ShieldGrid

ShieldGrid is a NeoForge mod that adds modular energy shield systems to Minecraft.

Instead of placing a single magic shield block, you build a connected shield network using different functional blocks. Your shield can protect bases, machines, ships, moving contraptions, Create builds, and physics-based vehicles from outside threats.

Modular Shield System

A working shield is built from multiple connected parts:

Shield Controller
The main block of the shield system. It opens the shield GUI and lets you manage energy, settings, trusted players, player/mob entry permissions, upgrades, shield color, and shape mode.

Shield Module
A required field component. The shield cannot activate without it.

Shield Stabilizer
Another required core component. A shield system needs both a Shield Module and a Shield Stabilizer before it can work.

Shield Generator
Produces shield energy by burning fuel such as coal, wood, blaze rods, or lava buckets.

Shield Battery
Stores extra energy for the shield network. It does not create energy by itself, but it helps the shield survive longer.

Shield Range Extender
Increases the maximum protected area when connected to the shield system.

Shield Radar
A counter-defense block that can temporarily disable nearby shields. It has a cooldown and its own upgrade options.

Shield Relay
Links separate ShieldGrid networks that are not physically connected. It transfers energy from one linked relay to another, with energy loss during transfer.

Directional Shield Controller
The main block for directional shield systems. It creates a one-sided shield wall with 500 energy, its own GUI, upgrades, color settings, and entry permissions. It blocks projectiles from passing both outside to inside and inside to outside, and it can be turned on or off with redstone.

Directional Shield Projector
Creates the directional shield wall. The shield forms in the direction the projector faces and only protects that side.

Protection

Shields use energy to block, bounce, or reduce incoming threats.

They can protect against:

Arrows
Tridents
Potions
Ender pearls
Ghast fireballs
Thrown objects
TNT and creeper explosions
Mobs and players
Cannon projectiles with Create Big Cannons compatibility

Every blocked hit consumes energy depending on the threat. If the shield avoids damage for a short time, it starts regenerating. If its energy reaches zero, the shield shuts down temporarily before recovering.

Upgrades

ShieldGrid includes an upgrade system for both shields and radars.

Upgrades are rolled and installed through the GUI, and each shield or radar keeps its own upgrades separately.

Shield upgrades can:

Increase shield range
Improve regeneration
Reduce incoming damage
Add emergency protection
Reduce radar interference

Radar upgrades can:

Increase radar range
Reduce cooldown
Extend disruption time
Block shield regeneration after disruption
Make low-energy shields stay disabled longer

Extra Features

ShieldGrid also includes:

Shield GUI controls
Trusted player system
Separate player and mob entry settings
Shield color customization
Damage log GUI
Visual impact effects
Shield sounds
Spyglass information overlay
Energy-based shield states
Redstone control
Shield Radar counterplay

Create Compatibility

ShieldGrid includes optional compatibility for Create Aeronautics / Sable, allowing shields to work on supported physics-based contraptions.

With Ship Shape mode, the shield can follow the shape of a ship instead of only using a simple box area.

ShieldGrid also supports Create Big Cannons, allowing cannon projectiles to properly interact with shields instead of simply passing through or disappearing.
