There are currently no plans of updating this to future Minecraft versions.

This mod was originally made for ZeekDaGeek's FTB Departed Hardcore Subserver because we wanted a chance to get back in after dieing while still keeping the hardcore experience and having deaths be painful. It was made completely server-side-only so that players wouldn't need to install any additional mods. It turned out to be fun having to send rescue teams to retrieve the player head from dead player corpses, so I fleshed the mod out and made it fully configurable. Hopefully this will make having Hardcore servers more viable.

Features

Server-side only - no need to have it on clients
Highly customizable - define ritual structure as well as costs and penalties
Locate player corpses by burning a specific (configurable) item named after them
Player Head spawns below the ground on death (necessary for the revival ritual)
Revival Instruction Book when a player dies
Debugging Tools for configuring a ritual: /hardcorerevival spawnritual and /hardcorerevival debug

Custom Ritual Structures

Ritual structures are defined in .json files. See Goldman.json for the default structure, which is two gold blocks with the head on top, activated by a golden apple.

Detailed description:

mappings: JSON object containing a character->block mapping. The keys of this object MUST be one character long and 'H' is reserved for the player head, so don't define it here. For ore dictionary names, use the prefix "ore:". Also supports "any" and "solid".

structure: JSON array containing one JSON array per y-layer of the structure. The inner array contains a string for every z-line, and each character in that string represents one block (character position defines x) based on the mapping defined in mappings

consumeStructure: same as structure, but only allows 1 and 0 - defines what blocks of the ritual should be consumed upon activation (1 = consume)

activationItem: a string defining the item used to activate the ritual; format: <stacksize>x<item>@<metadata>

activationItemNBT: a string representing Jsonified NBT data (same format as in /give command) to be used as NBT data for the activation item

activationItemHelpText: a string that will appear in the help book on the Activation Item page

structureHelpText: one or multiple strings that will appear in the help book on the Structure page (each string is one page)
