When you are making your redstone suggestions, please note that Java and Bedrock will not have the exact same the same redstone systems - this would require redoing redstone system completely on one platform or the other. The two systems are functionally different and are going to stay that way. Please be sure to tag your suggestions with (Java) or (Bedrock).

Logic Gate

Add a redstone component called a Logic Gate. It has two inputs, one output, and an internal 4-entry table that specifies for each combination of inputs whether the output power level is 0 or 15 on the next redstone tick. Inputs for this purpose are identified as 0 (not powered) or 1 (powered). The table entries are programmable using a UI panel. The processing for this component is trivial and would not impose a burden on the redstone processing loop.

Obviously, this component serves as a programmable logic gate capable of implementing an arbitrary Boolean function on two inputs with a single block. For instance, it could be configured as an AND gate, OR gate, or XOR gate via programming, with no additional components necessary. This would enable existing circuits to be built smaller, faster, and more cheaply, or allow additional features to be added in the same amount of space.

One thing I haven't worked out for the Logic Gate is where its inputs are positioned. They could be on the sides for symmetry, or on one side and the back for topological convenience, but the latter would imply an asymmetry that's foreign to redstone. Maybe it should be the back and either side like a comparator, with the side inputs implicitly ORed internally.

    Good to see someone else had this idea. 

    Having to recreate basic circuit components with 4-12 blocks is not only tiring, but it makes fitting them into certain spaces practically impossible. 

    If redstone/minecraft had ACTUAL logic gate blocks, you could easily market this as an educational addition, because it would be exactly that. 

    Adding true Boolean Logic to singlular blocks would make building certain contraptions MUCH simpler.

    Or maybe even a transistor gate.

    I think this is a bad idea. I love being able to construct logic gates purely out of inversions (redstone torches). it helps me understand them better and i think the redstone computing community would dislike this because it takes away the challenge in creating "compact" circuts

    I really like this idea.  I really do.  I wonder what ingredients you would need.  I really hope to see this.

    I think the idea is good and usefully more like an end game or mid game item made from redstone dust, torches and other mid game items. The reason why I support is that it will make the redstone computers smaller and faster but open more possibility for redstone devices like subway system and other it will turn 3 or 4 tick adders to 1 tick I look forward for it. It sounds overpowered but will not be it could utilise the truth table logic. There also exist a mod for this but for Java only.

    I really liked your idea!

    My suggestion: logic gates NOT, AND, OR, NAND, NOR, XOR and XNOR could be different blocks rather than just one.

    As some have mentioned, separate components for Boolean functions would be more convenient to use, but I'd prefer a single programmable gate for several reasons: (1) It requires less development work (separate components would need individual textures and coding), (2) it's more flexible because it makes every Boolean function on 2 variables available, versus the standard AND, OR, XOR, NAND, NOR, XNOR, IMP, and EQV (if even that many were implemented), and (3) it teaches Boolean logic and how to use truth tables, important skills for the digital age that too few people are exposed to. And for those already familiar with them, programming any of the standard functions would hardly take 2 seconds.

    It's a great idea I have gates in my worlds but the truth is if they are big, an AND occupies 4x4x3 blocks that could be reduced to one or two would be great.

    I think this would be great! It would allow you to save space, especially if you were building non conventional gates. I thought of a recipe too:
    rtr r=redstone
    tct t=redstone torch
    rtr c=cobblestone

    This would save a lot of space and eliminate the need for the repetitive logic gate mods that are seen frequently!

    No, I disagree. The simple love of making huge computers and programmable contraptions (you heard me right) is the reason many people play this game. Adding such powerful block would remove the fun in many things that made minecraft so great in the first place. I believe additions should be made only if totally impossible before (block placers, etc).

    I see where your coming from. but every redstoner i know would HATE this feature. the complexity is part of the fun. it would also basically make redstone repeaters and stuff semi useless.

    Very bad idea. This limits creativity a lot.

    We already can make logic gates very easily. People have made computers in this game. The complexity is part of the fun, and I'm pretty sure most redstoners will agree with me.

    I've read many objections to the idea of logic gate blocks and they are all silly. Introducing logic blocks won't stop anyone from building logic gates the old fashioned way if they enjoy mindless, repetitive activities. And if you like "complexity" then you can just use the new logic blocks to build stuff that's even more complex than anything you built before.

    As an educational tool, forcing players to re-implement logic gates over and over and over again is pointless. In the real world, once you solve a computational problem, you encapsulate that logical problem in a module so you never have to deal with it again if you don't want to. You don't keep reinventing the wheel. Players would learn more by seeing how logic can be abstracted.

