Magic Cracker Factory

 

This mod adds ComputerCraft peripherals that provide powerful creation and management features for Minecraft server admins.  None of the items in this mod are craft-able and are meant to be acquired in creative mode.  Recipe mods can be used to create recipes of items if the server admin desires.

ComputerCraft Peripherals

Cartographer

The Cartographer peripheral is used to manipulate maps.  This can be used to create custom maps and images. 

Remote Receiver

The Remove Receiver peripheral is used to listen to the remote control's signals in the world making it possible for blocks in the world to be point and clickable.  Also listens for touch events on touch buttons and map guards.  Together with the cartographer this can be a useful means to make interface displays from wall maps.

Sentinel

The Sentinel peripheral is used to have greater control over sensitive areas.  Nullify player block breaking and placing, explosions, mob spawns, and endermen teleports.  Bounds are created as cuboid shapes, cylindrical shapes or boundless(anywhere).

Terraformer

The Terraformer peripheral is used to manipulate world biome data.  This can be used to change the biomes in the world.

Web Modem

The Web Modem is used to turn your computercraft computer into a web server that can be accessed from the real world.  This is useful for driving events on a Minecraft server from a web interface, getting information from the Minecraft server on the web, or establishing a datalink between 2 or more Minecraft servers.  This peripheral was adapted from a mod written by qidydl as part of his unreleased experimental ComputerCraft-Webserver mod for 1.6.4.

Items

Universal Remote

Use of this item causes a remote_control event to be generated in any connected Remote Receivers.  A raytrace is done from the player to whatever block was clicked on and a precise hitpoint is relayed to the server.  The event conveys the player's identity, the position of the block clicked on, the point on the block that was hit and the id of the remote.  Remotes can be configured with custom ids for specific applications. The orb on the icon of the remote can be customized to any color per remote for easy identification.

Map Guard

The map guard is used to place an invisible shield block over an item frame to prevent the contained item or map from being broken, spun, or removed.  This guard is touch sensitive and will generate touch_map events that can be picked up by the Remote Receiver.  The map guard also comes in a lighted version so a map can be uniformly lit in a dark room.

Light

Freely place-able invisible source light blocks like those provided in later versions of Minecraft.  Available from 1-15 light levels for lighting up those dark areas in a much more efficient and subtle manner.  Behaves as air and can be blocked over to eliminate it.

Command Potion

A potion that has an embedded custom command.  Consuming the potion is the same as running the command by hand therefor embedded commands with a privilege level higher than the player consuming the potion won't run.  Use with the /prox command with a Remote Receiver listening for proxy events to create custom behavior at the server level.  Ideally with a generated token as part of the command for authentication.  The color of the potion can also be customized.

/give @p mcf:commandpotion 1 0 {label:"Dawn Potion",command:"/time set 0",color:"#FFFF20",info:"Sets time to morning"}

Entities

Item Display Entity

This entity can be summoned from the commandline to display items anywhere in free space.  Very useful for decorating.  These items can't be interacted with directly.Summon a diamond at coordinates in the world.

If a Map Guard is placed in the block that is occupied by an Item Display Entity it will wrap around it and make it touch sensitive.

What's it good for?

In-Game Interactive Biome Map

Map program

    I wanted an Amidst-like program that could be used in a multiplayer server.  I used the TerraFormer to pull biome ids from the world.  I then mapped these biome ids to colors and streamed them to common vanilla maps with the Cartographer.  The blue targets around the map are used to move the map around and zoom in/out by clicking them with the Universal Remote at a distance.  The Remote Receiver gathers these click events and updates the display.  By clicking on the map you are told the coordinates and the biome name via direct chat(only the clicking player sees the chat).  This is all driven by a ComputerCraft command computer.  The performance is pretty decent.  The biome information is pulled from Minecraft's functions directly so it doesn't matter if you're using modded biomes like from Biomes O'Plenty.  The areas can be scanned regardless of whether they've been visited or not.

Interserver Block Mapping and Transfer

    When moving from 1.7.10 to 1.12.2 there were plenty of modded blocks that didn't make the update whether for block ids changing names or just dropped completely.  I ran the 1.7.10 server and the 1.12.2 server at the same time and connected them via a network link.  I used a standard command computer in 1.7.10 and transmitted the world's block information via the regular http methods.  On the 1.12.2 server I ran a command computer with an attached WebModem peripheral to receive the information being sent from the 1.7.10 server's command computer.  I created a translation table in Lua on the 1.12.2 server and placed the blocks in the world at the coordinates.  Since the map generation between 1.7.10 and 1.12.2 was unchanged I as able to save our beloved old structures and put them right where they belong on the new 1.12.2 server.

  This method of transferring information between servers with the WebModem can be used for interserver build collaborations, imaginative games, or just transferring builds and messages.

Other Ideas

• Pull images from the web and transfer the pixels to a minecraft map with the Cartographer
• Make interactive touch displays driven with the Remote Receiver and Cartographer
• Set and display claims on a world map in a friendly multiplayer server
• Drive a villager shop from a website with php/sql to control sold items and their prices with the WebModem
• Use a remote to identify a location for a ComputerCraft script to build a structure, erase a chunk, place mob spawning bounds etc.
• Use touch buttons for identity based access into server vaults and prisons.
• Use Command Potions with the proxy command to provide token based admin-like commands to survival players. Such as changing the time of day.
• Link real world Apache/PHP server with a gameworld WebModem peripheral and create maps of the world on the web.

Frequenty Asked Questions

Q: Will you port this to a newer/older version of Minecraft?

A: No. I currently have no intention of porting this to any other version of Minecraft.  Please be respectful of this and refrain from bombarding the comments section with this often asked and ignored request.
