World Memory

World Memory it is a prototype of Backup Optimization mod, It add a way to revert back the chunks where you stand and elsewhere to a previous state without having to do backups or restarting a server simply "rewinding time" to a previous iteration of the chunks in a single click.

All chunks are saved in plained strings hashed inside the world file hence reducing the space needed for a normal back up file.

What is saved by the mod ?

• States before server crash
• States before corrupted chunks ( Not fully tested but working )
• States before and after explosion with an automatic rewind in case of crash
• NBT data of Mobs that has extra data ( Wolves, villager, horses, renamed entity etc... )
• NBT data stored in blocks ( bed, chest, signs, red stone etc )

Any and all modifications is recorded (normally i hope 🙏) and can be rewinded.

What is not saved and will in the future be saved ?

( yaya i know i misspelled future and i added the "E" )

• Player Inventories So far only mob/entities with inventory are saved and can be restored. As for player it is currently not yet implemented given it may cause duplication dupes ( since a player CAN respawn ) for now this feature is "here" but only work for (normally) Hardcore Worlds

• External mods in general Some future proofing was done already if a mod adds some tnt just with more power the mod can revert it back but what i like to call "special cases" are not rewindable yet ( custom explosions etc )

The mod is FOR NOW Vanilla+ Intended as a way for server owners to rewind griefed chunks and areas.

Bear in mind that this is a prototype and probably not as optimized as i wish it be. Any issue please report it on my discord or via DM's thank you so much.

Short Q&A:

Q1: Will there be a version for NeoForge

A: Yes. But i'm alone so it will take time given i have 0 knowledge on Neoforge yet. And no unfortunately no Forge version in mind but it is slightly considered.

Q2: Will there be a [Insert obscure minecraft version] of the mod ?

A: 1.20.1 and higher take it or leave it. Yall can fork it and backport it i simply ask for my name in little letters at the bottom.

Q3: Will there be some version that may be skipped ?

A: Beside what's said in the previous question i will maybe make a 1.19.2 version and also if i find a version too exhausting ( According to modding summary 1.21 is a pain ) i will skip it. Keep in mind i am alone at the moment i am no team leader and i prefer it that way for now.

Q4: Does this mod have an extra scope ?

A: Yes. This mod is simply an happy coïncidence of me thinking of ways to make time travel possible in minecraft and has such will in the futur be more than simply a "back up mod"
