So... I'm not sure I'm doing this the right way, as I have to look at someones else code as I'm not sure how written books work exactly.

 

But when trying this out almost everything works, with the detail that the content of the different pages isn't showing complete.

 

		ItemStack writtenBook = new ItemStack(Items.WRITTEN_BOOK,1,0);

	NBTTagList bookPages = new NBTTagList();

	bookPages.appendTag(new NBTTagString("Page one text"));
	bookPages.appendTag(new NBTTagString("Page two text"));

	writtenBook.setTagInfo("title", new NBTTagString("Test Book"));
	writtenBook.setTagInfo("author", new NBTTagString("American"));
	writtenBook.setTagInfo("pages", bookPages);

	EntityItem theItemEntity = new EntityItem(worldIn, playerIn.posX, playerIn.posY, playerIn.posZ, writtenBook);

	worldIn.spawnEntityInWorld(theItemEntity);

 

Each page shows "Page" as the text and not the complete line "Page one text" and "Page two text"

Each tag in the

"pages"

list must be the JSON representation of an

ITextComponent

. For a

TextComponentString

, you can simply wrap the contents in quotation marks (e.g.

new NBTTagString("\"Page one text\"")

).

 

If you want anything more complex than plain text, I suggest you create the

ITextComponent

for each page and then use

ITextComponent.Serializer#componentToJson

to serialise them.
