About this Mod

HTSL Reborn

GitHub last commit By Redstone Studios

Overview

HTSL Reborn is a fabric mod that makes programming in Hypixel's Housing gamemode easier. With the help of SystemsAPI, we ported HTSL's syntax to latest versions. Now that we're based on a more modern loader, there's a large possibility for extra QoL features to come in the future!

Features

  • Language parity with HTSL (your HTSL scripts will work flawlessly!)
    • Expressions (Javascript math, etc.)
    • Compiler shortcuts (define statements)
    • Loops
  • Importing to Housing (with multiple methods:)
    • Add: adds new actions after existing ones
    • Replace: automatically replaces old actions with new
    • (PLANNED) Update: optimally adjust existing actions so import takes less time (soon!)
  • Exporting to code
  • File browser hot-reloading
  • Item support

Questions

How do I migrate?

To migrate from HTSL to HTSL Reborn, just copy all your imports into the new HTSL folder, located in the root of your minecraft instance. You should be good to go once things have been moved over.

What's better about this compared to the ChatTriggers module?

There are a couple of reasons why we abandoned HTSL to make this new mod.

  • We wanted to update to the latest version of Minecraft.
  • We wanted to leave the ChatTriggers ecosystem, opting for the power an actual modding framework gives us.
  • We wanted to start fresh with a clean codebase (the old one was starting to get out of hand).

What does that mean for you?

  • Fewer bugs (in the long term)
  • Latest-version (and multi-version) support
  • More features!
I need help!

Frequently Asked Questions

HTSL Reborn server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.

Is HTSL Reborn compatible with fabric?

HTSL Reborn officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with HTSL Reborn – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if HTSL Reborn consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
