Script block 1
Power on: Set Power x,y,z
ClearBlock x,y,z (coord of what you want deleted)
Power off: SetPower x,y,z (on) (cords of Script block 2)
Script block 2
Power on: CleaBlock x,y,z (cords)
Power Off: SetPower x,y,z ( script block 1)
This definitely doesn't work.
Also you can test this as simple as using usng SetPower x,y,z (cords of the block of the script block OR a POWERED LIGHT)
The light will not turn on. without having a switch,button,wifi, pressure plate, look range.
so DO you HAVE to have 1 of those link to it if so the SetPower doesn't quite do much.....
