x_x — third-party & compatibility notices
========================================

Original Java code and project assets (except as noted below) are authored for
this mod. See LICENSE and fabric.mod.json for the project license.

This is NOT a redistribution of OptiFine, ItemPhysic, Better Dropped Items,
Interactic, Meteor, Wurst, CIT Resewn, or similar mods. No foreign mod packages
are vendored in this repository.


1) OptiFine / MCPatcher pack formats (CIT & custom sky)
-------------------------------------------------------
Runtime parsers under crittcat.x_x.util.OptifineCITRuntime,
OptifineSkyRuntime, CustomSkyResources, and related mixins reimplement support
for publicly documented OptiFine/MCPatcher property formats so user resource
packs can work in Fabric. That is format compatibility, not OptiFine source.

Optional courtesy: CIT Resewn (MIT) documents similar Fabric CIT concepts;
this project does not include CIT Resewn source.


2) Dropped-item Physics / 2D
----------------------------
DropSettings “Physics” and “2D” follow common client-mod ideas (items tumble
while falling and rest flat; or billboard flat drops). The implementation is
original to this codebase (vanilla ItemEntityRenderer structure + local
transforms). Feature similarity alone is not a copyright copy of ItemPhysic /
Better Dropped Items / Interactic.


3) Hit sounds — ACTION REQUIRED for bundled samples
---------------------------------------------------
HitSounds installs hurt samples under unique x_x:hitsound IDs. Layout and
event mapping intentionally mirror packs such as “hit_sounding_pack”
(damage/hit1–3 on hurt events).

Bundled OGG files under:
  src/main/resources/assets/x_x/sounds/hitsound/

are NOT covered by a blanket assumption that they are CC0 with the code.
If those samples were taken from another pack or creator, you must either:

  - replace them with original / clearly licensed audio, or
  - obtain permission and document the license next to the files, or
  - remove the bundled samples and ship empty pack slots.

Shipping someone else’s audio under CC0 without rights is a real copyright risk.
Code comments alone do not clear audio copyright.


4) User-supplied content
------------------------
Capes, skins, custom sky folders, ItemSwitch textures, and optifine_compat
content under config/ are supplied by the user at runtime and keep whatever
license the user had for those files. This mod does not relicense them.


5) Minecraft / Fabric
---------------------
Minecraft is property of Mojang/Microsoft. Fabric Loader and Fabric API are
licensed by their respective authors (not under this mod’s CC0 claim).
