Sinytra Connector #1343 (swimming fix)
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
⬇ Download on CurseForgeThe author built this one for Minecraft 1.21–1.21.1 on NeoForge. On other versions it may install and then do nothing.
No longer necessary as of Sinytra Connector v2.0.0-beta.10!
This mod implements a workaround for https://github.com/Sinytra/Connector/issues/1343, which prevents swimming (and causes a few other issues) when Sinytra Connector and certain Fabric mods are installed alongside one another. It will be taken down once the issue is properly fixed upstream.
More specifically, this mod fixes NeoForge's built-in attributes after Sinytra Connector accidentally nullifies them - including SWIM_SPEED.
