What is the new way of doing onBlockActivated in 1.11 (and up)

[Acrogenous]

@Override
    public boolean onBlockActivated(World world, BlockPos coords, IBlockState p_onBlockActivated_3_, EntityPlayer player, EnumHand handcontents, EnumFacing p_onBlockActivated_6_, float p_onBlockActivated_7_, float p_onBlockActivated_8_, float p_onBlockActivated_9_) {
        if(isIgnitable)
        {
            ItemStack fs = new ItemStack(Item.getItemById(259));

            if(player.getHeldItemMainhand() == fs)
            {
                System.out.println("it got this far");
                doExplode(coords,world);
            }
            System.out.println(player.getHeldItemMainhand());
            System.out.println(fs);

        }



        return super.onBlockActivated(world, coords, p_onBlockActivated_3_, player, handcontents, p_onBlockActivated_6_, p_onBlockActivated_7_, p_onBlockActivated_8_, p_onBlockActivated_9_);
    }

this does not work, when the block is right clicked with flint and steel (259) it should doExplode. the console does not display "it got this far" either

Do not use numeric IDs. They can and will change. Items class exists for a reason.

Comparason by reference like this will always fail since fs is a newly created object. You need to compare the content. Use ItemStack::getItem to compare Items and ItemStack::getMetadata to compare metadata.

I used number ID just in case that was breaking it, if you could please can you post an example of how I would go about using this?

 

I get "method references are not supported at language levels 1.6" if that helps

if (!player.getHeldItemMainhand().isEmpty() && player.getHeldItemMainhand().getItem() == Items.FLINT_AND_STEEL) 

Something like that.
