Practical write-ups on commands, datapacks, building and server performance — each one paired with the tool that does the work.
The /give command after data components: what replaced NBT tags
1.20.5 replaced item NBT with data components, and most /give snippets online are still written the old way. Here is the mapping from the tags you know to the components that work now.
Nether portals that link where you want them to — the 1:8 rule in practice
Portals do not pair by coordinates alone. Here is the search box the game actually checks, why your portal keeps connecting to the wrong one, and how to force a clean pair.
Torch spacing for spawn-proofing: the exact number, not a guess
Hostile mobs need block light 0. Torches emit light 14 and lose 1 per block. That gives a precise grid — and a different answer for floors, ceilings and open builds.
Best Y level for every ore after the world height change
Diamonds are not at Y=11 any more. Each ore now has a triangular distribution with its own peak, and a few have a second band. Here are the real numbers from worldgen.
Ominous Bottles and Bad Omen I–V: what each level actually changes
Bad Omen no longer starts raids on its own. Here is what the five Ominous Bottle levels do to trial chambers and raids, and the give command for each.
The gamerules worth changing — and the defaults people get wrong
There are over 40 gamerules and most guides list them without saying which matter. Here are the ones that change how a world plays, with their real default values.
Whitelist, ban and op: the server commands that behave differently than you expect
Whitelisting does not kick players already online, /ban needs a reason to be useful, and op level matters more than the op list. The details that bite server owners.
Trial chambers: making spawners ominous and what the vaults actually drop
Ominous vaults hold the Heavy Core, the Mace's key ingredient, but only if you make the chamber ominous first. Here is the sequence, the key economy, and what solo versus co-op changes.
/execute: why as/at order matters and how store actually works
Most broken execute chains come from confusing who runs the command with where it runs. Here is what each subcommand changes, and the order that fixes it.
/fill and /clone: the 32,768 block limit and the modes that get around it
Both commands cap at 32,768 blocks per call by default and refuse anything larger. Here are the hollow, outline and replace modes, the clone masks, and how to move a build bigger than the cap.
