Versions
As of the 1st of June 2025, all future updates for ampz mods will require Voltaic API, and not Electrodynamics, in order to function. This update affects all the mods and brings world breaking changes, which are written in the changelogs. Note that this should however not corrupt your world. If you have such issues reach out on our discord channel!
MFFS intends to provide forcefield systems in Minecraft. Devices to protect your base from players, mobs, and even the friendly neighbor sheep!
This project is based upon Voltaic and requires this mod to run.

# Modular Forcefields (MFFS) 1.21.1-0.6.0
## New features
## Fixes
## New features
- Sponge module now works** — The sponge module no longer just sits there as a placeholder. It now actually removes fluids from blocks inside the field.
- Biometric identification for the field projector** — The field projector can now use a Biometric Identifier to let specific players pass through the field while blocking others.
- Rendered fortron rays** — The fortron beams/rays now render properly.
- Colourless fortron fluid texture** — Added a texture for colourless fortron fluid.
- Updated JEI and Neoforge** — The mod now uses newer versions of the JEI (Just Enough Items) and Neoforge libraries, keeping things compatible with the latest setup.
## Fixes
- Fixed Interdiction Matrix permissions, protection, and inventory transfers** — The Interdiction Matrix now handles permissions, protection, and moving items in/out correctly.
- Beams now use default Minecraft settings** — Added a config option so the fortron beams can be based on your default Minecraft settings.
- Reverted fortron field colour when modules are absent** — The field colour is now reverted when modules are missing.
- Removed deprecated code** — Old, deprecated code has been stripped out across the mod.
- Note: A large earlier commit ("Preliminary move to null-analysis-based system") introduced MFFS' null-analysis system and bumped the version to 0.6.0. It's the foundation for the changes above and doesn't need separate explanation for daily use.*
