Structures

A structure is a custom multi-block build that Structory can recognize in the world.

Structures are stored in:

plugins/Structory/structures/

Each .yml file can contain one or more structures. Each structure is a top-level YAML section.

Basic format

structure_key:
  name: "Display Name"
  check-block: CAULDRON
  orientation: false
  options:
    notify:
      message: "<yellow>Structure created!"
  layout:
    levels:
      level0:
        level: 0
        type: STANDARD
        checkers:
          types:
            C: CAULDRON
            X: BLACKSTONE_WALL
          main:
            - "X*X"
            - "*C*"
            - "X*X"

Main fields

Field	Type	Required	Description
name	Text	Yes	Display name of the structure.
check-block	Material or custom block key	Yes	Block that players activate with Shift + Right Click.
main-block	Vector	No	Offset used to move the logical main block. Default is 0 0 0.
center-offset	Vector	No	Moves the logical center used by some effects and options.
orientation	Boolean	No	If true, Structory checks orientation. If false, orientation is ignored.
options	Section	No	Behavior attached to the structure.
layout	Section	Yes	Shape of the structure.

Structure keys

Use simple keys:

elder_altar:

Recommended style:

• lowercase letters;
• numbers if needed;
• underscores instead of spaces;
• no special characters.

Good examples:

elder_altar
astral_forge
generator_1
magic_portal

Check block

The check-block is the block players interact with to create the structure.

check-block: CAULDRON

For CraftEngine blocks, use the custom block key when supported by your setup:

check-block: "default:palm_wood"

The clicked block must match the configured block.

Layout format

The layout is placed under:

layout:
  levels:

Do not put level0 directly under layout. Use layout.levels.level0.

Correct:

layout:
  levels:
    level0:
      level: 0

Incorrect:

layout:
  level0:
    level: 0

Levels

Each level represents a Y offset from the structure center.

Level value	Meaning
0	Same height as the center/check block.
1	One block above.
-1	One block below.

Example:

layout:
  levels:
    level0:
      level: 0
      type: STANDARD
      checkers:
        types:
          C: CAULDRON
        main:
          - "C"
    level-1:
      level: -1
      type: STANDARD
      checkers:
        types:
          O: OBSIDIAN
        main:
          - "O"

Checker legend

checkers.types defines what each character means.

checkers:
  types:
    C: CAULDRON
    X: BLACKSTONE_WALL
  main:
    - "X*X"
    - "*C*"
    - "X*X"

In this example:

Character	Meaning
C	Must be a cauldron.
X	Must be a blackstone wall.
*	Ignored position.

* is useful when that position should not be checked.

Advanced checker format

You can also define a character with a section.

checkers:
  types:
    L:
      type: craftengine
      key: "default:palm_log"
    W:
      type: craftengine
      key: "default:palm_wood"
    G: GRASS_BLOCK

Common checker types:

Type	Use
simple material	Vanilla Minecraft block, such as CAULDRON.
craftengine	CraftEngine custom block key.
none	Allows empty or ignored matching depending on setup.

Orientation

Set orientation to false for symmetric structures:

orientation: false

Set it to true when direction matters:

orientation: true

When orientation is enabled, players must build the structure in a valid rotation. Use it only when the structure needs a front/back direction.

Structure protection

After a structure is created, Structory tracks it as an instance. Protected structure blocks cannot usually be broken directly.

To destroy a structure, a player may need to break the main block twice within the confirmation time configured in config.yml.

Instance files

Created structures are saved in:

plugins/Structory/instances/

Do not edit instance files manually unless you have a backup and understand what you are changing.
