BossMessage
#1
Hi guys!

I'm new at this community, so first i am gonna tell something about me.
I'm Corné, and i make custom plugins for Spigot and BungeeCord.
My lastest project is a perms plugin voor BungeeCord. But enough about Spigot and BungeeCord.
Lua is completly new for me, but i'm gonna try it.
BossMessage helps you to broadcast a message to all players.
I have here an example (I use this for my server) :
Screenshot

You can use it for: You are playing on {server} or for example a welcome message.
I hope it's ready next week, i first need to open my server at the 27th of July.
I will give you some updates,

Cya Cool

Welcome to the forum Smile
Unfortunately, you can't send this type of messages via lua (I think), because of the line below the text.

I think it will be possible with an API?!
I will try it out, if it's not possible i let you know Wink

I'm curious how bukkit does it. Do they spawn an ender dragon with a custom name at like Y-1000?

I don't know if *bukkit* does it that way, but I've played on servers that do that.

I'd guess that's the new Position param in the chat packet:

I don't think it's that because it works in 1.7 and maybe even lower MC versions. The position param might be for the new "Titles" (/title command). I'm not sure though because I remember seeing a new Title packet.
