|Detector - Villager|
The Detector - Villager is a block from the Railcraft mod. This block is meant to output a Redstone signal based on the type of Minecart that passes in front of it. The Detector - Villager will output a Redstone signal if there is a Villager riding a Minecart and it matches the parameters in the Detector. They can be placed under or beside Minecart Tracks, and will output a signal to the side that has a small square. When a Redstone signal is active this square will turn red.
In the GUI of the Detector - Villager there are six buttons; two arrows, Any, None, Not, and Equals. If Any is selected, the Detector will emit a Redstone signal as long as there is a Villager in a Minecart in front of it. If None is selected, it will emit a Redstone signal when there is no Villager riding a Minecart in front of it. Use the arrow buttons to change the Villager shown in the center, this can be used to help define when a Redstone signal is emitted. If Equals is selected, it will only emit a Redstone signal when the Villager shown in the center is in the Minecart in front of it. When Not is selected, it will emit a Redstone signal whenever there is not the Villager shown in the center riding a Minecart in front of the Detector.
