I think a miscommunication occurred with my offset suggestion, Specially, I intended that the offset would be more like the distance between the generator and the wall, kinda like this
= gen,
= wall,
= spacer










this is a 2-radius force field with an offset of 3. This way, I could make a containment field via 4 field generators and facing them inwards, offseting it by one, and setting up a field. The generators could instead be inside the field, and facing outwards, and via the offset, not be touching the field, or intersecting the plane either, so it can be protected by it's own field.
Also, can you only deduct power for force field blocks that are placed, such as if there is already a block of dirt or similar, it probably ought not to place a field there. (although if it reinforces the block, and in the case of a door or torch, makes it impassable/applies damage, I think it is fine.)
Edit: It appears to destroy leavers if they are in the space when the field turns on, but it does not effect doors. It also does not drop a leaver, which I think it should under those conditions. Also, are these actual blocks, or are they simulated blocks (not sure how to say that, is it like just a force field, not force field blocks? Because if so, It would block you moving through a doorway, and also be displayed over-top of the door display, I think. Also, would prevent casting *shadows* in it, assuming any method to destroy the forcefield exists.)
Edit2: Also, can a wrench rotate it just like a power block is? rotate it to face the direction, or dismount it if already facing said direction?
