I have added a new property to my block, that is used by TESR to display the model in correct orientation. That all works very well, but before I release I wanted to make sure that the previously placed blocks will display correctly.

And that is not the case. They are basically gone. I don't get any notification in MC about missing blocks or anything in the logs. When I try debugging I don't see any code being triggered to get the tile entities or trying to load the block with preexisting meta (which would be -1 as there were no properties previously).

The way it seems to me is that in the block registry it registers the new blockstates with the facing values, but doesn't have anything in there for the previous no property state and then just skips putting those blocks in the world.

 

I guess there's something simple that I am missing here, but can't figure that out. Is there a way to make this backwards compatible so that the blocks without any property set would get a default facing set?

blockstates json (I know that normal shouldn't be required here, was just trying it with it as well, just in case it would help)

Thanks a lot. That did the trick. I am still not sure why I haven't seen the meta 0 in the debug previously, but who cares now that it works :)

 

As for the code comments. The array in createBlockState is on me (copy paste from vanilla).

 

The others not so much as they are from the code I have inherited and still need to do more clean up. But thanks for pointing them out anyway. At least the pointless checks were not on my radar.
