About this project
What does Air Gap Fix add?
This datapack simply makes the block connect when a sign, banner or other wall block is placed on it. This fixes the "air gap" that forms when normally placing these blocks, which always looks a bit odd, the blocks just floating there.
Blocks:
All fences, walls, glass panes, bars.
Attachables:
All signs, banners, player heads, end rod, lightning rods, item frames.
When removing an item frame it doesn't update the block, so it stays extended. I left that in because you can use that as a feature, if you want a fence extended somewhere for example.
Let me know if you have any issues with this datapack or if there's other air gaps I should fix!
