[1.7.10] Changing the maximum stack size for a block?

[Pokechu22]

I would like to change the maximum stack size for certain blocks.  Is it possible to do this?  I haven't found a way.

Not really. I'm pretty sure you'd have to make your own custom implementation of 'ItemStack' and your own custom Container/Inventory.

Use a custom ItemBlock. You can call methods in it like any other item.

A stack of "blocks" is really a ItemStack of ItemBlock.  Because ItemBlock extends Item you can use the setMaxStackSize() method.

 

So if you make your own custom ItemBlock you can change the stack size.  However, the maximum in the game seems to be 64. If you try to make it larger, then weird things will happen.  There are other threads on making stack larger than 64 and while it is probably possible it is a huge amount of work because you have to change all the inventories, the way inventories display, etc. to custom.
