few weeks to explore Bevy more detailed way. Custom Primitives will be especially useful for my game! Thank you.

[@vicc8881]

As always I only understand the showcases, but I love the entire video, people are amazing. Thank you for this video 😉

[@chrisbiscardi]

Is there anything I can do in the overview that would help you to understand what's going on?

[@admazzola3569]

yay another shoutout for bevy_mesh_terrain_editor ha :D Yes the editor supports Terrain and it also supports Doodads-only so that grayboxed level is being built with only doodads, no terrain. My dungeons dont have terrain, only doodads. For the floor and walls and such. I think the similar way as morrowind did things

[@anafabula]

8:15 There is a game like that called Scanner Sombre. Not in bevy unfortunately. It didn't do very well, but cool concept.

[@peterhayman]

yaay its twibtime!! ❤❤❤

Hi Chris do you have link for this LIDAR ?

[@chrisbiscardi]

all links are on the website which is linked in the description. The video for the LIDAR is czcams.com/video/-UxX-84wa4I/video.html

How consistently does Bevy export to WebGPU?

[@chrisbiscardi]

It will export to WebGPU whenever you build it with the feature enabled. You can see the examples running in WebGPU on this page: bevyengine.org/examples-webgpu/

[@CreedWylder]

I haven't been able to access any of the discord links in the blog posts, it just takes me to a placeholder server. Would be nice to have non-discord links.
[Edit] you first have to join the Bevy server in order to see the links. Directly navigating to the links doesn't work, and looks like a broken server. Potentially needs an explanation on the blog post.

lmao showing the PR for correct lerping and then immediately showing an incorrect use of lerp smoothing bevy example as the next item is hilarious
