[1.7.2] Providing power only for some specific metadata values

[JimiIT92]

Hi everybody! Here's is my question: i want to provide a power from a slab only if its metadata is 2 or 3. I have 8 half slabs wich have the same id but different metadata and i want that if this metadata value is 2 or 3 than the slab can provide power, else it can't...

I don't know how to do this beacuse in the "canProvidePower" method i don't know how to get the block metadata...

Here are the BlockOreSlab file and the (modded) BlockHalfSlab file

Actually it works but if i place another block that is "power-allowed" it gives power to blocks who is not allowed too

 

Here is a video to better explain what i'm saying

Why do people continually NOT deobf their code? It looks awful! Seriously, rename all your values to something more legible.

That's because they blindly copy-paste code. You can see that by this line: private static final String __OBFID = "CL_00000253"; as that's put in most vanilla class by forge when the code deobfuscated. If you don't remove those lines from your class, it will throw errors when building the mod.
