Minecraft servers with plugin HolographicDisplays

## 🔌 About Holographic Displays Holographic Displays is a Minecraft plugin that provides persistent floating holograms which can display text and items. The plugin exposes in-game commands for creating and editing holograms and offers a developer API to integrate holograms into other plugins. ## 🎯 Purpose The plugin solves the need to display floating information, labels, menus, and visuals in the world without creating permanent visible entities. It is useful for server administration, cosmetic displays, in-world menus, and integrations where plugins need to present data to players at fixed locations. ## ⚙️ Features - Create and remove named holograms at specific locations. - Add, remove, set, and insert text lines for holograms. - Display floating items as hologram lines (floating item support). - Read lines from a text file into a hologram. - Read and render images into a hologram from a file or URL (with configurable symbol mapping and max width). - Align, move, copy, and teleport to holograms. - Reload plugin configuration and saved holograms without manual file edits. - Developer API available for other plugins to create and manage holograms programmatically. ## 🧩 Who It Is For - Server administrators who want visual in-world displays (SMP, Survival, Minigame servers). - Plugin developers that need an API to present text/items to players in the world. - Staff teams that use holograms for signs, menus, or informational displays. ## 🏗️ Example Use Cases - A minigame shows current scores above each arena using holograms. - A server lobby displays server rules and click-to-teleport items as floating lines. - A plugin integration posts dynamic player stats to a hologram at a fixed location. ## ⌨️ Commands | **Command** | **Description** | **Permission** | **Access** | |---|---|---:|:---| | `/hd` | Main command; shows plugin info and version. | none (accessible to all) | Player | | `/hd help` | Shows available commands and brief help. | none (accessible to all) | Player | | `/hd create <hologramName> [text]` | Create a new hologram at your location. | `holographicdisplays.create` | Admin | | `/hd delete <hologram>` | Delete a named hologram. | `holographicdisplays.delete` | Admin | | `/hd list [page]` | List existing holograms and locations. | `holographicdisplays.list` | Admin | | `/hd near <radius>` | List holograms near you within radius. | `holographicdisplays.near` | Admin | | `/hd teleport <hologram>` | Teleport to a hologram location. | `holographicdisplays.teleport` | Admin | | `/hd align <axis> <hologram> <reference>` | Align one hologram to another on specified axis. | `holographicdisplays.align` | Admin | | `/hd movehere <hologram>` | Move a hologram to your feet position. | `holographicdisplays.movehere` | Admin | | `/hd edit <hologram>` | Enter edit options for a hologram. | `holographicdisplays.edit` | Admin | | `/hd addline <hologram> <text>` | Add a text line to a hologram. | `holographicdisplays.addline` | Admin | | `/hd removeline <hologram> <number>` | Remove a numbered line from a hologram. | `holographicdisplays.removeline` | Admin | | `/hd setline <hologram> <number> <newText>` | Change a specific line's text. | `holographicdisplays.setline` | Admin | | `/hd insertline <hologram> <number> <text>` | Insert a line after the given index. | `holographicdisplays.insertline` | Admin | | `/hd info <hologram>` | Print hologram contents with line numbers. | `holographicdisplays.info` | Admin | | `/hd copy <from> <to>` | Copy contents from one hologram to another. | `holographicdisplays.copy` | Admin | | `/hd readtext <hologram> <file>` | Read lines from a file into a hologram. | `holographicdisplays.readtext` | Admin | | `/hd readimage <hologram> <image> <width> [-a]` | Render an image into the hologram from file or URL. | `holographicdisplays.readimage` | Admin | | `/hd reload` | Reload configuration and saved holograms. | `holographicdisplays.reload` | Admin | Note: the documentation states each subcommand has an individual permission (for example `/hd list` requires `holographicdisplays.list`). The main `/hd` command is accessible to everyone. ## 🔐 Permissions | **Permission** | **Description** | **Default** | |---|---|---:| | `holographicdisplays.<subcommand>` | Individual permission for each `/hd` subcommand (example: `holographicdisplays.list`). | not specified | | `holographicdisplays.update` | Receive update notifications on join if enabled in configuration. | not specified | | `holographicdisplays.*` | Grants all holographicdisplays permissions (if supported by the permissions plugin). | not specified | ## ⚙️ Installation ### 📥 Setup - Download the official plugin JAR from a trusted catalog. - Place the JAR into the server `plugins/` directory for Bukkit/Spigot. - Restart the server and check the console to confirm the plugin loaded. ### 📦 Dependencies - No required dependencies are listed in the official documentation summary; verify the download page for any optional integrations when installing. ### 🧾 Configuration - The plugin supports configuration files and saved holograms; use the provided reload command to apply changes after editing files. - Image rendering and symbol mapping are configurable via the plugin configuration. ## 🧠 Technical Notes - Official documentation includes an upgrade guide for Minecraft 1.13+ regarding material name changes and image/icon handling. - A developer API is documented for plugin integrations. ## 🤝 When This Plugin Is Useful If you need persistent, editable in-world displays for information, menus, or plugin integrations, Holographic Displays provides named holograms, file/image import, and an API so other plugins can create and update holograms reliably.
