Loot Chests and More! Custom Structures Ep 3 (Minecraft 1.20.4) 

Placement priority could be useful if you're doing a 3d space like a dungeon or a big building with rooms with height of multiple rooms/levels. These rooms might never or rarely generate since the top room will take the space above, but if you force to generate the bottom rooms first the problem is resolved.

This is a great series, thank you, hope to see more data pack tutorials!

Please don't stop uploading such nice Videos❤

15:55 -- One might use the direct alias to do things like interweaving vanilla jigsaws with custom ones. For example, add a variant of the taiga village to the new grove biome, where start_pool is the same as the vanilla taiga village center (minecraft namespace and all) but you could use a direct pool alias to swap the roads with heavily snowed ones that you designed and trade some of the decor for icy trees. Basically, useful for any one-to-one swap when you don't want to redo everything in the original.

those exclusion zones solve ALL my problems. 11:25 I can tell you why - the village is a form of a tree data structure and the timing of generating the leaves(ends) is determined at the highest node in the tree possible. this chains, meaning that if your houses weren't leaves and had several blocks spawning around them, then it might matter what the placement priority is on the road, after the placement priority of the village center is taken into account. 11:58 why depth first? because in breadth first, when several branches collide they will limit each other as they go. in depth first, you'll get some "trunks" that are more fully fleshed out and the last branches will hoard all the failures (in theory). pros and cons to each method. - average glamour across tree's branches, or a few far more glamourous branches.

LEARNING

I’m glad this popped up in my recommended after the previous two videos. (o°-°)b great stuff, you have a very clear voice and good explanations. Are the loot tables called as soon as any player opens the chest? (Or if the chest is destroyed). In other words: are the contents of loot chests (be it player generated like these, or vanilla like shipwrecks and villages) in a kind of superposition until accessed for the first time, and not simply filled on world/chunk generation?

This is a great tutorial series! I do have to ask, how does one make a structure that will spawn in multiple biomes?

Cool features! Could it be that the aliases are an extension of a given name like "Graveyard" and then more specifically "graveyard A" so that you can call "Graveyard" on a specific road or branch of roads and give it an alias for different biomes or call it only if a specific layout is possible? Forgive me, I have absolutely no knowledge of how the jigsaw blocks work other than what I have learned from your videos. I just had this idea as I was watching. Thanks for sharing your knowledge.

you mentioned the exclusion zones. is there a way to purposely overwrite general Minecraft Villages?
