|Redstone Fader Emerald Gates|
The Redstone Fader Emerald Gates are items added by BuildCraft and a specific design of the Emerald Gate, which functions as interface between all types of pipes and the Docking Station, respectively the docked Robot, via four configurable functions. The redstone fader design has a additional option available to interact with different strength of redstone signals (see Usage). The gate has also an AND and OR version.
The Redstone Fader 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 to destroy the pipe. Due to the special function of the Emerald Gates, this is placed next to a Docking Station (shown in the picture).
Note: The basic function is that the gate checks the precondition in the right slot, and, if this precondition is true, executes the option in the left slot. The bar between the left and right slot light up red when the precondition is currently True. The difference between the AND and the OR version is when it will trigger an action. Both will trigger if one precondition is true, but if the AND version is used, and two or more conditions are set to trigger the same action, the action will only trigger when both 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 either of the preconditions is True. The different to the Standard design is, that the Redstone Fader design has a additional precondition for all pipes to interact with different strenghts (1 to 15) of redstone signals.
With a right-click the player can open the GUI, which has four rows to configure functions. All slots can be configurated by clicking in the slot. The possible options depends on the pipe where the gate was mounted. Following options are available:
