The client moves the pointer itself. A vanilla client reports where it is looking twenty times a second, and a pointer sent frame by frame could only be as smooth as packets happened to arrive. Now each reading of the aim becomes a one-tick segment of a schedule — from where the last one ended to the new reading, starting at a whole tick of the world's clock a little ahead — and the text shader plays it by the client's own clock (GameTime), showing each segment only in its tick and a hold at the end. When a packet lands no longer matters, so the pointer goes through the readings end to end with no jump, the way the client moves an entity between two updates, about a tick behind the hand. Clients on the 26.2 pack only (input.client-motion); older ones are sent every frame as before. Found and measured on a live client with the new /vui debug mtrace (every reading and every packet for ten seconds) and /vui debug clock.

Each player sets their own pointer — /vui cursor, or VoidRpUi.cursorSettings(player, then) from a server's own settings page: speed, smooth or frame by frame, and the clock alignment, lined up against a ruler. Kept in cursor.yml; anything left alone follows the input section.

Experimental: the page in the world. For whoever holds voidrp.ui.world (operators by default), the page can be drawn on a text display in front of the player, in a dark room, with the crosshair as the pointer — no delay at all, since the client turns the camera itself. The text shader's world variant lays the same glyphs on the display's plane. See the README.

From the fork by Noah Teetz:

• Latin-1 letters, German and English quotation marks and the euro sign in the text sheets; accented letters used to vanish without an error.
• theme.yml can name a typeface of its own, pixel faces included; without it nothing changes.
• Item icons at 48 units.
• Files under plugins/VoidRpUI/pack/ go into the resource pack as they are.

Also:

• The aim is read 60 times a second whatever input.frame-rate says; that now only limits a pointer sent frame by frame.
• input.client-clock-offset (0.9) and /vui debug offset, /vui debug motion to compare the two kinds of pointer live.
