CLASSIC MECHANICS
By Wilozyx
v1.26.2 for 1.21.5


Classic mechanics is a datapack I've made into my passion project recently! The goal of this datapack is to re-insert older features, tweaks and mechanics of the game into modern minecraft, this includes various things from beta, alpha, infdev, indev, classic, early release, etc.

The datapack comes with 'modules' - each one is a different tweak/feature/mechanic, all of them are toggle-able/configurable at any time and are only ever active if enabled, to preserve game performance.
The datapack currently has over 264 different modules!

Remember that all modules are disabled by default! To enable them you must type in the command for the options/config message (listed below)


Config/Options message command:
/function classic_mechanics:options_message


NOTES
1. This datapack aims to be compatible with several other types of datapacks, meaning, it purposefully does not touch things like world/terrain generation and actively tries other, different methods for results that would require such a thing!

2. This datapack and all other work I've put out is fully public property. You can freely edit/modify/tweak/remake/copy/add to your modpack/add to your own pack/etc, anything you wish!

Reminder!

The current download of the datapack in this Planet Minecraft is for the most recent version of minecraft! (1.21.5)
If you want this datapack for previous versions of the game, check out the modrinth page, in the 'versions' tab!

Please bring back the beta bow, its the most precious thing from the beta in my humblest opinion

Hey, I've just tested it. 1.21.5, latest version and all and it seems to work fine on my end. You're using version 1.23.0 of classic mechanics right? Are you sure there are no mods interfering with it possibly? If you want some further help you can shoot me a message on discord (@: wilozyxx) and we could talk more there
