Stay Flooded!
A mod that prevents air pockets from forming when submerged blocks are destroyed, perfect for an aquatic playthrough :-)
⬇ Download on Modrinth
A simple data-driven mod which prevents air pockets from forming when blocks are broken underwater, and allows users to register custom fluid flooding behaviour through datapacks.
When a block is broken adjacent to a fluid, if there is only either fluid sources or solid blocks on each side and downwards, then the block will turn into a fluid source instead of an air block.
For information on how to customise the mod with datapacks, refer to the wiki.
If you encounter any bugs, have a suggestion or need help with the datapack customisation, don't hesitate to raise an issue
