Modify the player UI?

I want to add additional screens and buttons the the users UI. is this possible?

 

Short answer: No.

Long answer: It's impossible (as of 1.4.1, no idea what Notch might do in the future) to alter to player's client without having the player install a client mod. Basically, the server cannot:

• Add new blocks or IDs
• Get player key presses (ie see when the player pressed the arrow keys)
• Change the client interface

However, IF you force every player to have a client modification, then you could, in theory, make a plugin that communicates with the client mod and adds buttons. This isn't exactly what your looking for, but http://forums.bukkit.org/threads/pr...-creatures-to-your-smp-server-soon-more.9140/ is similar to what you're thinking about.

 

Yeah i was just looking at that. it would be nice if there where a bridge like bukkit for the client side, where the users could just drop a mod into a mod folder after installing that initial mod. Closest thing i could find to that was TFC mod manager, a third party program (http://www.minecraftforum.net/viewtopic.php?f=25&t=141904) but the SMP is pretty cool.

Too bad there are so many restrictions on the server, you can make some pretty cool custom servers without having to bind things to existing items and UI elements. the possibilities would be endless. I am defiantly going to look into the SMP server mod there and give that a shot.