    On top of all of this, redstone behavior in Minecraft is just plain stupid and always has been. I'm not even sure that most of it was intentional to begin with as opposed to an unintentional byproduct of some sort of bug. You have to memorize nonsensical rules about how the various redstone components power neighboring blocks and how they behave when powered. In part this is because you can't place redstone dust vertically, so you have to invent implict rules for power to magically teleport up and down and through some blocks and not others. This all makes Minecraft logic gates and circuits way more complicated and confusing than actual, real world logic circuits that perform the same tasks.

    I guess I really don't understand the "complexity" issue, as I am not a redstoner myself.

    I prefer modded minecraft, and seeing this being a feature would remove the need for those hundreds of samey logic gate mods that basically do the same thing and get bunches of downloads.

    But people in the modded community don't really want to make the same gate with 30 blocks, 100 times because they just prefer convenience over challenge. Vanilla players probably prefer the challenge instead.

    So I can see why this would ruin the aspect of vanilla minecraft being challenging, especially for redstoners.

    I have a compromise suggestion about "complexity", if anyone who has played "Survivalcraft" will know that there is a hammer that reduces a building to a square. If the red stone structure can also be reduced to a square in this way and add ports on six sides, it ensures both complexity and modularity.

    Complicated redstone components that achieve something already possible have no place in Minecraft. If a tnt cannon or flying machine were a single block, it would take the fun out of building them, and people would no longer be inventing better designs. The infinite possibilities of redstone are a large part of the games re-playability for me, as i can always create new things that have never been done before. The idea of redstone is to let players use their imagination to build new things... not just craft a block that can do it for them.

    Redstone in Minecraft can also, believe it or not, give children the basic skills needed for a career in computer programming or other professions. They need to start with  creating something small, like a logic gate, not just be given complicated components and expected to make something only long-time players can create.

    wow me too! i would like this and an electric update for redstone for faster and more compact way of making redstone circuits you can search my post on electric update by the name "electric update" :)

    There's a mod that will give you this. I'm not sure how I feel about adding this to the game since i learned a lot constructing logic gates myself from simpler elements. As long as it's available as a mod, I think it's fine. But, mods come and go, projects get abandoned and it's not fun to have your world getting stuck at an old version because a mod isn't developed anymore.. Maybe would be nice if there was a set of "vanilla+" mods that were officially supported by Mojang?

    I have a compromise for this idea. It is called the circuit block. It is a block that has an input and an output. When you right-click it, it will teleport you to a 16 by 16 by 16 block mini-dimension. This dimension will have, on 1 side, the input, and on the other side, the output. You can build redstone contraptions that connect from the input and the output of the dimension. Once you are done and shift+right-click one of the block belonging to the dimension, you will be teleported out of the circuit block. Then you can power the block from the input and the block does whatever the contraption inside it does. This idea keeps a balance between the satisfaction of actually building your contraption and compactness. 

    Edit: This technically means you can create one block logic gates.

    I've seen a lot of arguments against this because you can already do it with redstone torches but you could have made the same argument for repeaters and they still got added to the game, this is a great idea for condensing large logic games down to a single block, however it would have to have a fairly simple interface like a daylight sensor or a redstone repeater where you just right click to change modes and that there is a clear indecator as to what mode it's in.

    logic gate is good idea, but better should be with more variations

    This would be absolutely insane, people could straight up make sophisticated computers so much smaller

    I think that having logic gates, despite dampering the fun of making the gates yourselves, would provide even more fun for more complex (and compact) systems. Imaging how much work you could cut out. the fun of making a redstone computer is arranging the logic gates, not building them, plus you can find tutorials online to help you build them, so there is no chalenge to making them except for pure tedium.

    A posible suggestion for those who still dislike the idea could be making a redstone circuit chest (like an integrated circuit). Opening the chest, you can map out circuits, such as logic gates, and have them connect to four sides of the chest. You could still build the circuits from scratch, or you can copy them (plus they can be even more than just logic gates.)

    I feel it could be a good creative only block. Especially when used with command blocks.

    NOT gates are torches, but this is still a pretty good idea. Maybe it could hard-power blocks.

    This should be in the game so players can build more complex machines in less space, there's no beifits to making a redstone repeater 1000s of times with redstone torches when you can have it in a single block and allow far more creativity because if it, logic blocks such as and/or gates would help Minecraft in the same way, it would allow players to be more creative than currently by making standard redstone logic smaller in size.

    PS: A t flip flop like block could be a good extension of this idea.

    My version of the idea was to create all standard logic gates (i.e. AND OR NOT XOR, etc.), as well as auxiliary ones (T-flip-flop, RS latch, 7-seg Redstone Lamp, etc.) and Redstone lamp variants with the corresponding emission color.  The primary ingredient (instead of stone) would be tuff (and only tuff), but the logic gates themselves resemble either smooth stone or iron
