A part Data piece can be added to a PartType to be able to add some MaterialPartData to MaterialParts created with Parts that are of this PartType.

It might be required for you to import the package if you encounter any issues, so better be safe than sorry and add the import.
import mods.contenttweaker.PartDataPiece;

You can get a List of a Parts DataPieces using getData() on a Part.

Alternatively, you can register a new PartDataPiece using the MaterialSystem:

ZenScript
 Copy
mods.contenttweaker.MaterialSystem.createPartDataPiece(String name, boolean required)

Parameters:

• String name: The new PartDataPiece's name
• boolean required: Is the PartDataPiece required to be present on a MaterialParts in order to register it?

You can retrieve the following information from a PartType:

ZenMethod	Return Type
ZenMethod getName()	Return Type string
ZenMethod isRequired()	Return Type string
