Hey, a while ago I found a forum post you asked how to control Falling Block entities. Did you ever figure out how to do that? I am making a plugin and I would love some help if I could get it. I can't figure out how to get a falling block to stay in a "hover"
I see you have experience coding, we have a group of friends thats been working on a multi-gamemode server. We currently have one dev (me - but im still learning), if you are intrested go on thi slink and further instructions and infomation will be given. http://forums.bukkit.org/threads/bukkit-plugin-developer-wanted-the-core-multigamemode.160946/
