you can create a glass box to put items you want to show off in. Easy enough? But not for me. I can't make plugins. So many views. So little replies. EDIT by Moderator: merged posts, please use the edit button instead of double posting.
I'm not sure this is possible with a plugin, it seems as if you want to create a new "Display Case" item, which is only possible with a client side mod.
Showcase isn't what im really looking for. Showcase shows the items you are selling. There was one mod I saw on minecraft forums it's called (coincidentally) Display Case. You can see the thread here http://www.minecraftforum.net/topic/326743-15-01display-casev03-new-variations/ so maybe with some editing it can be compatible with bukkit. Anyone up for it?
although it is possible to do(only for the glass looking one none of the special colored ones), and i could even have it done by the end of the day. I'm not sure why you can't just use showcase, you don't have to sell anything with showcase you can just show items on there.
But showcase is outdated and does not work. Also, it only works with half slabs and conflicts with other mods.
