My last mod adds a block bookshelf that act as a container of books.

In the method isItemValid of my slots i made a check like this:

if (it instanceof ItemBook || it instanceof ItemWritableBook || it instanceof ItemEnchantedBook || it instanceof ItemWrittenBook)

 

Is there a way to detect if an item is a book so all books from other mods can be inserted?

 

Thx

Minecraft doesn't really have the concept of books, it just has several items that are called books and are indirectly related to each other.

 

The only way to achieve this is with a whitelist of book items and an API to add items to the whitelist.

Could be a good practice when creating new books to extend ItemBook? This would automatically solve the problem... 

I don't like to make string comparison with names of items as BiblioCraft because if i search for "book" in the name I will accept also bookshelf.

I prefer to make a list with Item.getByNameOrId(String id). And have i to send to client the server list when player connect? Correct?

Thx
