Yet Another MC BINGO

Appearance

Custom Objectives ​

By default, any advancement or item in the game can be used directly in a tier list.

However, you might want a particular item or objective to have different behavior when it appears on a card. This includes requiring specific NBT data, a certain quantity of an item, multiple items at once, and so on.

To achieve this, you can place custom .json objectives in a datapack, under data / <namespace> / yet-another-minecraft-bingo / objectives / <path>.json.

Example ​

json
{
  "type": "item",
  "display": {
    "name": "Get Sticks"
  },
  "item": "minecraft:stick",
  "count": 3
}
json
{
  "S": [],
  "A": [],
  "B": [],
  "C": [],
  "D": [
    "mynamespace:get_three_sticks"
  ]
}

To see more examples, the built in "challenge" objectives can be used as a reference - which are included in challenge.tierlist.json.

Objective JSON ​

These are common properties that can be specified on any objective:

  • "type": "...": The type of objective: item, one_of, all_of, inverse, or opponent.
  • "display": {}: Alters what name or item the objective shows when displayed on the card
    • "name": {"text": "Kelp!"}: Uses raw JSON text format to specify the objective name
    • "item": "minecraft:kelp": Changes the visual item for the objective
    • "itemNbt": "{}": Sets pre-1.20.6 NBT data on the item
    • "itemComponents": {}: Sets post-1.20.6 JSON-encoded data components on the item
      • "minecraft:enchantments": {"levels":{"mending":1}}
    • "image": "mynamespace:myimage": References a custom PNG image to be used as the objective icon
    • "decoration": "NONE": Applies a decoration to the objective's tile on the card. One of: ADVANCEMENT, MULTI_ITEM, FORBIDDEN, NONE.
  • "conflictsWith: ["minecraft:dried_kelp"]: A list of conflicting objectives that should never appear on the same card as this one.

Items ​

Tracks when an item enters the player's inventory.

  • "type": "item"
  • "item": "minecraft:kelp": The item that the player needs to pick up for this objective
  • "count": <number-source>: The amount of this item that the player needs to obtain
  • "nbt": "{}": Sets pre-1.20.6 NBT data on the item
  • "components": {}: Sets post-1.20.6 JSON-encoded data components on the item
    • "minecraft:enchantments": {"levels":{"mending":1}}
  • "permanent": false: Whether the objective is permanently scored once obtained. If true, the objective will remain scored even if Inventory mode is enabled.

Advancements ​

Tracks when a player scores an advancement. This is mainly useful for modifying the objective's "display" properties.

  • "type": "advancement"
  • "advancement": "minecraft:story/mine_stone": The advancement identifier that should capture the objective when obtained.

Statistics ​

Tracks a player's statistics.

  • "type": "stats"
  • "statType": "minecraft:custom: Specifies the statistic type.
  • "statName": "minecraft:open_barrel": The statistic name. Optional - if omitted, uses the sum of all statistics under the type.
  • "min": <number-source>: The minimum statistic value required to earn this objective (default: 1)
  • "max": <number-source>: The maximum statistic value required to keep this objective (default: unset)

Scoreboard Objectives ​

Tracks a particular scoreboard entry for each player. This may be useful for more complicated goals that need their own logic written in a datapack.

  • "type": "scoreboard"
  • "scoreboardName": "your_datapack_objective": The name of the scoreboard objective that should be tracked.
  • "min": <number-source>: The minimum scoreboard value required to earn this objective (default: 1)
  • "max": <number-source>: The maximum scoreboard value required to keep this objective (default: unset)
  • "relative": false: Measures the increase in this scoreboard since the start of the game, rather than its actual value. (default: false)
  • "permanent": false: Whether the objective is permanently scored once obtained.

INFO

If your scoreboard represents a statistic/counter, using "relative": true means that you can avoid resetting its value when the game starts. The game will track its change in value automatically.

Otherwise, you should use the on_playing function tag to reset all scoreboard values at the start of the game.

One Of ... ​

Tracks if a player obtains any of the listed objectives.

  • "type": "one_of"
  • "objectives": ["minecraft:kelp", "minecraft:dried_kelp"]: A list of objective IDs. The player may obtain any of these to complete this objective.
  • "permanent": false: Whether the objective is permanently scored once obtained. If true, the objective will remain scored even if Inventory mode is enabled.

All Of ... ​

Tracks if a player has obtained all the listed objectives.

  • "type": "all_of"
  • "objectives": ["minecraft:kelp", "minecraft:dried_kelp"]: A list of objective IDs. The player must obtain all of these to complete this objective.
  • "permanent": false: Whether the objective is permanently scored once obtained. If true, the objective will remain scored even if Inventory mode is enabled.

Inverse / Never Obtain ... ​

Tracks if a player has never obtained an objective. For example, this goal will be taken away if a player picks up wheat seeds at any point.

  • "type": "inverse"
  • "objective": "minecraft:wheat_seeds": The objective that should be inverted.
  • "permanent": true: Whether the objective is permanently scored once obtained. If false, this objective can be re-gained by dropping the wheat_seeds.

Opponent Obtains ... ​

Tracks if any opposing team obtains an objective. For example, when a team obtains wheat seeds, every other team will capture this objective.

  • "type": "opponent"
  • "objective": "minecraft:wheat_seeds": The objective that should be tracked.
  • "permanent": true: Whether the objective is permanently scored once obtained. If false, this objective would be lost when the opponent drops their wheat_seeds.

Number Source ​

Some of these JSON properties describe a "Number Source", which can be one of three values:

  • Constant: "count": 8 - providing a direct number to use for the value
  • Options: "count": [8, 16, 32] - providing an array of options from which a number will be randomly chosen
  • Randomized: "count": { ... } - providing a min/max from which a random number will be generated
    • "type": "random"
    • "min": 8: The lower boundary for the item count (inclusive)
    • "max": 32: The upper boundary for the item count (inclusive)
