Pink Iron

Spoiler

Pink Iron Ingot

Pink Iron is a material added for the Love Golem. It is used for repairing and building the Love Golem.

Pink Iron Ingot

The Pink Iron Ingot is the basic Pink Iron material.

Features

  • Can be used to repair damaged Love Golems.
  • One Pink Iron Ingot restores 25 health to a Love Golem.
  • Can be crafted from 1 Iron Ingot + 1 Pink Dye.
  • Can be smelted back into a normal Iron Ingot.

Recipe

Iron Ingot + Pink Dye → Pink Iron Ingot

Pink Iron Ingot Recipe

This is a shapeless crafting recipe, so the two ingredients can be placed anywhere in the crafting grid.


Pink Block of Iron

The Pink Block of Iron is the block of Pink Iron material.

Features

  • Is used as the main building material for the Love Golem.
  • Can be crafted from 9 Pink Iron Ingots.
  • Can also be created by combining 1 Iron Block + 1 Pink Dye.
  • Can be smelted back into a normal Iron Block.

Recipe

9 Pink Iron Ingots → Pink Block of Iron

Pink Block of Iron Recipe

or:

Iron Block + Pink Dye → Pink Block of Iron

Pink Block of Iron Recipe

The block can be converted back into normal iron by smelting:

Pink Block of Iron → Iron Block

Love Golem Repair

Pink Iron is the special repair material for the Love Golem.

  • 1 Pink Iron Ingot = +25 health
  • Normal Iron Ingots do not repair Love Golems.
  • Pink Iron therefore gives the Love Golem its own repair material.

Sharing & Caring

Spoiler

Sharing Effect Items

Sharing is a mob effect inspired by the 15w14a Potion of Sharing.

The effect is intended for mobs, not players.

A mob affected by Sharing can give random useful items.

Sharing Loot

The possible drops include:

  • Bread
  • Coal
  • Diamonds
  • Gold Ingots
  • Iron Ingots
  • Lapis Lazuli
  • Melon Seeds
  • Pumpkin Seeds
  • Redstone
  • Saddles

Sharing does not affect players

Players cannot receive the Sharing effect.

It is intended effect that can be given only to mobs.

Sharing is available as:

  • Potion of Sharing
  • Long Potion of Sharing
  • Splash Potion of Sharing
  • Long Splash Potion of Sharing
  • Lingering Potion of Sharing
  • Long Lingering Potion of Sharing
  • Arrow of Sharing
  • Long Arrow of Sharing

Brewing

Awkward Potion + Golden Apple → Potion of Sharing

Its duration can then be increased using redstone:

Potion of Sharing + Redstone → Long Potion of Sharing

Splash and Lingering versions use the normal Minecraft potion conversion.

Arrows with Sharing effect are made using the normal Minecraft recipe with the Lingering Potion.


Caring Effect Items

Caring is another mob effect inspired by 15w14a, with a bit of modification.

Instead of simply making mobs approach other mobs, Caring makes affected mobs actually try to attack them.

The effect is designed for mobs and does not work on players.

Caring Targeting

When a mob has Caring:

  • It searches for suitable targets in approximately a 16-block radius.
  • Caring can detect mobs even when they are behind walls.
  • A wall does not prevent the mob from selecting a target.
  • The mob still needs to be able to physically reach the target.
  • Navigation attempts to find a route around obstacles instead of simply walking into a wall.
  • Mobs that are underground or unreachable are not kept as permanent targets.
  • If no valid target is nearby, the mob returns to its normal behavior.
  • If a target later enters the detection range, Caring effect takes control again.

Current Target

Once a Caring mob starts fighting a target:

  • It keeps that target until the target is killed, whenever possible.
  • It does not switch between nearby mobs during an active fight.
  • After killing its target, it searches for another target.
  • If the mob does not successfully hit its current target for 15 seconds, the target can be abandoned and another target selected.
  • The 15-second timer is based on failing to successfully hit the target.

This allows Caring mobs to navigate around walls and obstacles without randomly abandoning a target because the route takes time.

Current Target


Caring and Passive Mobs

Caring can be given to normally peaceful mobs.

Examples include:

  • Cow
  • Pig
  • Sheep
  • Chicken
  • Ocelot
  • Allay
  • Villager
  • Other non-hostile mobs

When these mobs have a target, Caring takes priority over their ordinary behavior so they can efficiently move toward and attack their target.

When there is no target, the mob returns to its normal behavior.

Movement

Passive mobs using Caring have a slightly faster movement speed.

Villagers retain their normal movement, preventing Caring from making them appear to have a something like Speed effect.


Iron Golems and Love Golems

Iron Golems and Love Golems cannot receive Sharing or Caring.

However, they are still valid targets.

For example:

  • A Pig with Caring can attack an Iron Golem.
  • A Cow with Caring can attack a Love Golem.
  • A Villager with Caring can attack an Iron Golem.
  • The Iron Golem or Love Golem can react to being attacked normally.

This means the golems are protected from having Caring override their own AI, but they are not protected from Caring mobs attacking them.


Caring is available as:

  • Potion of Caring
  • Long Potion of Caring
  • Splash Potion of Caring
  • Long Splash Potion of Caring
  • Lingering Potion of Caring
  • Long Lingering Potion of Caring
  • Arrow of Caring
  • Long Arrow of Caring

Brewing

Awkward Potion + Brown Mushroom → Potion of Caring

Its duration can then be increased using redstone:

Potion of Caring + Redstone → Long Potion of Caring

Splash and Lingering versions use the normal Minecraft potion conversion.

Arrows with Caring effect are made using the normal Minecraft recipe with the Lingering Potion.

Frequently Asked Questions

Will the mod be available for Forge, and will it be backported to newer Minecraft versions?

Yes, I plan to release the mod for Forge. The main goal of this mod is to bring the content and features of the 15w14a snapshot to newer versions of Minecraft, while keeping the original feel as close to the original as possible.

When will the next update drop?

I'll try to work on the mod as much as I can in my free time, but keep in mind that I'm a solo developer working on this project. This is currently my first and only mod, so most of my work will be focused on it. Updates will mainly focus on fixing bugs, and making the mod as accurate to the original 15w14a snapshot as possible.
