How to configure different nodes to have hardness?

[Badkraft]

In MC, blocks have hardness which is what causes one block to be more difficult to break with an appropriate tool than others. An obsidian block takes significantly more hits to break with a diamond pick than a stone block. I want to introduce something similar.

I'm trying to figure out if it's possible as is or if I need to perform some function in a callback.

It is very possible to do this, read up on tool caps. At the time of posting this link takes you to that section in the API.

Read the info at the link. Looks like I might be able to do what I want which is to modify damage to the tool based on the node's hardness. Hardness is not a property of node, though.

I may be thinking too much on this aspect. I'll play around with the cracky value and such to see if I can tune the results.
