Emerald Gate

The Emerald Gate is an item added by BuildCraft. It functions as an interface between all types of pipes and the Docking Station, respectively the docked Robot, via four configurable functions (see Usage). The gate has an AND and OR version plus a Clock Timer, Redstone Fader, Light Sensor and Autarchic design.

Recipe
The player can choose the desired mode (AND or OR) if they have placed all needed resources in the Assembly Table, and the chosen one is produced.

Usage
The Emerald Gate can be placed on all types and sides of the BuildCraft pipes with a right-click. By holding the crouch-key and right-clicking the gate can be removed without destroying the pipe.

Note: The basic function is that the gate checks the precondition in the right slots, and, if this precondition is true, executes the option in the left slots. The difference between the AND and the OR version is when it will trigger an action. If the AND version is used, and two or more conditions are set to trigger the same action, the action will only trigger when all preconditions are True. If the OR version is used and two or more preconditions are set to the same action, the action will trigger when at least 1 precondition is True.

Right-clicking on the Gate will open the GUI, which has four rows to configure functions. All slots can be reconfigured by clicking in the slot, or by dragging and dropping items. The possible options depends on the pipe where the gate was mounted:
 * All options like the standard Gate (see Gate)
 * Options from the Emerald Gates to interact with pipes and robots (see below)
 * Furthermore the Emerald Gate has the ability to interact with all types Pipe Wires to transmit and/or receive redstone signals over the BuildCraft wire system. An example with a Diamond AND Gate is shown in the picture. In the GUI the corresponding option can be selected if a pipe wire is connected to the gate (see section Additional options for pipe wire interaction)

Available options
The following options are available for the kinesis, fluid, and transport pipes:
