Hi guys, I got some problems with my mod.

Is the number of blocks breakable with a tool divided by 3 (from real number)) ?

And how the lastest breaking option work ? (times = {[2] = 1.10, [3] = 0.60})

And a last question, what's the maxLevel ? (maxLevel = 1)

Thank you for your answer.

the lines saying ''times = {[2] = 1.10, [3] = 0.60})'' are the lengths of time it takes to break a node of the group defined for that like (ex. ''cracky'' times = {[2] = 1.10, [3] = 0.60}) would mean it takes 1.10 seconds to break a node with the group ''cracky=2'' and 0.60 seconds to break a node with the group ''cracky=3'')
the part of the script saying ''uses = #'' defines EXACTLY how many times that tool can be used to break that type of node defined like the line saying ''cracky'' times = {[2] = 1.10, [3] = 0.60})
The MaxLevel has to do with damage, more of a level hurts more and less hurts less.
Example of a steel pickaxe:

This means it takes 4 seconds to break a node with a group as ''cracky=1'', 1.60 seconds for a node in the group ''cracky=2'', and 1.0 seconds for a node with the group ''cracky=3'', the tool can be used 30 times, and deals 2 damage per hit to an entity.

Ok thanks, your explanation is very instructive.
