Detector - Item

The Detector - Item 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 - Item will output a redstone signal if there is a Chest Cart that contains the specified items in front of it. 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.

Usage
This detector has a GUI in which you can specify the required items in the Chest Cart to produce a redstone signal. By default this is set to Anything, which will output a redstone signal as long as there is a Chest Cart present. You can change it to Filtered, Not Empty, Analog, Empty, or Full. Filtered will show a second section, which is default set to At Least. You can change this to At Most or Exactly. Simply put the items you wish to require in the item slots, and change the second section to At Least, At Most, or Exactly, depending on what you wish to do. You can only put 9 stacks of ghost items in the slots. Not Empty will output a signal if the Chest Cart has anything inside of it. Analog will not output a redstone signal. Empty will output a signal only if there is absolutely nothing in the Chest Cart. Full will output a signal if the Chest Cart is completely full of items.
