[1.14.4] My Kingdom for a World

[Ommina]

Perhaps not a very good trade, but putting that aside.

 

Overriding Block's getWeakPower(), I have an IBlockReader instance (and a blockstate, blockpos, and side).  I need a World instance instead.

 

There are plenty of examples of getting a World instance in wilds of the Internet, but I've been unable to find anything current.  Searching for methods that return a World did yield IForgeDimension, but it didn't take me very far.

 

So -- where can I get my World?  If I missed something obviously, well, frankly I'll be quite pleased.

[Ommina]

Ah.  Not the response I was expecting.

 

I have a handful of functions that I'm calling from randomTick().  I would quite like to call the same functions from getWeakPower() without copying and pasting just to change the signature.

 

World also provides isBlockLoaded(), which I would like to take advantage of.

 

Three copy/pasted functions isn't the end of the world (teehee).  But I'd sure like to remove the duplication if I can.

(My) getWeakPower() checks the state of the four horizontal blocks surrounding it.  I can do that via IBlockReader, but I'd like to avoid loading any chunks to do so, if the block happens to be placed directly on the edge of an unloaded chunk.

 

And that's the only method from World that I need.

 

Everything else I can do with IBlockReader.  I just want to call the same functions from randomTick as I do from getWeakPower.  It's not so much a matter of missing a method (isBlockLoaded notwithstanding), but wanting to avoid a bunch of duplicated copy/pasted code.

 

If I do without the isBlockLoaded, I can cast randomTick's World to IBlockReader and get on with my life.

But World already is an IBlockReader, you don’t need to cast. 

[Ommina]

It is, indeed, an IWorldReader, which gives me everything I need.

 

Things look sharply less silly now.  Thanks so much.

 

[Ommina]

I've added the check, but it prompts a followup.

 

I was working under the assumption that if the IBlockReader was also an IWorldReader once, it would be each time.  Are cases such as "usually it is, but sometimes it might not be" typical?

What D7 means is that an IBlockReader is not necessarily also an IWorldReader. If the object you get is only one and not the other, just assume that neighboring blocks are loaded.
