[1.8] extend Stair Block code

[Zenim]

Is there any kind souls out there that could show me how to extend the Stair Block class.

 

I have tried to follow minecraft modding stairs tutorial [1.8] Stairs by localtoast9001 but it will not work for me.

I have even looked at his complete source to try and work it out but due to the complexity of his mod I getting lost.

It's pretty awesome of him to put is hole mod source up there as its help me in other parts of my mod.

 

I don't need to now how to do the Json file and block state just how to get the class to extend and add the Material, HarvestToolEnum etc.

 

 

Edit

This is where i am up to

 

Code public class CustomStairs extends BlockStairs

 

I am not sure about "private static Block block;" but eclipse wanted to add it as " super(block.getStateFromMeta(0));" Block was alway in error.
