A customized minecart is being edited using the attachment editor

Two model attachments are animated, demonstrating the use of hierarchy

Introduction

The Attachment Editor is an in-game interactive Map Display with which individual carts of a train can be customized. This menu is used to configure the appearance and behavior of carts, with a tree layout showing the different attachments. Each attachment represents a part of the train, such as a moving entity or a seat designation. Attachments added as a child to other attachments are positioned relative to the parent. This allows many attachments to be moved and animated together as a whole.

Basic usage

Command

To start using the attachment editor, players need to give themselves the map item:

Give the player the attachment editor map item

Command:	/train attachments
Permission:	train.command.editor

Editing

To edit a single cart of a train, and make it visible in the editor, you need to select the cart first.

» Editing

Navigation

Each attachment is displayed on a different row, with an indent to the right every time it is added to a new parent. To navigate between attachments, use the Up/Down (W/S) steering controls. For each attachment selected, different menus can be accessed by pressing Left/Right (A/D) and Jump (spacebar) afterwards. Once inside a menu, the sneak button (shift) can be used to exit it again. This behavior is the same for all other menus. To move around while still viewing the editor, it can be placed into the off-hand (typically F).

To add new attachments, duplicate them, change the position in the tree hierarchy, or to delete them, use the General menu denoted by three horizontal lines.

Dropping items

An item is dropped from the inventory, configuring the attachment

Menus where an item is being configured can be set instantly by dropping an item from the player's inventory. With the menu open, simply open the inventory, pick the item to set, and click on the outside of the inventory to drop it. The drop will be cancelled and the item set in the menu.

Numbers

Number sliders are used to configure numeric values, such position coordinates. Pressing the Left/Right buttons once will increment/decrement a very small amount. Holding the buttons for a longer time causes the number to increment/decrement faster and faster the longer it is being held down.

By holding Spacebar a number field can be reset to its default, usually 0. By holding spacebar and then pressing left/right, a special action can be performed. Usually this means inverting the value (-5 -> 5) or changing an angle in 90 degree steps.

Text

Text is input using an anvil menu. After typing in the desired text, click on the emerald to proceed, or the barrier item to cancel the change.

Setting using commands

Set a numeric or text value for the currently selected menu

Command:	/train menu set [value]
Permission:	train.command.editor

Gotchas

• Make sure to use /train save name to save your train regularly! Only saved trains can be restored
• Make use of the train storage chest to move your train around or to recombine the carts
• Change spacing between carts, and where wheels are positioned, in the Physical menu
• When animating, make sure your animation frames have a delta-T greater than 0. Otherwise animation speed will not function.
• The new Display Entities cannot be clicked by default:
  • If you cannot click to edit a train, look at it and do /train edit to select it
  • To allow players to click on the cart to enter a seat, make sure to add a Hitbox attachment.
• You can save a sub-tree of attachments in the Model Store in the General menu, and create it in multiple places using the Model Attachment. There is also a clipboard and import/export function.

Menu

Appearance

The Appearance Menu contains a selector at the top where the attachment type is configured, with the remainder of the menu automatically filled with this type's configuration.

Sequencer	Automatically plays effects. Used to create ambient sound loops, such as engine noises, or to activate particle effects on a loop, such as a smoke stack.

Physical

The Physical Menu configures the length of the cart and where the rail-tracking wheels of the cart are positioned.

» Physical Menu

Position

The position menu configures the position and rotation of the attachment. Includes additional options for some types of attachments, such as scale and transform options for items.

» Position Menu

Animation

Attachments can be animated, making them move or rotate around. This is especially useful for funfair rides, or animated doors.

» Animation Menu

General

The general menu is used to add new attachments, delete them, move them around, name them or load/save them from the model store.

» General Menu

Effect Activation

Effect attachments such as the sound attachment must be activated. First, the attachment must be named in the general menu. It can then be activated in multiple ways:

• Using the effect sign
• Using the /train effect <name> command
• Using the sequencer attachment
