PolyHitbox
An extremely customizable hitbox mod
Quick answer
Which PolyHitbox release should I use?
PolyHitbox v1.1.3 targets 1.21.10 with Fabric. It must be installed on the client. Do not install it on the dedicated server. All 3 required mods have matching files.
Where it goes
Is PolyHitbox required on the client, server, or both?
It must be installed on the client. Do not install it on the dedicated server.
This file is marked client-only.
What else does PolyHitbox v1.1.3 need?
v1.1.3. Change the file and its required mods may change too.
Install Fabric Language Kotlin, OneConfig, Compose Multiplatform first. We found matching files for this game-version and loader setup. 1 comes through another mod in the chain.
1 extra mod was pulled in by another dependency. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.
