Chest Loot Modifier

About

Minecraft mod for modifying the items that appear in chests in Minecraft

Everytime a chest is generated in the world, it is not until the chest is opened for the first time that loot for it is generated. Therefore, this mod does not require the game to be restarted for the changes in the config file to take effect. However, once a chest is opened for the first time, the loot generated for said chest will not change unless there is a mod that regenerates the loot for the chest.

Configuration

A file named chestlootmodifier_config.json needs to exist on the config folder of the Minecraft instance that the mod is loaded on. The mod will automatically create a template for this file during initialization if the file doesn't exist. That means that if the file gets corrupted, you can always delete it and the mod will re-create a template for it.

A sample file looks like this:

{
  "LoadPoolsAtRuntime": false,
  "Names": {
    "Common": {
      "MinRolls": 1,
      "MaxRolls": 2
    },
    "Uncommon": {
      "MinRolls": 1,
      "MaxRolls": 2
    },
    "Rare": {
      "MinRolls": 1,
      "MaxRolls": 3
    },
    "SuperRare": {
      "MinRolls": 2,
      "MaxRolls": 4
    }
  },

  "ChestDefinitions": {
    "Common": ["minecraft:chests/spawn_bonus_chest", "minecraft:chests/village/village_mason", "minecraft:chests/simple_dungeon"],
    "Uncommon": ["minecraft:chests/desert_pyramid", "minecraft:chests/pillager_outpost", "minecraft:chests/ruined_portal"],
    "Rare": ["minecraft:chests/bastion_treasure", "minecraft:chests/stronghold_library"],
    "SuperRare": ["minecraft:chests/woodland_mansion", "minecraft:chests/end_city_treasure"]
  },

  "LootDefinitions": {
    "Common": ["minecraft:golden_sword(1)(1)", "minecraft:golden_pickaxe(1)(1)", "minecraft:diamond(16)(3)"],
    "Uncommon": ["minecraft:diamond(8)(4)", "minecraft:diamond_sword(1)(1)"],
    "Rare": ["minecraft:netherite_axe(1)(3)", "minecraft:netherite_ingot(8)(1)"],
    "SuperRare": ["minecraft:elytra(1)(2)", "minecraft:shulker_box(2)(5)"]
  }
}

LoadPoolsAtRuntime - decides whether the pools are loaded when Loot Table Loading happens for the world or whether to load them when a chest is opened for the first time. Default value is false which means the pools are loaded when the world is loaded. Being false might make the mod compatible with other mods. Making it true might make the mod incompatible with other mods.

Names are the names used to identify the kind of loot. This can be anything, but whatever they are, they must be the same on ChestDefinitions and LootDefinitions.

• MinRolls and MaxRolls are the number of rolls to do for that rarity pool. Choosing a minimum of 0 will give it a chance that none of the items in that pool will appear. These numbers are integers. Because it is a range between min and max, the rolls for the pool will be a random number between the range.

ChestDefinitions these are the chests that will apply to a loot. For instance, which chests will get Common, Uncommon, Rare, and SuperRare loot. These must be the fully qualified Minecraft Identifiers for the chests.

LootDefinition these are which items will apply to each type of loot. For instance, which items will apply to Common loot, Uncommon loot, etc.

• The number in the first parenthesis is the number that will indicate the number of items to appear if the item is selected to appear on the chest that the rarity applies to.

• The number in the second parenthesis is the weight for the item. The higher the weight, the higher the chances that such item will appear should the pool be selected for the chest.

Issues

The mod has a lot of logic to print to the console when something fails. If the game crashes or if the loot doesn't seem to have been applied to the chests, create an issue.
