Bukkit

mojang added support for custom spawner data, would you ever consider adding the ability for OP's to edit the spawner custom data.

for example you can now change the spawners spawn radius, spawn location, spawn rate and player detection distance
you can also make the spawners spawn any entity.

or is this feature not possible in bukkit?

SethBling (on YouTube) has made some MCEdit Filters for editing the spawners, but that is highly impractical if you run a server.

Also TMI now supports similar spawner editing, but that is only in single player

i found a plugin that does what i commented above, but it has not been updated, maybe you could add these features to your plugin:

here is another better one that i found, maybe u want to have a look at it

http://dev.bukkit.org/server-mods/ispawner/files/8-1-0-4-1/

ispawner's source is public. I see how he did some interesting things. I want to absorb some of these features.

In the near future, I will send ispawner's author a message asking for permission to use some components of his plugin.
