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
