I've added an item with a pickaxe and a pickaxe sprite but idk how to begin implementing the pickaxe part. is there a pickaxe class or something I have to call ? also is the durability the same as the max damage? I want it to be 1.5* the durability of a diamond pickaxe so I set it to 2343 but I'm not sure if that's right.

Yes, durability == max damage.

There should be plenty of tutorials about this subject online ([lmgtfy]how to make a pickaxe forge 1.7.10[/lmgtfy])

 

as much as I like lmgtfy links  that isn't at all helpful. if you could link to a specific tutorial which is up to date that would be helpful but most all but one of the results on the first 3 pages are download links to mods and the one moding tutorial says to use a enumhelper that doesn't exist anymore.

1) Make a custom ToolMaterial using

EnumHelper.addToolMaterial(...)

(parameters should be self-explanatory).

2) Make you item class extend ItemPickaxe, passing in your own ToolMaterial.

3) Make sure you register your item as a normal item.

4) Done.

Have I derped somehow?

Did you install FML or Forge?

import net.minecraftforge.common.util.EnumHelper;

oh ty...eclipse normally gives import as a mouse over option under those circumstances...

Normally.  Sometime it fails though and I do something like this:

ClassThatWontImport l;

Which makes it painfully obvious to Eclipse what it is I want.
