A PartType can be seen as a group that several parts fit in, e.g. items

Create a new PartType

If you, for whatever reason would ever need to register a new PartType, you will need to know two things:

  • What name the new partType will have
  • How MaterialParts created from Parts that are of this type will be registered

The first is simple, it's a string.
The second is a bit trickier, it's a function that takes a MaterialPart as input:

#loader contenttweaker

import mods.contenttweaker.MaterialSystem;

val ourType = MaterialSystem.createPartType("cool_type", function(materialPart){


//Use the new type to create a Part
val ourPart = mods.contenttweaker.MaterialSystem.getPartBuilder().setName("cool_part").setPartType(ourType).build();

//Create a new Material and register the newly created part.
val ourMaterial = MaterialSystem.getMaterialBuilder().setName("Lawrencium").setColor(15426660).build();
