MapVNC - Your VNC Client, inside Minecraft

MapVNC is a powerful plugin that brings a fully interactive VNC client directly into the game world. Using the robust MapEngine API, it renders a remote desktop onto a dynamic grid of in-game maps, allowing players to view and control a remote computer from within Minecraft.

Whether for server administration, remote monitoring, or just for fun, MapVNC provides a seamless and unique integration between Minecraft and any VNC-enabled machine.

Features

• Dynamic Display Creation: Create VNC screens of any size, anywhere in the world.
• Real-Time Rendering: View a remote desktop with configurable color depth for performance tuning.
• Full Interactivity:
  • Mouse Control: Point and click on the maps to control the remote cursor.
  • Mouse Dragging: A sneak-based system to simulate clicking and dragging.
  • Text Input: Type text directly into the remote session via commands.
  • Key Presses: Send special key events like Enter, Shift, and Escape.
• In-Game Management: Easily move, resize, and remove VNC displays without restarting.
• Proximity-Based Rendering: Displays are only rendered for nearby players to ensure optimal server performance.
• Quick Target Selector: Use -1 as an ID to automatically target the nearest screen.
• Detailed Permission System: Fine-grained control over who can create, manage, and interact with displays.
• User-Friendly Commands: Intuitive commands with rich tab-completion to guide users.

Prerequisites

• Server Software: Paper, Spigot, or a compatible fork (1.21+ recommended).
• Java: Java 21 or higher.
• Dependency: MapEngine 1.8.10+ is a required dependency. MapVNC will not start without it.

Installation

1. Ensure you have MapEngine 1.8.10+ installed on your server.
2. Download the latest MapVNC-*-all.jar file from the "Versions" tab.
3. Place the downloaded JAR file into your server's plugins directory.
4. Restart or reload your server.

Commands & Usage

The main command is /mapvnc, which can be shortened to /mvnc.

Targeting the Nearest Screen

For convenience, you don't always need to know a display's specific ID. For any command that requires an <id>, you can use -1 as a special placeholder.

When you use -1, the plugin will automatically find and target the nearest VNC display within a 16-block radius of your location. The distance is measured from the display's anchor point (its top-left corner).

Example: Stand near a screen and type /mvnc connect -1 to connect it, without ever needing to run /mvnc list.

This feature works for: remove, set, connect, disconnect, input, and key.

Mouse Dragging

You can simulate clicking and dragging (e.g., to select text or move a window) with a special sneak-based mechanic:

1. Aim at the spot on the map where you want to start the drag.
2. Hold down your Sneak key (L-SHIFT by default).
3. While still sneaking, Left-Click on the map. A "Mouse Down" event is sent, and an ActionBar message will appear confirming you are in dragging mode.
4. To move the mouse while dragging, simply click on other parts of the map. You must remain in sneak mode.
5. When you are finished, Release the Sneak key. This sends the "Mouse Up" event, completing the drag operation.
