For simplicity's sake, I'll use the template: Plugin category: ? Suggested name: CommandBlockPermissions? What I want: I'm after a permissions-based system that allow non-operators to use command blocks, but only with certain commands. I want to allow my players to mess around with command blocks in only the creative world, so a plugin that simply allows usage without OP status won't do. Ideas for commands: None. Ideas for permissions: commandblock.tp, etc. for all the commands usable by the command block. When I'd like it by: Take your time.
http://dev.bukkit.org/server-mods/instances/ Does this. Default install should only allow editing in creative mode, though this is configurable in config.yml, with permissions per command as you asked. There's no per world permission / configuration though.
Awesome. It works like a charm, only I had to alias some commands so that they didn't interfere with my existing plugins.
