Trapped Signs

This module allows sign upgrades that give signs the ability to emit a weak redstone signal, when right-clicked by a player.

Details

To trap a sign, throw a "trapped sign" item at the sign. The trapped sign item will disappear and the sign will become trapped. If a regular sign trap is used the last line of the sign will display "-x-". Otherwise the last line will be blank.

Right clicking a trapped sign will cause redstone dust within range to gain a signal strength of 1 for approximately one second.

Technical Summary

Any text placed on the last line of a sign will be deleted when the sign is trapped. A trapped sign only powers redstone dust, not repeaters or other redstone devices and only powers dust in certain spots around it.

A Wall Sign will power redstone dust directly adjacent to the block it is placed on. A Standing Sign will power redstone dust directly adjacent to the sign, or directly under the block the sign is placed on.
