CraftStats

A new editor and about 190 new stats: 294 in total, across mobs, blocks, items, players, and three new types (projectiles, enchantments and the world itself).

Downloads: pick the jar for your loader and Minecraft version: craftstats-fabric-1.2.0+1.21.1.jar, craftstats-fabric-1.2.0+1.21.11.jar, craftstats-neoforge-1.2.0+1.21.1.jar or craftstats-neoforge-1.2.0+1.21.11.jar. Requires Architectury API (13.x for 1.21.1, 19.x for 1.21.11), and Fabric API on Fabric.

Beta. Every build starts a real server and the game client on both loaders and both Minecraft versions. The tests apply every hook into the game, check a sample of the new stats on real mobs, blocks, items, arrows and enchantments, open every editor page, and in a singleplayer world apply stats through the network and throw a boomerang. Not every one of the 294 stats is covered by a test, and it hasn't had much hands-on play yet, so please report anything odd.

New editor Looks like a vanilla menu: the usual background, buttons and text boxes. Tabs for all seven types, a searchable list with item icons, and a "changed only" filter. Stats are grouped into category cards (Combat, Movement, Drops & Death...). Click a card to see its stats, or type in "Search stats" to find any stat. Every stat has a tooltip that explains it and shows the allowed range; an x button puts it back to default. The randomizer shows a preview of the rolled values before you use them.

Commands accept the new types: /craftstats reset world, /craftstats randomize projectile minecraft:arrow, /craftstats preset load overcharged enchantment minecraft:sharpness... Config toggles for the three new editors. The server clamps every value to its allowed range (no more accidental world-ending explosions). Changed Item stats removed in 1.1.2 because they did nothing (boomerang, throwable...) are back, and they work now.
