Practical write-ups on commands, datapacks, building and server performance — each one paired with the tool that does the work.

Bossbars and titles: persistent state, timings, and the value/max split

A bossbar survives restarts and a title does not. Here is the create-then-modify pattern, the fade timings people set backwards, and how to drive a progress bar.

Custom paintings and music discs without replacing the originals

Both became datapack registries, so you can add new ones instead of overwriting vanilla. Here are the two files each needs and the sizing rule paintings must follow.

Dialog screens: building real menus without a mod

Datapack dialogs give you a proper window with inputs and buttons. Here is the JSON shape, how a button runs a command, and how it compares to the book-menu hack.

A pot takes four sherds, one per face, and the order you place them decides which face gets which. Where every sherd comes from and how to skip the digging.

Camera cutscenes without a mod: keyframes, interpolation and spectator tricks

Two ways to move a camera in vanilla — a ticking teleport function, or the timeline registry. What each is good for, and the smoothing that stops it looking robotic.

server-icon.png: the exact requirements, and the management API nobody uses

64x64, PNG, at the server root — get any of the three wrong and the icon silently does not appear. Plus the JSON-RPC management API that replaced screen-scraping the console.
