[1.7.2] Simple way to modify vanilla block properties

[LePheel]

I was just wondering if there was a simple way to modify the properties of vanilla blocks such as hardness or resistances.

I was trying to use code like

Block.obsidian.setHardness(25);

but it didn't seem to work on any of the blocks.

 

Does anyone know a simple method? I don't want to have to create custom blocks to replace each block that I'm trying to modify.

Perhaps I had placed it in the wrong spot in my code. I'll take a look at it again knowing that it should be working as intended. Thank you for the response!
