Custom Map Resetter

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader

Minecraft version

⬇ Download for 1.20.5–1.21.4 · Fabric⬇ Download for 1.20.3–1.20.4 · Fabric⬇ Download for 1.19.3–1.20.2 · Fabric⬇ Download for 1.19.1–1.19.2 · Fabric⬇ Download for 1.17.1–1.18.2 · Fabric⬇ Download for 1.20.5–1.21.4 · Quilt⬇ Download for 1.20.3–1.20.4 · Quilt⬇ Download for 1.19.3–1.20.2 · Quilt⬇ Download for 1.19.1–1.19.2 · Quilt⬇ Download for 1.17.1–1.18.2 · Quilt
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

A mod that copies and reloads a specific world file for reset efficiency in custom map speedrunning.

The version-by-version changelogs are in the original github releases, or the commit history if you're that kind of person.

how to use (written by Qwuiblington)

shift + click the diamond boots icon on the main menu next to singleplayer to select a world click on the diamond boots again to start resetting that world once you're resetting, the save & quit to title button will immediately create a new copy of the world & put you in it to exit, you have to go into options, & click the "stop resets & quit" button on the bottom left corner of the screen (you may also turn off autoresetting, to only make use of the world copying & deleting functionality)

after this, you can shift + click on the diamond boots again & click "delete session worlds" to delete every copy made by the mod if you close the game, it won't save which worlds were created by the mod, so you'll have to delete the saves manually or with an external script

attempt counters are kept track of by world folder name, & stored in [instance folder]\config\custom-map-attempts.txt there is also a read-only file containing only the current map's reset count, for obs file reading, in [instance folder]\attempt.txt
