1 Answer. When the front torch is off, the comparator extends the back signal, but if the side input is stronger (and not equal) the front signal will be off. When the front torch is on, the output will be the back input minus the side input, and will of course be off if the side input is equal or greater.
What are Redstone comparators used for?
A redstone comparator is a block used in redstone circuits to maintain, compare, or subtract signal strength, or to measure certain block states (primarily the fullness of containers).
What can comparators detect?
-Comparators can also detect the following: Detect if a container block (chest, furnace, hopper minecart, etc) has an item in it. Unstackable items give the signal strength of a full stack of stackable items. Items which stack to 16 output the signal strength of four 64-stack items for every 16 stack item.
How many torches does a Redstone comparator have?
Redstone comparators have three torches on them, allowing for complex redstone circuits to be built. Redstone comparators have three ports, with two being for input, the third for output. Redstone comparators also measure how many things an entity holds or weighs, allowing for some very interesting adventure maps or mechanisms.
How does the Magnum torch work in FTB?
From the FTB wiki: The Magnum Torch is a torch added by the Extra Utilities mod, which outputs the same amount of light as a vanilla Torch, but in addition it also prevents mobs from spawning in a sphere-like area with a horizontal radius of 128 and a vertical radius of 32 blocks. It will however not disable monster spawners within its radius.
How does Redstone comparator work in comparison mode?
Comparators in comparison mode. A redstone comparator in comparison mode (front torch down and unpowered) compares its rear input to its two side inputs. If either side input is greater than the rear input, the comparator output turns off.
What is the exact range of the Extra Utilities Magnum torch?
All the various wikis give the range of the Magnum Torch from Extra Utilities as “a radius of 32 blocks”. What shape is that? Circular, Rhomboid, or Square? In particular, if I make a grid of them, how far apart can they be? I’m playing Agrarian Skies version v3.1.4 (MC v1.6.4) if versions matter. Elliptical. From the FTB wiki:
