[TUTORIAL] Percentages and Chat Formatting

Percentages and Chat Formatting

Hello everyone! My name is GamerzKing, and I am creating this tutorial to explain how to fix the issue when percentages break the chat format, and why it happens. So, let's begin.

The reason the chat format breaks when a player uses a "%" in chat, is because Minecraft has special chat formatting already programmed in it. For example, if you type "%n <message>", it will put your message on another line, or if you type "%s", it puts your username is chat, etc.

So recently I have discovered a way to bypass this method, and not break the chat format. I tried to search for solutions on my own on the Bukkit forums, but came to nothing, so here is my solution/fix for this:

​

Code:

Player player = event.getPlayer();
String message = event.getMessage();

Firstly, I create my variables that I will use for my chat format.

Code:

message = message.replaceAll("%", "%%");

Secondly, and most importantly, I will replace the strings. This will replace all "%"'s with two "%"'s in the string "message".

Code:

event.setFormat(ChatColor.GRAY + player.getDisplayName() + " " + ChatColor.RESET + message);

I will then set my chat format, as usual. And of course, you can set your own colors and messages, these are just examples to help you with this tutorial.

Code:

        Player player = event.getPlayer();
        String message = event.getMessage();
      
        message = message.replaceAll("%", "%%");
      
        event.setFormat(ChatColor.GRAY + player.getDisplayName() + " " + ChatColor.RESET + message);

TL;DR

Hope I helped everyone looking for this solution! If you have any other questions regarding this thread, feel free to message me, or reply to this thread, and I will reply as soon as possible.
