About this project
What does Entropy: Chaos Mod add?
Entropy: Chaos Mod
Entropy is a Minecraft Chaos Mod where random events happen every 30 seconds. The events are selected randomly from a pool of 120 (and growing) events that can be anything from meteor rain, physics changes and much more.
Event and timer duration can be configured from the Settings menu!
Entropy was heavily inspired on the excellent work of pongo1231's Chaos Mod V for Grand Theft Auto V!

Multiplayer
Play Entropy with friends! Each random event happens around each player. Each connected client can configure Twitch Integrations independently and will send poll results to the server.
Chat Integrations:
Twitch Integration:
Entropy includes integration with Twitch! Viewers of a streamer can vote the next event using the stream chat!
To enable Twitch Integration you'll need a Twitch OAuth Access token, you can generate using this tool (or any other OAuth token generator tool). Write your OAuth Access Token and your channel name in Entropy Settings.
YouTube Integration:
In a similar fashion to the twitch integration, Entropy also includes the ability for YouTube streamers to connect with their YouTube Live Chat for event voting.
It requires the creation of a Google Cloud Platform project and some configuration. Click here for a video tutorial, there's also a written guide in that video's description.
NOTICE: YouTube implements a daily limit of requests limiting the amount of time the mod can be played with YouTube integration. In order to increase the playable time, YouTube integration votes will be counted less often, making the vote bars look laggy. Usually the quota is reached after around 3 hours. You can change the delay between each check in the YouTube integration settings.
Discord Integration:
Users of a discord server can vote the next event by using the Entropy Discord integration. TUTORIAL: https://www.youtube.com/watch?v=waj82ownAKw
