Feasibility of "Blackboard" Mod idea

[Sammdahamm]

Hey,

I'm new to the Minecraft modding community, so I'd just like to ask you guys a question.

 

Would it be possible to create a sort of "blackboard", which when used on a multiplayer server updates in realtime for all players to see. Sort of like how signs in Minecraft update once all the text has been inputted, except the text/drawing would be drawn to the surface in-game in real time.

 

Me and a friend are both second year computer science students with a fair amount of experience in Java, and we thought this would be pretty fun to do, but aren't sure if the Minecraft infrastructure would support this. We aren't interested if any existing mods out there already do this (except to confirm that it's possible), as we are just interested in working on a small recreational project.

 

Thanks in advance,

Sam

Awesome thank you Could you give any pointers in the right direction as to what I could research to accomplish this? I posted this question before I started looking into MC modding, just to make sure I didn't go on a wild goose chase.

I'm going to have a proper look now, but any pointers would be great thanks (y)

...and rather than sending the data when the typer hits "done" you send it immediately as soon as it changes.

Awesome that's enough to get me started, thanks guys!

Do you mean that people can draw freely on the blackboard, or type text on the blackboard? For text it would obviously just be a variation of a sign, except you could send each key as typed. If you want to draw freely, then I think you will need to do some graphics manipulation and send the texture over to others -- you'd have to look at regular Java methods for modifying the PNG.
