# stream-chat-mod
# Stream Chat
A client-side Fabric mod that displays Twitch, YouTube, and TikTok live-stream
events in Minecraft. Twitch and YouTube events are received from Streamer.bot;
TikTok events are received from TikFinity.
## Current status
The project is at its initial implementation stage. The default and currently
verified build target is Minecraft 26.1.2 with Fabric. A separate legacy
client source set is retained for Minecraft 1.20.1.
## Initial setup
1. Install Fabric Loader 0.20.1 and Fabric API 0.155.3 for Minecraft 26.1.2.
2. Install Mod Menu to open the mod's settings screen from the Mods menu.
3. Configure the Streamer.bot and TikFinity WebSocket addresses in
`config/stream-chat.json` or in the in-game settings.
4. Start Streamer.bot/TikFinity and launch Minecraft. Enabled integrations
connect automatically; use the configured keybind or settings screen to
toggle them.
The Streamer.bot password, when configured, is stored as plain text in the
local Minecraft config file. Do not share that file or diagnostic logs without
checking them for private information.
The mod is client-only. It does not send stream events or chat messages to the
Minecraft server.
## Development
Use Java 25 for the Minecraft 26.1.2 target. Build with Gradle:
```text
gradlew build
```
The Minecraft version, Fabric Loader, Fabric API, Mod Menu, Loom, and Java
versions are declared in `gradle.properties`. Select matching versions there
before building a different Minecraft target. The legacy 1.20.1 source set
was verified separately; other releases need their own compatibility checks.

#
# Gradle start up script for POSIX generated by Gradle.
#
# Important for running:
#
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
# noncompliant, but you have some other compliant shell such as ksh or
# bash, then to run this script, type that shell name before the whole
# command line, like:
#
# ksh Gradle
#
# Busybox and similar reduced shells will NOT work, because this script
# requires all of these POSIX shell features:
# * functions;
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
# * compound commands having a testable exit status, especially «case»;
# * various built-in commands including «command», «set», and «ulimit».
#
# Important for patching:
#
# (2) This script targets any POSIX shell, so it avoids extensions provided
# by Bash, Ksh, etc; in particular arrays are avoided.
#
# The "traditional" practice of packing multiple parameters into a
# space-separated string is a well documented source of bugs and security
# problems, so this is (mostly) avoided, by progressively accumulating
# options in "$@", and eventually passing that to Java.
#
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
# see the in-line comments for details.
#
# There are tweaks for specific operating systems such as AIX, CygWin,
# Darwin, MinGW, and NonStop.
#
# (3) This script is generated from the Groovy template
# https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
# within the Gradle project.
#
# You can find Gradle at https://github.com/gradle/gradle/.
