Holograms

A hologram is a stack of lines standing at one place. Its location is the bottom of the last line; the lines stack upwards from there. Each line is text, a floating item, a floating block or a player head, and each can carry line tags that style it alone.

Creating one

A hologram created in game stands spawn-height blocks (default 2.0) above your feet, turned to face you, with the default-view-distance of config.yml (default 48). A preset's lines replace %hologram% with the new name. See Configuration to add presets.

The shipped presets:

A name is lowercase letters, digits, _ and -, up to 32 characters, and unique among holograms.

The editor

/holo <name> (or a left-click in the list) opens the hologram's editor:

The windows are ExyliaLib dialog windows: every field of a section in one window, saved together. On a client older than 1.21.6, or on Bedrock, the same fields arrive through chat or a form.

Lines

The lines screen shows the page you are on:

The book in the middle moves between pages.

From commands, line numbers start at 1:

/holo spawn addline {letters}A new bottom line
/holo spawn insertline 1 <size:2>{primary}&lA new top line
/holo spawn setline 2 {letters}Changed
/holo spawn moveline 3 1
/holo spawn removeline 4
/holo spawn line 1 size 2.4
/holo spawn line 1 shine on
/holo spawn line 1 shine reset

/holo <name> line <n> <tag> [value] changes one tag and keeps the rest of the line. The tags are text, size, head, opacity, background, shadow, glow, spin, bob, pulse, typewriter, shine, flow, range, permission and condition. No value, or reset, takes the tag off; on gives a motion tag its default; glow team is the team colour; shadow reads true/false, on/off, yes/no.

Appearance

These apply to the whole hologram; a line tag overrides them for one line.

Location and facing

Facing only shows on a fixed billboard (or the axis a vertical or horizontal one keeps). Turning a center hologram — rotate, face, or a new yaw in the location window — switches it to fixed, since a centred hologram would turn back to every viewer.

A hologram whose world is not loaded waits and appears when the world loads.

Copies, renames and deletion

• /holo <name> clone <copy> makes a copy at the same place, on top of the original. Move one of them afterwards.
• /holo <name> rename <new> keeps its place in the file.
• /holo <name> delete asks in a window for a player; from the console it deletes at once.
• /holo <name> disable keeps it in the file without showing it; enable shows it again.

Finding holograms

• /holoadmin (or /holoadmin list) opens the list for a player; the console gets one line each.
• /holoadmin near [radius] lists the holograms around you, nearest first, each with a click to edit it or go there. The default radius is near-radius (20 blocks).
• /holo <name> info prints its details and every line, numbered page.line when it has pages.
