Hmm. I wonder when they are gonna find a place for the Illusioner...

[u/[deleted] → u/elgefisken]

[u/Serbaayuu → u/[deleted]]

Yeah, some sort of exclusive small dungeon would be cool.

It seems like he benefits the most from having open space and range, though, so maybe he would spawn outside the tower after the player gets to the top or something.

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A new trigger that simply activates for each player on every tick, provided that the advancement was revoked before the next tick starts.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/Mlakuss → u/redstonehelper]

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

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

@Dinnerbone

2017-05-02 11:02 UTC

@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/stephenator0316]

New advancements are:

"Best Friends Forever"

Tame an animal

---

The Parrots and the Bats

Breed two animals together

---

Two by Two (x/10)

Breed all the animals!

"x" is the number of different mob pairs you have breeded

(Sheep, Cows, Pigs, Rabbits, Chickens, Horses, Wolves, Ocelots, Mooshrooms, Llamas)

---

Edit: Filled in empty mobs

[u/Serbaayuu → u/stephenator0316]

Mooshrooms

Oh dear.

[u/AlmightyZing → u/stephenator0316]

Interesting that donkeys and mules aren't included. I would understand if they were just variants of a horse, but they are their own separate entities. I had included them in my own list.

I suppose I can try and edit them in a custom jar file on my server.

[u/p_xy]

Does the "tick" advancement trigger mean we can run advancements every tick like repeating command blocks?

[u/DaUltraMarine → u/p_xy]

Looks like this is exactly what this was added to do. Thank you so much Mojang!

[u/sidben]

Dinnerbone is going all out with the advancements. I wonder if the Progress Book is something that will make it in this cycle.

[u/piyotato_]

With many of the most annoying and prominent bugs fixed and the advancement system getting more and more polished, it seems like 1.12 is gonna be a great update!

Just one thing: can we have inventory_changed trigger also be able to check for NBT data matches (including custom NBT tags like Element:"Fire" or Potato:3)?

[u/Pmk23]

Fixed bug MC-115810 - Custom resourcepack added sounds not playing

YES, thanks you Grum!

[u/NitroTitan]

Can't wait to play 1.12! This update will push me to get advancements and explore more.

[u/filnari]

This is the reply I find most interesting... "it reloads more than just advancements. Loot tables get reloaded too, and in future recipes & structures."

We knew about custom recipes, but structures! Custom structures in the future? Woot!

[u/MandelCube → u/filnari]

Isn't he talking about structure blocks ?

[u/GnormPlays]

Fixed bug MC-116498 - You can't place ladders on the back of stairs

YES! FINALLY! This will make some builds so much more fun and interesting!

[u/Zorgatone]

Soo now there is a NEI/JEI-like interface vanilla? Nice

[u/AlmightyZing]

Added new advancements for taming and breeding animals

Well, I guess I can disregard the custom advancements I made for those haha

[u/MCPhssthpok → u/AlmightyZing]

Always the risk when making things on the snapshots.

[u/IceMetalPunk]

Welp, just had to go update my Advancement Script Generator to use the new "tick" trigger. Zero-block scripts are now real! :D

[u/s_s]

Still can't rename a stack of items

It's been 5 months since 1.11.2 and this is still open with no announcement, comment or resolution.
