A very large aspect of minecraft is redstone. Infact, redstone is probably what keeps me playing minecraft today. Ever since the piston update of beta 1.7, redstone has taken minecraft to a whole new level, with the ability to manipulate the entire world around you with the flick of a switch. In this guide I'm going to quickly cover a few great redstone tips you probably did not know!
Take a look at the picture above. Looks out of place right? Well actually, it's a really cool tip that can save you a lot of time and space. When you feed a redstone signal directly into a solid block, and there is a repeater either on the side going into or coming out of the solid block, the signal will pass through the block! However, this will not work when using a block such as glass, stairs, a halfslab, or any other block that's not solid, or can be seen through. An example is in the picture below.
As you can see, the signal is not traveling through the stairs, because they're not considered a solid block. Air is also considered a non-solid block, which makes for a very easy switch. If you hook up a piston to the solid block that the power is flowing through, the piston can go back and forth to turn on and off the power source.
An inverter is what it sounds like; it reverses a signal. If you send a solid signal into a block, and the block has a redstone torch on the opposite side, the signal redstone torch will be off. See the picture below.
However, there is a common problem many people have is misalignment. Below is an example of the wrong way to make an inverter.
Many people do this when they're cramped for space. Thankfully, this can be fixed easily by placing a piece of redstone on top of the block.
Even though the signal isn't going into the side of the block, it's resting on the top. Therefore, it has the same effect as a normal circuit.
Thanks to minecraft 1.5, we now have redstone blocks. Similar to diamond, iron and gold blocks, this lets you place 9 redstone on a crafting table and turn it into 1 redstone block. Not only is this good for storage, but it's a power source. Redstone blocks and redstone torches have only 3 traits that aren't similar:
- A redstone block cannot be turned off, but a redstone torch can.
- A redstone block doesn't give off light, but a redstone torch does.
- A redstone block can be pushed by a piston, but a redstone torch can't.
The 3rd step is the most important. Thanks to the redstone block, you now have a power source that acts like a torch, but can be moved from place to place with pistons. See below:
And then turn the piston on:
If you try to do this with a redstone torch, this happens (see below), and the redstone torch breaks.
Using a redstone block instead of a redstone torch is the perfect way to toggle a device on and off, because you don't have to destroy a redstone torch to do it. You only have to pull a lever.
An XOR gate is very simple to build. To build it, just refer to the two pictures below:
The mechanincs are very simple. Both levers change the state of the piston. However, this device can be hooked up to anything that takes power (A note for the more advanced minecraft redstoners: this device is technically a T-Flip-Flop with multiple inputs). This redstone cirucit is not used nearly as much as it should be, because it's the ultimate alternative to 2 buttons and a t-flip-flop. It's silent, faster, and easier to make.
You read the title. It's the mistake all TNT redstoners make.
