Introduction

Force fields are your ship's first line of defense. They complement your ship hull with a different type of protection from direct hit and explosions. Complex force fields are build by networking multiple projectors through relays.

General principles

Force field relays can be used to network projectors together so you can merge and cover your whole ship. Force field blocks are linked as long as they share the same Beam frequency and stand less than 20 m away from each others.
Projectors don't propagate the network. Relays can be used without an upgrade.

Force field relays are also used to customized your protection with upgrades. Each relay can hold a single upgrade but it's effect will be shared to all projectors sharing the same network. Higher tiers relays will boost the upgrade effect.

Beam frequency

Each force field block has an adjustable beam frequency from 1 to 65000, included. Default beam frequency is 0, which is invalid.

Depending on its frequency, the force field color will change, along with its laser absorption rate. More importantly, when two Projector or Relay share the same frequency, they are considered part of the same network.

Beam frequency is set through tuning forks. To fine tune your beam frequency, you will need to attach a ComputerCraft or OpenComputers router and wire it to a computer.

Tiers

Relays exists in different tiers and can be used with projector independently of their relative tiers.

Higher tier relays have stronger effect from their mounted upgrade, applying this bonus to all connected projectors.

Usage

Simply right click a relay with an upgrade in hand to apply it. Shift-right click a relay to dismount its upgrade. You might need an empty hand for that.

Relays keep their upgrade and Beam frequency when broken.
