Gates are placed on pipes to allow redstone signals to interact with Pipe Wire, and to detect whether or not items, power or liquid are flowing through the pipe. Autarchic gates can also replace Redstone Engines, allowing for much more compact pipe logic. All Gates are created with an Assembly Table, though it is possible to change an AND gate to an OR gate or vice versa by combining it with a Redstone Chipset in shapeless crafting. Some gates are among the items treated as Chips by GregTech.

Usage Edit

Right-clicking a pipe with a gate in your hand places the gate on the pipe. Like pipe wires, gates do not take up a block of their own, but appear as a modification of the pipe.

Shift-right-clicking the pipe with nothing in your hand breaks the gate, but not the pipe, while left-clicking the pipe breaks both. Breaking a gate in either way drops it as an item.

Right-clicking a pipe that has a gate on it brings up a UI for setting the behavior of the gate. Inputs will be on the left, outputs on the right. Clicking an input or output box cycles through the signals available for that box. Right-clicking cycles through in reverse order.(Note: If you are using the mod Morph, and are morphed as a different entity, you cannot open the UI for the gate)

The UI for Gold and Diamond gates also has a slot in each input/output pair for an item. This slot has a slash through it except when the input type is set to Items Traversing or Liquid Traversing, in which case it can be used to detect a specific item or liquid type.

Gate Quality Edit

The inputs and outputs available will depend on the type of gate. All gates can detect whether or not there is an item in the pipe and whether or not the pipe is receiving a redstone signal, and all gates can output a redstone signal. Iron and better gates can also detect and control Pipe Wire.

Gates also differ in the number of inputs and outputs they have. Plain gates have one input and one output, whereas iron gates have two inputs and two outputs. Iron gates and better, having multiple inputs and outputs, can be made as AND and OR gates, while plain redstone gates are a simple IF THEN structure.

If a gate's pipe is next to two different machines that can send a signal that the gate is listening for, the gate will perform an OR operation on those two inputs. This remains the case even for the more advanced gates that have AND variants. For example, a gate on a Wooden Waterproof Pipe pulling from a Still directly into an Iron Tank, if set to detect Tank Has Liquid, will activate if either the output side of the Still or the Iron Tank contains liquid.
