    About
    Every 60 seconds you will get a complete random chaotic effect

    - Such as: Spawn a mob, get an item, or something crazier, like an anvil apocalypse or start a raid!
    - There are currently a total of 175 effects!
    - Click this to view the list with all effects!
    - Most effects last 3 minutes, but in some cases they last for 1 minute, 30 seconds or less
    - There's also two modes with less cooldown on effects, so you get one every 30 or 15 seconds, but all the effects will last for less time time
    Spectator Voting Mode
    The datapack also includes a mode for voting!

    - On spectator voting mode, spectator (the gamemode) players can vote for the effects the runner will be getting
    - Every 30 seconds, spectators will get a poll with 3 effects to vote for, then another 30 seconds after, the effect will be applied (one effect per minute)
    - If there is a tie, a random effect from the poll will be selected
    - Also includes a mode with more cooldown on effects, so you get one every 1:30 minutes, but they last 50% more of their usual time

    For now, it only works with players inside the world on spectator mode, since I don't have modding knowledge to do something like a Twitch chat voting thingy (pls help me if you know how)
    How to use
    How to use in version V1.4 (Minecraft 1.21.6):
    Simply press 'G' as the default keybind for quick actions or pause the game and select Minecraft Chaos to open the main menu. From there, everything should be easy to understand thanks to the new dialog system Mojang implemented.



    How to use in versions prior to V1.4 (Minecraft 1.21.4 or below):
    When you first join the world, you will get a message on your chat with some info. Click the text that it indicates to start, or type /trigger chaos.settings
    You will get this on your chat, click the squares on the left to select a mode

    You can also join a team at any point by using /trigger chaos.runner or /trigger chaos.spectatorIf you select a mode with spectator voting, you will also get an option to join either the Runner or Spectator team

    Credits

    Thanks to chaathon for drawing the thumbnail, you did an amazing job!
    Thanks to HaDeAnTheonlyone for the tags library, really helpful for certain things that I needed for the datapack!
    Thanks to Lordmau5, pongo1231, Bart de Bever, and Parik27 for making the original GTA Chaos Mod, which inspired me a lot to make this for Minecraft!

    Want to report a bug, suggest an effect or a change?

    Go to my github issues and create a new one. In the beginning of the title put something like (Effect) or (Bug) to label it, and then type the thing you want

    Enjoy the chaos!

    I'm not that good at making datapacks, and this is the first time I post a big one online, but I just wanted to make this since I had so much fun watching and playing runs with the GTA Chaos Mod! Thanks to Lordmau5, pongo1231, Bart de Bever, and Parik27 for making it!

    Twitch chat voting mode?

    As I said above, I don't have any modding knowledge, so I can't figure out a way to make this happen. I thought I could get someone who knows to help me do it, but I don't know anyone. So, if you like this datapack and have/know someone who knows how to make mods for the game and implement this, send me a DM on discord! Shaaaaaaaaaron :)

    I was trying to play with this datapack, but Minecraft told me that it was made for a newer version of the game. I updated to the latest version, but Minecraft still said it was for a newer version. I then noticed that this datapack is actually for version 1.21.11; I switched to that specific version, yet Minecraft *still* claimed that the datapack was for a newer version.

    A very good, but a little strange datapack, because it only starts when you re-enter the world. Other datapacks launch with /reload, but this one doesn’t.

    On the latest version, you can either press the Quick Actions key (which is G by default) or pause the game and select Minecraft Chaos. From there it will be easier by using the menus

    Thanks for making me aware of this. Just watched his video, and it was pretty entertaining. Not happy about not crediting, though. I left a comment even though it's unlikely it'll be seen
