This is the first mod I've worked on in a few years now, last time I made a mod the current version of MC was 1.12.

I've been trying to get this send message to all players to work for about 2 days now, I've looked at sources for inspiration on why my message sends json instead of formatted text, to no avail.

As you can see in my source, the message to be sent is simple, "<player> went to sleep. Sweet dreams!", replacing <player> with their displayname.

The attached picture is how the text shows up in chat. I did try using TranslationTextComponent, but was not able to replace any of the text, so abandoned that idea quickly.

I'll probably be back here later to ask how to make sure this works both serverSide and singleplayer.

You cannot use toString on an ITextComponent, it will just give you a representation of its data (not JSON, by the way).

Instead of trying to replace in a string you should simply use text interpolation, which translation components support by defaut:

// in your language file:
"mymod.chatmessage": "%1$s went to bed. Sweet dreams!"

// in your code:
message = new TranslationTextComponent("mymod.chatmessage", player.getDisplayName());

 

Thank you for that.

Is it this part that is causing the representation, because I don't see any other spot where I use toString? "sleepingPlayer.getDisplayName().toString()"
