Slothy's Tree

Slothy's Tree is a client-side Fabric mod for browsing, applying, and building custom Minecraft resource packs — without leaving the game.

Features

Pack Browser

Browse 40+ curated resource packs by ilyslothy. Apply any pack with one click. Filter by tags, sort by community stars, and see featured community picks.

Texture Builder

Mix and match item textures, GUI elements, particles, and sounds from different packs. Build a custom pack locally and save it to your library.

CIT Support

OptiFine CIT (Custom Item Textures) — item names, damage, NBT, and related rules.

Minecraft CIT on Modrinth downloads 1.21.8 Built into the main jar 1.20 – 1.21.1 Use CIT Resewn for your version (recommended). The legacy Slothy's Tree jar includes a fallback engine that automatically yields when CIT Resewn or similar is installed — no separate Slothy CIT companion jar. 1.21.9 – 1.21.11 Pack browser and Texture Builder work now; embedded CIT for these versions is still in development — do not expect full CIT parity yet.

Community

• Star packs in the browser (toggle on/off)
• Upload packs for moderator review (optional)
• My Uploads dashboard to track submission status
• What's New screen after updates

Extras

Kill effects, Feather profile import, local pack library, and customizable UI themes.

Screenshots

See the Gallery tab on this project page for labeled screenshots (Pack Browser, Texture Builder, in-game custom items, and more).

Copyright & catalog

• Slothy's Tree (mod code) is MIT — see the LICENSE in the repository.
• Default catalog packs are created and distributed by ilyslothy for use with this mod. Do not re-upload those packs elsewhere without permission.
• Community pack uploads are moderated before they can appear in the public catalog.
• Portions of the embedded CIT fallback are adapted from CIT Resewn (MIT).

Network connections & data collection

Per Modrinth Content Rules §1.11 — this mod makes optional and required network requests. The mod works offline for many features using bundled catalog data; online features need the connections below.

1. Pack catalog & downloads (GitHub Pages)

Host: https://ilyslothy.github.io/Slothy-s-Tree

When What is sent What is received Opening Pack Browser A random install UUID (X-SlothyHub-Voter header) when fetching star counts packs.json catalog, star counts Applying a pack Standard HTTP GET (no account login) Resource pack .zip files Texture Builder Standard HTTP GET textures.json index, PNG/OGG preview files

Data collected by the mod author on this host: none beyond normal web server logs (IP, user-agent) if you visit the site. The mod does not send your Minecraft username or Mojang UUID to GitHub Pages.

2. Community services (Cloudflare Worker)

Host: https://slothys-tree-bot.elytrapacks.workers.dev
(Override in mod settings → heartbeat URL if needed.)

When Endpoint What is sent Purpose While playing (~every 14 min) POST /v1/heartbeat Random client UUID only (stored in config/slothyhub.json) Aggregate “active users” stat for Discord /modstats Starring a pack POST /v1/pack-star Client UUID + pack ID Community star counts Loading pack list GET /v1/pack-stars Client UUID (header) Your starred packs + counts Only if you upload a pack POST /v1/pack-submit Pack zip, name, description, tags, optional contact, client UUID Moderator review queue Only if you use My Uploads GET /v1/submit-status Client UUID Your submission statuses

Not sent: Minecraft username, Mojang UUID, chat, world data, or installed-mod lists (except the pack file you explicitly upload).

Stored server-side: star votes (client UUID + pack ID), heartbeat presence (~15 min TTL), upload metadata until approved/denied. You can regenerate your local UUID in mod config (voterId).

3. Direct pack URLs

Some catalog entries link to GitHub Releases or other HTTPS URLs listed in packs.json. Downloading those packs is a normal GET request initiated when you click Apply.

Offline behavior

• A bundled pack catalog ships inside the jar if GitHub Pages is unreachable.
• Texture Builder falls back to bundled/local scans when the web catalog is empty.
• Heartbeats, stars, and uploads require the worker; they fail silently or show an error in UI if offline.
