How to add your own blocks to the game

NOTEBLOCK-type allows for up-to 1149 custom blocks. One per custom_variation

How to create a simple block?

Parent Models

The Nexo-item root configuration is the same as for any item (you can use any material like a diamond for example) and set an itemname, etc. It is recommended to not use a block for your material, sticking to such materials as PAPER For the pack section you can use your own model or texture for your block. If all you have is a texture, you can specify a parent_model and Nexo will generate the needed files for you. A Normal 1x1x1 block uses "block/cube_all"

my_block:
  itemname: "My block"
  material: DIAMOND
  Pack:
    parent_model: "block/cube_all"
    texture: my_block_texture.png

Each of these parent models take a different amount of textures. block/cube_all takes 1 texture, block/cube_column takes 2, block/cross takes 1, block/orientable takes 3 and block/orientable_vertical takes 2. For example, if you want to make a log block using the Directional Block mechanic, you should use block/cube_column.

All the vanilla models can be found at MCAsset. Find the one you want to use for your usecase. Recommend using a "texture map" in the config for multi-texture setups.

my_block:
  itemname: "My block"
  material: DIAMOND
  Pack:
    parent_model: "block/cube_top"
    textures:
      side: my_side_texture.png
      top: my_top_texture.png

CustomBlock Mechanic configuration

To use this mechanic you need to tell to Nexo which model to use (to use the generated one, just put the name id of your item). You then need to use custom_variation which is not already used by another block. Valid custom_variation is 1..1149

my_block:
  Mechanics:
    custom_block:
      type: NOTEBLOCK
      custom_variation: 2
      model: my_block
      drop:
        silktouch: false 
        minimal_type: STONE

Custom Sounds

Furniture, like custom blocks, can have custom sounds

myitem:
  Mechanics:
    custom_block:
      block_sounds:
        place_sound: block.stone.place
        break_sound: block.stone.break
        hit_sound: my.custom.hitsound     # Custom sound as defined in Nexo/sounds.yml
        step_sound: my.custom.stepsound   # Requires a sound-file in the Nexo/pack-folder aswell
        fall_sound: my.custom.fallsound

All the volume and pitch values are set to be what Minecraft uses for blocks normally. If you want to change the volume or pitch, you can do so by using the format below. Keep in mind these two formats are compatible with eachother. We recommend just use the default one, but the option is there if you want to change it.

myitem:
  Mechanics:
    custom_block:
      block_sounds:
        place:
          sound: block.stone.place
          volume: 1.0
          pitch: 0.2
        break_sound: block.stone.break
        hit_sound: my.custom.hitsound     # Custom sound as defined in Nexo/sounds.yml
        step_sound: my.custom.stepsound   # Requires a sound-file in the Nexo/pack-folder aswell
        fall_sound: my.custom.fallsound

Customize the breaking speed

You can customize the breaking speed and the most suitable tools with the hardness subsection. drop.best_tool dictates the "preferred tool" for this block which further tweaks the speed

my_block:
  Mechanics:
    custom_block:
      type: NOTEBLOCK
      custom_variation: 2
      model: my_block
      hardness: 20 # this makes it really hard to mine
      drop:
        silktouch: false 
        minimal_type: STONE
        best_tool: PICKAXE

Limited placing

You can customize what blocks a custom block/furniture can be placed on with limited_placing subsection. You can use the roof, floor and wall options to dictate where a block can be placed. By default, all are set to true. The type specifies if it should only be allowed on or denied on specific blocks. If type is ALLOW the block can only be placed on the given blocks. If the type is DENY can be placed on all blocks not matching the given blocks.

amethyst_ore:
  Mechanics:
    custom_block:
      type: NOTEBLOCK
      limited_placing:
        roof: true
        floor: true
        wall: true
        type: ALLOW
        block_types:
          - GRASS_BLOCK
          - DIRT
        block_tags:
          - base_stone_nether
        nexo_blocks:
          - chair
          - ruby_ore

The block_tags can be found at this page. Useful if you want to allow/deny a group of blocks. The block_types are materials. Useful if you want to allow/deny a specific list block. The nexo_blocks are blocks defined in the nexo configuration. This allows all custom blocks and furniture in here, but furniture requires a barrier-hitbox.

Beacon Base

You can also make a custom block work in beacons with the following:

my_block:
  Mechanics:
    custom_block:
      type: NOTEBLOCK
      beacon_base_block: true

A beacon will "activate" if any noteblock is in the pyramid, but the effect is only given when said noteblock(s) are base_beacon_blocks This is because it requires a Datapack that adds noteblocks to the given Tag, but it does not support individual blockstates

Blast-Resistant

You can make your custom-block blast-resistant by adding the following. If unspecified it defaults to false. You can also make your block drop something when it explodes by adding in_explosion: trueto your Loot like below

my_block:
  Mechanics:
    custom_block:
      type: NOTEBLOCK
      blast_resistant: true
      drop:
        loots:
          - nexo_item: my_block
            in_explosion: true

BlockLocker

You can use this to allow protection via BlockLocker Valid protectionTypes are CONTAINER, DOOR, ATTACHABLE

my_block:
  Mechanics:
    custom_block:
      type: NOTEBLOCK
      blocklocker:
        can_protect: true
        protection_type: CONTAINER

Storage

This is a sub-mechanic for furniture and noteblock mechanics, that let you make a custom storage container. Essentially a chest, closet or whatever you might want.

There's a few different types: STORAGE, PERSONAL, ENDERCHEST & DISPOSAL. STORAGE is similar to a normal chest. Anyone can open it and view the content of it. PERSONAL is essentially a custom enderchest, letting you edit the row-count and so on. ENDERCHEST is literally just the enderchest inventory, but letting you make a custom block/furniture to access it. DISPOSAL is a custom trashcan, letting you throw items in it, and they will be deleted when closed.\

my_block:
  Mechanics:
    custom_block:
      type: NOTEBLOCK
      storage:
        type: STORAGE
        rows: 5                             # Default: 6
        title: "<red>My Storage"            # Default: "Storage"
        open_sound: entity.shulker.open     # Default: entity.chest.open
        close_sound: entity.shulker.close   # Default: entity.chest.close

Falling Blocks

This is a sub-mechanic that mimics sand & gravel for your custom block. Placing it next to another block, with no block beneath, will make it fall

my_block:
  Mechanics:
    custom_block:
      type: NOTEBLOCK
      is_falling: true # Default to false if unspecified
