Description

LoTAS-Light

Continuation of LoTAS for versions higher than 1.20.3, but with a reduced feature set

Needs Fabric-API

Why remove features?

Updating LoTAS to new versions was always very tedious due to the large feature set… Testing and verifying each feature was hard and with Mojangs faster release schedule, we could not keep up (especially if Mojang rewrites everything between minor versions)
Mojang patched a lot of things, so LoTAS's features would be reduced either way

Features

Improved /tick command

/tick rate supports tickrates lower than 1
A second /tick freeze by simply typing /tick rate 0, which also freezes the player
Tickrates higher than 20 also affect the player

Tickrate keybinds

Same deal as LoTAS

. increases the tickrate
, decreases the tickrate
F8 toggles /tick rate 0
F9 advances 1 tick while the game is frozen

Savestates

/savestate command for "quicksaving" and "quickloading" a minecraft world
J and K for saving and loading respectively

Item Duplication

Press Pause to save the game with the item in your inventory
Throw out the item out of your inventory or put it in a chest
Press O
Rejoin the world

Config

/lotaslight for changing the config

No Multiplayer support!!

The reason why this mod doesn't support multiplayer is simply: Savestates.
Basically Mojang never intended a quickloading feature, so to load a different world,
it is intended that you stop the Minecraft server (Imagine restarting and reconnecting to the server for every savestate).
Changing this requires a lot of work, more than I am willing to put into this mod. If you want to see (somewhat) working multiplayer savestates, check out TASmod
