About this Mod

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

No generative ai was used in the development of this mod! :-)

Frequently Asked Questions

Stay Flooded! server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Server lagging with Stay Flooded! – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Stay Flooded! consumes the most tick time.
