TrainCarts/Attachments

A customized minecart is being edited using the attachment editor

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 one larger attachment.

Two model attachments are animated, demonstrating the use of hierarchy

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.

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. 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.
