    Proof-of-concept time-travel debugger for the Bevy game engine, built using Rerun.

  • Their organizatio nand release process is top-notch, with some of the most high quality changelogs and migration guides I've ever seen in any project, and releases are rare enough (~about once a quarter) to just not be an issue.

    The community maintains compatibility matrices such as this one [2], and things generally just work :tm:.

  • What's the performance of this like? It seems really appealing. I would love to be able to use it to debug https://github.com/MeoMix/symbiants because I use RNG heavily to add variance to the world and that, combined with indeterminate execution order of systems, can really leave me scratching my head sometimes.

    However, I'm building using a tilemap that's 144x144. So I've got ~21000 entities to log. It seems impractical to snapshot the world every tick, but maybe if it were able to snapshot deltas or something?
