Just wanted to share a neat little mechanism that can be used to simulate any logic gate. Here is the minimal set-up: S = incoming pulse X and Y = inputs A, B, and C = potential outputs Explanation: The incoming pulse activates the skeleton statue and instantly teleports the skeleton to the right teleporter and onto the hoik tooth. The hoik tooth propels the skeleton to the right, where it can take one of three paths, depending on whether one or both of the darkened blocks are in the actuated or deactuated state. If the middle block (a bottom hoik) is actuated then the skeleton will use the top hoik and be propelled upwards, passing over a pressure plate resulting in signal output A. If the bottom hoik is deactuated, but the block below it remains actuated then the skeleton is hoiked downwards, passing over a pressure plate that results in output C. Finally, if both blocks are deactuated then the skeleton is hoiked to the right, passing over a pressure plate that results in signal B. Summary: X=actuated Y=actuated output signal = A X=actuated Y=deactuated output signal = A X=deactuated Y=deactuated output signal = B X=deactuated Y=actuated output signal = C This universal gate can be used to simulate every possible logic gate although the starting actuated or deactuated state of the blocks might need to be set differently than what is depicted in the pic. All logic gates can be built so long as there are at least 3 potential outputs for the 4 possible input states, since any two potential outputs can be combined into one actual output by connecting the pressure plates with the same color wire. Furthermore, the skeleton statue can be replaced with a king or queen statue (and the lava needs to be removed) so that the player can be far away from any of the logic gates in the world and have them still function. The universal logic gate generates output signals in 3/60th of a second after an incoming pulse activates the statue (assuming the activation of the skeleton statue and teleportation is instantaneous), since jumping from one tooth to another tooth takes 1/60th of a second. Even though certain specific logic gates might be simpler to construct (the AND gate for instance can be trivially constructed with one hoik track), this "universal" gate is more flexible and can be adapted to suit various needs.
