Trigger readers effectively transmit redstone signal over a limited range by automatically watching and mimicking the redstone signal of any redstone signal creator block based off a given offset. This allows for less redstone wiring that would be needed for transmitting a signal over a long distance. An added benefit is that it is much safer to use then its transmitter counterpart: MC1110 which has unlimited range but can easily be tricked by someone using that same shortband name. It's main downside is that it requires correct offset calculations which takes some extra effort.

Note that over very long distances where blocks are not being loaded it won't work as intended. Both the reader and signal source need to be in loaded chunks. Also its important to remember that there is a tiny delay between the time it detects a redstone signal change and when it copies it so using normal redstone wiring might be needed if timing is important in close range.

Details

• Second line
  • [MCZ295]
• Third line
  • Specifies X, Y, and Z offset from the sign to a redstone signal creator block such as a lever or button.
    • The maximum X and Y offset is 999 but Y offset maximum is 255 because of the build limit.
  • Write down the coordinates of both the reader and for example a lever. Then subtract the lever coordinates from the sign coordinates.
    • Use this formula: (signX-leverX):(signY-leverY):(signZ-leverZ)

Performance Considerations

Automatic Trigger Reader MCZ295 operates by "polling". This means that it will use server resources while loaded even when not in use. Therefore if using more than a handful of these, perhaps consider using MC1110 instead.
