Requires IC2 and Immibis Core (which is on the same download page)

To get started with this, you will need a Forcefield Core:
(electrolyzer, MFE, 2 electrolyzed water cells, 2 advanced circuits, 2 advanced alloy, energy modulator)
The energy modulator is a crafting ingredient made like this:
Connect the core to a source of power. Note that 1 EU = 10 forcepower.
Now you need a projector. There are several types of projectors, and each of them create a differently shaped forcefield.
There is a cooldown time after activating or deactivating a projector in which it may not be activated or deactivated again, to prevent spam.
All of the types of projectors require a projector base, crafted like this:
You "program" it with a pattern by crafting it with reinforced stone.
The circular diamond thing is a diamond lens:
This is an area projector, which creates either a cube or a sphere centred on the projector.
This is a tube projector. It creates a tube-shaped forcefield, extending in one or both directions from the projector. You can use a wrench to change the direction the projector faces.
This is a plate projector (previously called a deflector). It creates a flat forcefield some distance in front of the projector. Use a wrench to change the direction the projector faces.
This is a line projector (previously called a directional projector).
By default it can only create a forcefield in a line in front of it, but you can place line projector extenders next to it to make it project a flat forcefield in that direction.
This is the recipe for an extender:
There's also the "reactor containment field projector" - see the Nuclear Reactors section.
Okay, so you've got a forcefield core and a projector of some sort. Now what?
First, you need to craft a blank card:
Then place the card in the forcefield core to code it with that core's frequency. You can remove it immediately.
Alternatively, simply right click the core with a blank card to encode it.
Place the coded card in the projector to link the projector to the core (either via the GUI or by right clicking).
You can then apply a redstone signal to the projector to activate it, if the core has enough power.
All upgrades can be placed diagonally adjacent to projectors - they don't need to have a face touching the projector.
This is a camouflage upgrade. By placing one next to a projector, you can make the forcefield from that projector look like another block.
Note: Only certain vanilla blocks are currently supported.
This is a block cutter upgrade. By placing one next to a projector, that projector will be able to break blocks if they're in the way of the forcefield.
Works on all projectors.
This is a dome upgrade. Makes an area or tube projector only create the upper half of its forcefield (a half-sphere, half-cube or half-tube).
Only works on area and tube projectors.
This is a range upgrade. Allows projectors to be placed further from their linked core. Only works on forcefield cores.
This is a storage upgrade. Allows forcefield cores to store more energy. Only works on forcefield cores.
This is an underwater upgrade. If used on a tube or area projector, water and lava blocks inside the projector will be destroyed when the projector is turned on.
Only works on tube and area projectors.
This is a zapper upgrade. Makes the forcefield turn red and hurt entities that touch it. It also breaks boats.
This is an inhibitor upgrade. It prevents fields from different cores which are activated after the one with the inhibitor from appearing inside the field it's attached to. Only works on area projectors.
This is a reactor containment field projector. Place it one block away from a reactor (so there is a one-block gap between the projector and the reactor; it is acceptable to have it touching a chamber), or directly next to a zero-chamber reactor.
When it gets a redstone signal, it will create a 3x3x3 or 5x5x5 forcefield around the reactor.
If you manage to get yourself stuck in the forcefield, you can get out by breaking this block.
In the GUI is an option called "reactorwatercool." If set to true, there will be water inside the forcefield when it is active, for an extra energy cost.
If the reactor exceeds 75% of its maximum heat, the projector should automatically activate and will destroy blocks in the way of the forcefield, as if you had a block cutter upgrade, to contain any explosion. This is known to work in 1.2.5, but untested with the reactor overhaul in 1.3.2.
This is a reactor connector.
Place it in the wall of a reactor field, touching the reactor or a chamber, to conduct redstone signals and electricity through the forcefield.
It is explosionproof.
This is an MFD. Right click any side of a force field projector to move the field in the direction of that side (For example, click the top to move it down). Shift-click to move in the opposite direction. You cannot move forcefields while they are on.
These are from the old mod DeFence.
Chain link fence:
Chain link fences are indestructible normally, but can be broken instantly with cutters.
Barbed wire fence: (shapeless)
Barbed wire fences act like webs and cacti - slowing the player down and hurting them.
Code doors are also from DeFence. Either of the following recipes will make one:
Use the GUI to set a 1 to 4 digit access code.
Anyone who knows the access code can open the door.
If you didn't place the door, you can't break it, unless it's open or you're in creative.
