[1.6.4][SOLVED]How to make an Item effective only against a certain block

[The_Fireplace]

I would like to know how to make an Item break a block(obsidian us the one I'm going to make it break) with a much faster harvest speed than normal. I can't extend any classes to do it, my Item already extends something else. Any ideas?

Well if your Item extends Item (anywhere in its hierarchy), then in the Item class there's getStrVsBlock

 

Use that

This might seem stupid, but what do I make it return if I want it to mine Obsidian in 0.5 seconds(10 ticks)

I know it goes like

public float getStrVsBlock(ItemStack par1ItemStack, Block par2Block){
return ????;
}

The question marks are what I don't know. I think it's a number, like 2.0F

Might want to start with a number greater than 1.

 

If its too slow, make the number bigger.  If its too fast, make the number smaller.

 

(Note: bare-handed strength is approximately 0.25)

Ok, although I still don't know how to make it work against Obsidian.

if(par2Block == Blocks.obsidian) ?

 

Seriously dude, basic Java.
