## About The Pull Request Assembly shells now use power from whatever machine/borg/mech/modsuit they are attached to the wires of, instead of their own power cell, when appropriate. As for the meat of this PR, circuit wirenet components function like NTnet and NFC components, but their signals are transmitted across whatever cable network the shell (or in the case of assembly shells, the machine or button it's inserted into) is connected to. These components are available with roundstart tech. ## Why It's Good For The Game Provides a somewhat intuitive way to make circuit networks that aren't dependent on external factors to continue functioning. NTnet components require a functional NTnet relay, which usually means they need telecomms to be working. NFC components have a range limit, and you need to provide a specific reference to the circuit being communicated with. Wirenet components, on the other hand, just need the shell to be anchored (or for assembly circuits, the thing whose wire it is attached to), and for the shell to have a cable under it. Also might indirectly provide a reason to use cable layers other than the default one. ## Changelog 🆑 add: Adds circuit wirenet components, allowing data to be transmitted and received over cable networks. qol: When attached to a machine, mech, modsuit, or borg, assembly circuit shells will use power from those instead of the circuit's own cell. /🆑
