Advanced Memory Card

An Applied Energistics 2 (AE2) add-on mod that supercharges the AE2 Memory Card with two major features: bulk configuration copying and advanced P2P tunnel management.

🌟 Features

🔧 Two Working Modes

The mod stores its state as a "mode" inside the item's NBT, and you can switch between them at any time:

Mode	Description
Copy Mode	Select a region and paste a copied AE2 device configuration onto every AE2 block and part inside it at once
Config Mode (P2P Tunnel Config)	Right-click a P2P tunnel part to open a GUI for centrally managing and configuring P2P tunnels within the network

📋 Copy Mode

• Bulk region copy: Copy a single AE2 device's configuration first, then select two opposite corner blocks to define a region, and right-click on air to apply the config in bulk.
• Supports AE2 blocks and parts: Every AEBaseBlockEntity (ME controllers, interfaces, storage buses, etc.) and every part on an IPartHost within the region is processed.
• Volume limit protection: If the region volume exceeds the server config maxCopyVolume (default 2048 blocks), the paste is rejected with a message to prevent accidental oversized selections and lag.
• Visual selection box: The selection is color-coded in real time (red = pick first point / white = pick second point / green = ready to paste), with distinct colors for the targeted block and out-of-range blocks.
• Real-time feedback: The item tooltip and chat bar display marked coordinates, region size, and the number of blocks pasted.

🕸 Config Mode (P2P Tunnel Config)

Right-click any P2P tunnel part to open the configuration GUI and visually manage all P2P devices in the current AE network:

• P2P tree list: Automatically scans the network and displays all P2P devices grouped by type / channel, with expand/collapse and search filtering.
• Detail panel: Selecting a node shows its type, frequency, input/output role, connection status, and more.
• Rename / alias: Set a custom name for an individual P2P device, or set an alias for an entire channel (the channel's input side) for easy identification.
• Bind frequency: Bind the selected P2P to a specific 4-digit hexadecimal frequency (e.g. 0A1B). Non-ME P2Ps automatically and intelligently determine their input/output role.
• Assign new channel: Assign a brand-new free frequency to the selected non-ME P2P and set it as the input side with one click.
• Auto-configure input/output (ME P2P only): Automatically decides whether an ME P2P should act as input or output based on whether its external network is connected to an ME Controller, and assigns a frequency automatically.
• Highlight & locate: Highlights P2P tunnels in the world (self / input / output rendered in different colors), optionally auto-turns your head toward the target, and sends location info and a teleport link to the chat bar.
• Cross-dimension connections: Fixes the vanilla issue where the client only sent coordinates, making cross-dimension P2Ps impossible to locate. The encoding now carries dimension info, allowing P2P devices to be correctly located and highlighted across dimensions.

⌨️ Mode Switching

• V key (default, rebindable in the game's Controls settings) — press while holding the Advanced Memory Card to switch modes.
• Shift + Right-click — quickly switch between the two modes (in Copy Mode, Shift + Right-click performs the native AE2 copy action instead of switching).

📦 Installation

Requirements

Dependency	Version
Minecraft	1.20.1
Forge	47.4.10 or higher (loader range [47,))
Applied Energistics 2 (AE2)	15.4.10 or higher ([15.4.10,))
mixinextras	1.0.0+ (optional, for Mixin enhancements)

The mod also depends on Jade, GuideME, and JEI at runtime (common AE2-ecosystem add-ons; installing them is recommended for the best experience).

Steps

1. Download the latest advanced_memory_card-<version>.jar from the releases page.
2. Place the .jar file into your Minecraft mods folder.
3. Make sure the required mods above are installed.
4. Launch the game and find the item under the "Advanced Memory Card" creative tab.

🛠 Configuration

The mod provides both client and server config files (located in the config/ directory):

Server config (advanced_memory_card-server.toml)

Option	Default	Description
maxCopyVolume	2048	Maximum region volume (block count) allowed in Copy Mode; larger selections are rejected
sendHighlightToChat	true	Whether to send location info and a teleport link to chat when highlighting a P2P device

Client config (advanced_memory_card-client.toml)

Mainly used to personalize UI and rendering appearance. You can adjust:

• Highlight behavior: rotateHeadOnHighlight (auto-turn head when highlighting), p2pHighlightDurationSec (highlight duration, 1–60 seconds).
• P2P tree widget: background / selected / hover colors, indent, row height, icon spacing, channel warning threshold, max name length, etc.
• Detail panel: background, title, label, value, and status (not active / not connected / connected) colors and layout dimensions.
• Generic buttons (FlatButton): default / hover / pressed / text colors.
• Copy Mode selection box: colors for start point, end point, targeted point, out-of-range, and the three selection states.
• P2P highlight rendering: self / input / output colors.
• Item color: item base color and tint color.

All colors are hexadecimal values (ARGB for GUI classes, RGB for rendering classes) and can be edited directly in the config files.

📖 Quick Usage Guide

Copy Mode

1. Hold the Advanced Memory Card in Copy Mode and Shift + Right-click a source AE2 device to copy its configuration.
2. Right-click the first corner block to mark the start point (red).
3. Right-click the opposite corner block to mark the end point (white); it now enters the ready-to-paste state (green).
4. Right-click on air to apply the config in bulk to all AE2 devices in the region.

Config Mode

1. Switch to Config Mode and right-click any P2P tunnel part to open the configuration GUI.
2. Browse / search the network's P2Ps in the left tree, and select a node to view its details on the right.
3. Use the detail panel buttons to rename, bind a frequency, assign a new channel, auto-configure input/output, highlight & locate, and more.
