Fredashay's Welcome Book

Three time's the charm

Starting with Minecraft 1.16.4, the event PlayerJoinEvent is being fired twice each time a player joins the game, causing my plugin to give a new player two Welcome Books. I fixed this by checking if a brand new player already has a Welcome Book before giving him one :-/

Recompiled for 1.16

This plugin gives new players a welcome book. First create a text file in your Minecraft folder named: book(welcome).txt You can change the file title of the book from (welcome) to whatever else you prefer in the properties file, and also the welcome message. Edit this file with Notepad. Do not use a word processor like MS Word or Wordpad! The book file must be a pure text file. A book file looks like this: ^T Book Title ^A Author Name ^C Chapter Title ^P Paragraph ^P Another paragraph ^P Yet another paragraph ^C Another Chapter Title ^P Paragraph ^P Another paragraph ^P Yet another paragraph ^B A line break See my BOOK plugin for more information...
