Minecraft – command to display the coordinates in chat

Using Redstone Torches I have come up with a modular design to lighting up the Redstone Lamps. Do note the default state is on and you may need to invert the signal.

Modular:

The redstone dust on the right needs to be interchanged with blocks when tiling.

Front View:

Side View:

Back View:

As you can see the redstone dust is raised up at each interval so they will not conflict with other lines.

You can't test exactly for /f map, but you can do similar with /triggers.

First, set up the trigger objective:

/scoreboard objectives add fmap trigger

Then, when people type:

/trigger fmap set 1

You can select them with @a[score_fmap_min=1], or tell them something like:

/tellraw @a[score_fmap_min=1] {"text":"message"}

As a side note, creating a faction plugin with command blocks is a very ambitious goal, may be worth starting off with something simpler and smaller.
