My First Block

Creating your first custom block

Resourcepack hosting

Remember to decide a resourcepack hosting method before you start. I advise you to use self-host which is easier and faster, but you can also use Dropbox and similar\

Configuration file

This is an example block (remember to change myitems namespace to the one you want).

For example I created a file which will contain all my custom blocks. I created it in the folder: contents/myitems/configs/

I start creating a simple block called red_block in the file blocks.yml.

ItemsAdder/contents/myitems/configs/blocks.yml

info:
  namespace: myitems
items:
  red_block:
    display_name: Red Block
    permission: red_block
    resource:
      material: PAPER

It's very important to use a non placeable vanilla material. For example PAPER. If you use a block (like STONE or DIRT) it will result a bit glitchy when placed.

Creating the textures files

To do that you have to put the .png textures file inside the correct folder.

In this case your namespace is myitems so you have to put them in this folder: contents/myitems/textures/block/

Alternative textures location

Alternatively you can put them in this folder too: contents/myitems/resourcepack/assets/myitems/textures/block/

Applying the textures files to your item

Now open blocks.yml file again and add the resource part as I did. As you can see I set generate: true and I set the textures for the item. This tells the plugin to generate the 3D model automatically using your texture.

info:
  namespace: myitems
items:
  red_block:
    display_name: Red Block
    permission: red_block
    resource:
      generate: true
      material: PAPER

Using different texture for each face

Important: keep the correct cardinal directions order as shown in the example.

info:
  namespace: myitems
items:
  red_block:
    display_name: Red Block
    permission: red_block
    resource:
      generate: true
      material: PAPER
      textures:
        - block/red_block_down.png
        - block/red_block_east.png
        - block/red_block_north.png
        - block/red_block_south.png
        - block/red_block_up.png
        - block/red_block_west.png

Using the same texture for each face

info:
  namespace: myitems
items:
  red_block:
    display_name: Red Block
    permission: red_block
    resource:
      generate: true
      material: PAPER
      texture: block/red_block.png

Adding the block placing functionality

You have to add the specific_properties attribute.

info:
  namespace: myitems
items:
  red_block:
    display_name: Red Block
    permission: red_block
    resource:
      generate: true
      material: PAPER
      texture: block/red_block.png
    specific_properties:
      block:
        placed_model:
          type: REAL_NOTE
          break_particles: ITEM

Getting the block ingame

Run /iaget red_block to get the item.
