So, I'm trying to use findNearest (one that returns BlockPos of a structure) function in my create() method of my custom StructurePiece class and don't know the way I can get the instance of the World for that findNearest function

Can anyone help?

Hi

Where is your StructurePiece create() method called from?

For events and pretty much any other method you can attach your code to, there is nearly always an object available which has the relevant world in it.

This create() method is a part of a Piece extends TemplateStructurePiece class, which is called in my init() method through this.components.add method, maybe I should put a code here?

Here's my structure piece code:

public boolean create(IWorld worldIn

Uh...

Its not a World, but it still has all the info you should need.
