I don't know whether this has been suggested yet,so i thought i will give it a try.
Name-Wifi blocker wall
Section-Walls
Colour-Very very very faint grey, almost invisible.
Properties:
~ Elements can be drawn in the wall without getting deleted (like DETECTOR wall)
~~MAIN PROPERTY: wifi cannot transmit spark out of this wall. so if there are 3 wifi with the same channel and if 2 of them are in this wall, the wifis in the wall can transmit spark to each other but not to the one outside. Likewise the wifi outside cannot transmit spark to the wifi inside.
~The wifi has to be covered by the wall, not inside the circle of the wall.
~Electrodes inside the wall cannot create plasma arcs with electrodes outside the wall.the same happens the other way around.
~Portals cannot transfer materials from inside the wall to outside,and vise versa.
Uses:
~For multiple electronics to function in a single save without changing all the wifi channels.
~Wifi spark control
~For testing electronic stuff
~Spark mazes
~Electronic art
~Electrode control
~For multiple portal pieces to function in a single save without changing all the channels.
