[1.12] Proper way to preserve BlockState Properties in dropped ItemBlock

[dakamojo]

Right now I have a generic ItemBlock registered for my Block.

 

event.getRegistry().register(new ItemBlock(Blocks.miner).setRegistryName(Blocks.miner.getRegistryName()));

 

My Block makes use of a PropertyInteger.  When my Block is broken I need the dropped item to preserve that value so that when it is placed again the new block will have the same value.  How do I do this?

 

Do I need to create my own ItemBlock?  Does anyone have an easy example of this that I can look at?

There are already two subclasses of ItemBlock, one of which should do what you need.

The issue is that the ItemBlock class (by default, unless override by a subclass) ignores metadata when placing its block.

In Forge or Minecraft?  What are they named?

[Draco18s]

Minecraft, they're used by wool, planks, etc. They're easy enough to find.

Right click -> open type hierarchy.

You'll want the one not called "colored" because it inverts the metadata value because Mojang made colors backwards.

Thanks.  Saw ItemColored but dismissed it because of the name "color". But after looking at the implementation it makes sense.  Thanks again.

Oh yeah, making a custom subclass is easy. You just have to override like, two methods.

It just so happens that for the most part, there's already ItemMultiTexture (iirc) that already does it.
