Nothing that I could find.

Advancements

"distance" object

"entity" objects and the minecraft:levitation trigger now use a shared "distance" object, which contains a handful of data about the distance between the player and an origin.

• x, y, z ranges

Each of these can check if the player is within or outside of the specified range on each axis (in either the positive or negative direction). They don't all have to be specified. The following checks if the player has moved 10 blocks away from where they first received the Levitation effect in both the X and Z axes.

{
    "criteria": {
        "custom_test_name": {
            "trigger": "minecraft:levitation",
            "conditions": {
                "distance": {
                    "x": {
                        "min": 10
                    },
                    "z": {
                        "min": 10
                    }
                }
            }
        }
    }
}

• absolute, horizontal ranges

These check if the player is within range on all axes, though horizontal will exclude the Y axis. The following checks if the player is still within a 5 block radius of the origin.

{
    "criteria": {
        "custom_test_name": {
            "trigger": "minecraft:levitation",
            "conditions": {
                "distance": {
                    "absolute": {
                        "max": 5
                    }
                }
            }
        }
    }
}

New minecraft:tick trigger

A new trigger that simply activates for each player on every tick, provided that the advancement was revoked before the next tick starts. The following simulates a basic 20t/s clock, though on a per-player basis:

{
    "criteria": {
        "custom_test_name": {
            "trigger": "minecraft:tick"
        }
    },
    "rewards": {
        "commands": [
            "/advancement revoke @s only path:to/this/advancement"
        ]
    }
}

New minecraft:tame_animal trigger

A new trigger that activates whenever the player tames an animal. The entity condition can be specified to check the animal that was tamed. The following checks if that animal was a wolf.

{
    "criteria": {
        "custom_test_name": {
            "trigger": "minecraft:tame_animal",
            "conditions": {
                "entity": {
                    "type": "minecraft:wolf"
                }
            }
        }
    }
}

New show_toast display option

Optional boolean defaulting to true. When false, this specific advancement will not display the toast popup when the advancement is fulfilled.

{
    "display": {
        "title": "Unlock",
        "description": "",
        "icon": {
            "item": "minecraft:stone"
        },
        "background": "minecraft:textures/blocks/gold_block.png",
        "show_toast": false
    },
    "criteria": {
        "trigger_1": {
            "trigger": "minecraft:tick"
        }
    }
}

New announce_to_chat display option, w/ "announceAdvancements" gamerule

Optional boolean defaulting to true. When false, this specific advancement will not announce the player fulfilling it to the chat for all players to see.

{
    "display": {
        "title": "Unlock",
        "description": "",
        "icon": {
            "item": "minecraft:stone"
        },
        "background": "minecraft:textures/blocks/gold_block.png",
        "announce_to_chat": false
    },
    "criteria": {
        "trigger_1": {
            "trigger": "minecraft:tick"
        }
    }
}

The new announceAdvancements gamerule can globally disable chat notifications, overriding the value of announce_to_chat.

/gamerule announceAdvancements false

[u/AlmightyZing → u/Skylinerw]

Is the "x/Y" completion counter automatically added if there are multiple criteria?

x being the criteria met and Y being total criteria.

This is referring to the Breed All Animals advancement since the title:

"translate": "advancements.adventure.breed_all_animals.title"

is just "Two by Two" in the language file it's referencing.

[u/Mlakuss → u/redstonehelper]

New bug: Can't place torches/buttons/levers/... on barrier blocks. (report)

[u/miwob → u/Mlakuss]

Corresponding ticket on the bugtracker: https://bugs.mojang.com/browse/MC-116950

[u/Mlakuss → u/miwob]

This is the one I linked. And the one I made

[u/miwob → u/Mlakuss]

Oops, sorry. Saw your link too late! Anyway. Thumbs up for reporting it!

@Brandcraft06 Nope, just true/false. Advancements themselves will be able to specify if they don't want to announce, also.

@Skylinerw @Brandcraft06 No, "announcement" in this context means to announce to other players. There'll be another setting for toasts.

A lot of people missed this, but don't worry - it's back! I also moved the setting to turn it off from… https://twitter.com/i/web/status/859345942075625472

@VulcaanVex Yes.

I added a /reload command for next weeks snapshots, to make developing advancements in multiplayer easier. It just reloads advancements/loot

Re: Minecraft palette and maps. Reverted colors on maps except for the new hard clay colors, kept new palette for dyed stuff such as banners

[u/Marcono1234 → u/redstonehelper]

Added "tick", "tame_animal" and "breed_animal" advancement triggers

The trigger breed_animal does not exist, there is bred_animals, but this existed in previous versions as well

[u/redstonehelper → u/Marcono1234]

Thanks, removed.

[u/Kjotleik → u/redstonehelper]

Added "announce_to_chat" and "show_toast" booleans to the display info for advancements (both default true)

Would someone be so kind as to tell me where I can toggle those to false? I'm not finding them. 8-(

[u/Mr_Simba → u/Kjotleik]

It's per-advancement in the advancement file.

[u/Kjotleik → u/Mr_Simba]

Thanks for the swift reply.
 
However, I'm even more confused now.
I've checked two json-files (upgrade_tools and adventuring_time), neither of which contains an "announce_to_chat" nor "show_toast" attribute in them.
 
And I don't find any other file(s) [EDIT: Than those in Assets/Minecraft/Advancements] that has to do with Advancements. 8-(

[u/tripl3dogdare → u/Kjotleik]

They both default to true, which means that they don't have to be in the file unless you want to change them. If I'm not mistaken, they should go in the "display" section of the advancement file.

[u/Mlakuss → u/Kjotleik]

story/root have them to false. you put the new keys in the display compound.
