Bukkit

What is the issue?
Basically I'm a bit of a noob at coding this but here's what I came up with:
My idea is to log every time an animal is killed, where it was killed and who killed it.
<event>
  <outcome affected_mobs="pig,cow,sheep,chicken,mooshroom">
      <actions>
        <log>Mob was killed by %player%</log>
      </actions>
  </outcome>
</event>

Also I'm looking to modify xp or item drops of mobs depending on whether they were killed in a certain coordinate (an incentive to use our arena for easier xp or different drops).
Many thanks for any help given :)

Both are possible. Place something like this in the dies.txt file:

<event>
  <outcome affected_mobs="pig,cow,sheep,chicken,mushroom_cow">
    <action_group>
      <actions>
        <log>Mob was killed by ^killer^</log>
        <continue/>
      </actions>
    </actions_group>
  </outcome>
  <outcome affected_mobs="pig,cow,sheep,chicken,mushroom_cow">
    <condition_group>
      <conditions>
        <x>above 10, 15 to 20</x>
      <conditions>
    </condition_group>
    <action_group>
      <actions>
        <drop_exp>50</drop_exp>
      </actions>
    </action_group>
  </outcome>
</event>

That's a quick example. Take a look at the tutorial website to see more actions and conditions.

Ok thank you :) With the first script it'll say who killed the mob, but will it also record the location of the event?

I can work the rest out though, getting the basic structure was something I wasn't sure about.

And I assume in the spawns file I could write similar code to the first one to log when withers are created (in the event someone uses it to grief a house).

All the event files use the same syntax so it would work (without the killer part of course).

Looking at the code, it seems I never added a location constant :( I'll add that soon. There is a ^world_name^ one though.

Ok been playing with the code but no matter how I do it (using tutorial) dropping items or exp doesn't work. Is this a known bug? P.s. thanks for all the help with the logging though, I'll make an individual event for each mob (so i know what mob was killed). Can't wait for location to be recorded also, will be a very useful anti-griefing tool :)

Lastly I'm wondering whether mobs has the ability to log spawning of a wither and who spawned it (location obviously once you update that). Is this possible? Thinking adding this and the ^killer^ tag (and any others) to the subelement page? You said they use the same syntax so would it be ^spawner^ to know who spawned a wither boss?

It's all in the works. I'm currently moving this all to a separate plugin which will handle all logging of actions and conditions (with different levels of information).
