Mastering Minecraft Lesson 1.0A Transcript

Welcome back guys! This is The Redstone Scientist here with the first lesson of “Mastering Minecraft: A Complete Course in Command Blocks.” If you guys want to know more about this series, check out the introduction video that I will link to on-screen... now. I highly recommend seeing that video before you begin this series.

“Basic Understanding of Minecraft”
If you think you have a pretty good grasp of redstone, redstone components, and game ticks AND redstone ticks, then I recommend skipping this lesson. This is probably the only time in this series that you will hear me recommend skipping a lesson.
Vocabulary for Todayʼs Lesson:
Redstone Dust, Signal Strength, Redstone Blocks, Redstone Torches, Buttons, Levers, Repeaters, Game Ticks, Redstone Ticks, Comparators
**back to world**
As you probably already know, redstone is the virtual equivalent of real- world “wires” and “circuits.”
In todayʼs lesson, we will be reviewing some basic redstone components that will help us out when working with command blocks. Remember, this is not a series on redstone wiring! This is a series on command blocks!
But it is important to understand the fundamentals. Letʼs start out with the basic components of redstone.
This is a piece of redstone dust otherwise known as a piece of redstone or sometimes just known as redstone. This is the heart of all redstone work. The best way to describe it, is simply as a “wire.” As you can see, it connects on all four sides to link up. Redstone dust transmits signals immediately. There are many different properties of redstone that we wonʼt go into right now. But one important thing to mention is redstone power or more accurately signal strength. If we power a piece of redstone with a redstone block, this piece of redstone outputs a power of 15. This is the maximum power that redstone can have. If we extend the redstone along here, you can see that each piece of redstone outputs one power lower than the previous. Meaning, the next piece is 14, the next piece is 13, and so forth, all the way until 0. It
is important to note that the different power levels do not have different effects on redstone components or command blocks. This means that a lamp powered by a signal strength of 15 will not shine any brighter than a lamp powered by a signal strength of 1. Instead of thinking of this concept as “power,” think of it as “an indication of how many more blocks our redstone signal can last before it turns off.”
There are many different ways to power redstone. We already saw one, the redstone block. With some exceptions, most “power-giving” redstone components, output a power of 15, the maximum. The “power-giving” components include but are not limited to, Redstone Blocks, Redstone Torches, Buttons, Levers, and Repeaters.
Letʼs talk about repeaters for a moment. Repeaters do exactly what they say, they “repeat” a redstone signal. To put it more clearly, “they extend it.” When redstone is fed into a repeater, regardless of the power , the repeater will output a full signal strength, 15. This means that you can use repeaters to use redstone over longer distances. There is a feature that repeaters have called “locking.” But for the most part, we do not need to concern ourselves with “locking” in this series. Repeaters also cause a delay from
the time it receives a signal to the time it outputs a signal. There are 4 possible delay settings. 1 Redstone Tick, 2 redstone Ticks, 3 redstone Ticks, and 4 redstone Ticks. You can cycle through these by right-clicking. A Game Tick and a Redstone Tick are two different things. There seems to be a lot of confusion over the lengths of these among beginners. To be clear, a redstone tick is supposed to last for EXACTLY 1/10th of a second. A game tick is supposed to last for EXACTLY 1/20th of a second. Game ticks are the computational cycle that Minecraft runs on. For our purposes, we do not need to delve any deeper into game ticks.
The final and possibly most important redstone component we will review today, is the Comparator. This is the command blockʼs best friend. There are a lot of complicated intricacies of comparators that we wonʼt cover today but there are a few MAJOR things to know about comparators. First, a comparator is capable of outputting a redstone signal strength based on the block that it is connected two. Second, a comparator is capable of comparing two signal strengths; either by seeing which signal is greater or subtracting one from another. Third, a comparator can act like a repeater but without the signal strength extension. Meaning, if a comparator receives an input signal strength of 13, the output of the comparator will
also be 13. This allows you to carry a redstone current long distances without dampening or raising the power. Fourth, no matter what, a comparator will cause a delay of one redstone tick. And fifth and finally, a comparator can output a signal from a command block based on the commandʼs success.
******
So... letʼs review
Redstone dust can have a max power of 15. Power dictates how many blocks a signal will carry. Power can be received from things such as redstone blocks, buttons, and levers. Redstone repeaters can reset a line of redstoneʼs signal strength to 15, allowing you to travel longer distances. Repeaters will cause a delay of 1 to 4 redstone ticks. Game ticks and redstone ticks are two different things. A game tick is 1/20th of a second and a redstone tick is 1/10th of a second. Comparators can compare two signal strengths. They can also output the same signal strength that it receives, allowing you to carry a signal you want to save, to another location. And finally, comparators have the amazing ability to analyze all
sorts of blocks and output a signal based on what is found, the most important of these blocks is the command block.
