Have you ever wanted to see a map of how a specific #minecraft seed generates? But you are playing with datapacks that modify worldgen? I've got an online solution for you: map.jacobsjo.eu (Works with some mods too, but not with all) #mcdev #DatapackShowcase

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers. The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

Today is the 5th anniversary of #Minecraft data pack #worldgen! Snapshot 20w28a added the ability to define custom biomes, structures, etc. through data packs. It's hard to overstate the impact this change had on modded worldgen. Very proud of what our community has made with it so far! #mcdev

I've tried to fix that one multiple times over the years. Finally had the right idea of how to do it. It was surprisingly simple.

The wonderful @jacobsjo.eu has just fixed a longstanding texture bleeding issue in NBT Viewer (and other tools using deepslate) 🎉 Compare these before/after images for yourself:

I almost fell for a scam site today, pretending to be the homepage of an OSS project that I was looking for. It looked convincing until I scrolled to read more text. LLM slop is getting scary good at "looks good at a glance". I don't even know _how_ they managed this. Feeding LLM into LLM somehow?

I'm disgusted by the concept of generative AI tooling for Minecraft mods. This isn't the first one and it sure as hell won't be the last, but it made my blood boil regardless. (1/5) #mcdev #minecraft

Turns out the firefly particles make very good nether ambient particles too. In the Lavaflow 1.21.5 update, I've added them to the ghost forest. #mcdev #minecraft

Trying to figure out ancient debris distribution in Lavaflow, I wished to have a visual marker for each placement position. So today I've implemented a debug renderer for feature locations into my Worldgen Devtools mod. Just released that in version 1.3.0 for mc 1.21.3 and .4. Open with F3+F #mcdev

Finally published a first Alpha of "Lavaflow", a #Minecraft worldgen #datapack / mod that completely overhauls the Nether. It includes lava rivers on 2 heights with lavafalls between them, proper valleys, oceans and more. Check it out on modrinth: modrinth.com/datapack/lav... #mcdev

A change I would like to highlight from #Minecraft 1.21.4 is a bug-fix: MC-272062 - "Dimension padding doesn't affect the start piece." This fix makes it possible for data packs to add structures to the end without them ending up in in the void at y=0. #mcdev

For custom sky islands dimensions the only way around this issue until now was to change the biome layout to have a different biome at y=0. This is not possible to do with the vanilla end though.

I've also updated my datapack map to reflect this change if 1.21.4 is selected. In the process I also added the y position of the structure start to the markers.

I'm really glad I'm just developing a website for making zip files for a block game. Takes away a lot of pressure when rolling out major rewrites!

- This also means that the recently used menu now works in Firefox - Folder datapacks continue to be referenced from disk. Since folders are mostly used during development this means that updating the datapack is automatically reflected in the map: In dev mode just press the reload button.

- Since referencing from disk doesn't work in Firefox, selected folders aren't added to the "recently used" list there. The reload button also doesn't really work. Thus for datapack development, I recommend using a different browser. (To be clear, those last 2 point have not changed in this update)

A few more details: - The datapacks downloaded from modrinth are cached locally, so each version is only downloaded once. - If you select a zip file the "recently used" menu now copies the zip file into browser storage instead of referencing it from disk.

You are up to date.
