A question and three Ideas.
first the question, will tubes work through force fields? so if I have a BC pipe or RP2 Tube will the items I send down them be blocked by the field? I wouldn't think they would but you never know.
ok now the ideas. what about a way to bring back the feature of how a tube field could tunnel through other force fields, but instead have it as a force field network. basically have a "network" upgrade block. and generator with a network upgrade will turn on and off together, they can piggy back on power(do a bit of a power daisy chain), and only they can penetrate each other. so if you wanted to have two area generator linked together you could(so you can have a larger area or to give it a closer shape), and you could have one power core that would power both of them, and the "primary" one that is linked to the power is the only one that needs redstone and it would activate both of them, and then the shield wall that both of them would have wouldn't exist but the exterior walls would still be there. I don't know how hard that would be to code or implement but it would be nice if you have a big base or a weird shaped one that you want to protect.
the second idea is for a "full shield" upgrade (I couldn't think of a better name). basically it would be like from star trek how when the shields were on full power no one could transport in or out. so a shield with this upgrade would block people from teleporting in or out (but internal teleportation would work, also here I am talking about the IC2 teleporters not using server commands). IDK how hard that would be to code but still it would make sense.
the last idea is more of a trap shield. it would be like a area field but it would deploy next to the generator not around it. it would just be a fun way to mess with people or to defuse a nuclear trap (by neutralizing the issue). to prevent it from being OP and used for grieffing it might have to have a small range limit and a time limit (so you could trap someone but only for a short amount of time before the generator burns out and it has to be replaced or something).
Thanks love the mod. even though I usually play single player it's just really cool to have a force field.
