Utilities: Holograms

Currently holograms are just packet blobs sent to 1.8 clients, to support our existing functionality in spawn tutorial, team respawn and some Limbo games.

Making holograms

To create a basic hologram:

/holo set "<text>"

It will create a hologram where you stand. The <text> parameter supports formatting codes (&a, &o, etc). You can also make multiple lines like this:

/holo set "First line<N>Second line"

Sometimes it’s necessary to name a hologram, to edit it later with Command Blocks or other plugins. In that case, use additional parameter:

/holo set <id> "<text>"

Example: /holo set spawn1 "&aWelcome to Flatcore!"

If a hologram spawn1 doesn’t exist, it will be created. If it exists however, you will overwrite its text with new value.

The /holo set command writes data to disk.

Updating holograms

If you just want to update a hologram without saving the data permanently, you can use:

/holo update <id> "<text>"

The <text> parameter supports multiple lines, example: /holo update spawn1 "&aWelcome to Flatcore<N>&aHardcore Survival Server"

You can also update just one line:

/holo updateline <id> <line> "<text>"

Moreover, if you pass empty string to <text> it will hide that particular line.

/holo updateline <id> <line> ""

Both commands require the <id> parameter.

Deleting holograms

To remove the nearest hologram:

/holo remove

To remove a specific hologram:

/holo remove <id>

Hiding or showing

You can hide a hologram with following:

/holo hide <id>

If you want the state to persist in YAML, use:

/holo hide <id> p

Same with showing, just replace the parameter with show:

/holo show <id>
/holo show <id> p
