Bukkit

What steps will reproduce the problem?
1. Equip gold pickaxe
2. Right click to activate super breaker (see below)
3. Left click to mine using superbreaker

What is the expected output? What do you see instead?
Normally (without SunSteel) when using the super breaker ability of mcMMO degrades tools as if they were used normally, just much faster due to instant break. However when using this ability with a golden pickaxe, after installing SunSteel (so the molten pickaxe effect is active) the golden pickaxe does not degrade at all when using super breaker, but does degrade under normal use.

What version of the product are you using?
SunSteel 1.02h, git-Bukkit-1.2.5-R1.0-b2149jnks, mcMMO 1.3.05

Do you have an error log of what happened?
No

Please provide any additional information below.
mcMMO adds skills levels and abilities to skills. One of the abilities of the mining skill is super breaker. You right click to activate it, and then when left clicking, all ores, stone, etc. that you would use a pickaxe for, are mined instantly (with an increased chance of double drops). However, because you are breaking many more blocks than normal, the tool degrades very quickly. Unfortunately, when using SunSteel, the golden pickaxe is indestructable when using super breaker. I am also not sure if SunSteel also disables the double drop chance with the golden pickaxe (as in, does each block drop 1 iron ingot, or can it drop 2 iron ignots).

At this time I am providing no support for mcmmo compatibility as the way their plugin is written makes it very hard to do anything with. I may at a future time when I have more time on my hands adjust this but for now I will not. I will attempt a simple fix for this to see if it helps but I'm betting it doesn't. One of the major problems with mcmmo including the one you listed about double block drops is they have all their events set to monitor, which means no plugin can hook into the event after them. This is the cause for many authors that wouldn't mind adding plugin compatibility with mcmmo but not much we can do about it until they change it.

I posted this problem on the mcMMO issue tracker and this is what they said:

GJ added a comment - 04/May/12 8:14 AM We handle all our block drop events through custom events, and so as such there's no changes to the block break event and no reason to set the priority to anything BUT monitor. If you'd like, give me the author's contact info & I'll see if I can help him figure something out.

Would you want to work with them on this? I don't want to say sure go ahead if you don't want to.
