The MaterialSystem is used to create new or retrieve existing Materials from within CT.

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.MaterialSystem;

ZenScript
 Copy
createPartType(String name, IRegisterMaterialPart registerMaterialPart)

Required Parameters:

• String name: The part type's name → e.g. "dense_gear"
• IRegisterMaterialPart registerMaterialPart → A function that handles how the Material parts will be created.

ZenScript
 Copy
getPartType(String name);

Required Parameters:

• String name: The part type's name → e.g. "gear" For a list of all available part types check the part type page.

Unlike the PartType, you cannot directly create a Material, instead you need to use a MaterialBuilder. Check the MaterialBuilder entry for info on what exactly to do with these.

ZenScript
 Copy
val MB MaterialSystem.getMaterialBuilder();
MB.setName("Urubuntium");
MB.setColor(0);
MB.setHasEffect(false);
var builtMaterial = MB.build();

ZenScript
 Copy
getMaterial(String name);

Required Parameters:

• String name: The Material's name → e.g. "Platinum"

Unlike the PartType, you cannot directly create a Part, instead you need to use a PartBuilder. Check the Part entry for info on what exactly to do with these.

ZenScript
 Copy
val PB = MaterialSystem.getPartBuilder();

ZenScript
 Copy
getPart(String name);

Required Parameters:

• String name: The Part's name

 Copy
createPartDataPiece(String name, boolean required)

Required Parameters:

• String name: The Data Piece's name
• boolean required: Is the data piece required?

Even though you can also do this using the Material's own functionality, this Method allows you to register Parts for a given Material

ZenScript
 Copy
registerPartsForMaterial(Material material, String[] partNames);

Required Parameters:

• Material material: The material that the registered parts should be made of
• String[] partNames: The names of the parts that should be registered → e.g. ["gear", "ingot"]

You can use these methods to retrieve a map using strings as keys and the object as values:

Method Name	Возвращаемый тип
Method Name getMaterialParts()	Возвращаемый тип Map<String, IMaterialPart>
Method Name getMaterials()	Возвращаемый тип Map<String, IMaterial>
Method Name getParts()	Возвращаемый тип Map<String, IPart>
Method Name getPartType()	Возвращаемый тип Map<String, IPartType>

 Copy
import mods.contenttweaker.MaterialPart;

val part = MaterialSystem.getMaterialPart("name"); //as MaterialPart

val partMap = MaterialSystem.getMaterialPartsByRegex(".*"); //as MaterialPart[string]
