0.1.1 (boss stutter fix)
A bug-fix release.
Fixed: the small, regular freezes (one every second or two) while fighting ULTRAKILL bosses such as V2 and Gabriel. The game
was rebuilding its enemies' walking map after every explosion and reading far more terrain than needed. Now it only does this for
enemies that walk, and only around you and them. Those hitches dropped from up to 100 ms to about 5 ms.
Download both files:
ukpassthrough-0.1.1.jar: the Minecraft half. It goes in Minecraft'smodsfolder.UKPassthrough.dll: the ULTRAKILL half. It goes inBepInEx\plugins.
Updating from 0.1.0: delete the old ukpassthrough-0.1.0.jar from the mods folder before adding the new one (with both there,
Minecraft won't start), and replace UKPassthrough.dll.
You need: Windows, Minecraft: Java Edition 26.3 with Fabric Loader 0.19.3+ and Fabric API, and ULTRAKILL (Steam) with BepInEx 5,
on a save that has finished the tutorial and has the Revolver (the first pistol). It's single-player only.
The step-by-step install, the keys and the known issues are in the README.
This is an early release, so expect bugs. Please report them as an issue with both games' logs.
No game files or decompiled code are included. It was written with Claude Code.
