Minecraft (PC Edition) is a sandbox game created by Swedish game developer Mojang Studios. Players can explore, create, and adventure in a virtual world made of blocks. The game world is infinite, composed of various types of blocks, including land, mountains, forests, caves, rivers, and more. Players can gather and craft blocks to build various structures and buildings, from simple huts to massive cities, with almost no limits.
In the free version of Minecraft, players can gather resources such as wood, stone, and ores to craft tools and weapons. Players can also plant crops, raise animals, fish, and cook food to sustain their survival needs. At the same time, players need to face threats from various hostile mobs like zombies, skeletons, and creepers. The game offers several different modes to choose from. In **Creative Mode**, players have unlimited resources and can freely create and build. In **Survival Mode**, players need to manage their survival needs and fight hostile creatures. There are also Adventure Mode, Spectator Mode, and others for players to experience.
Besides single-player, players can also play Minecraft with others in **Multiplayer Mode**. They can build, cooperate, or compete in the same world, creating their own virtual community. The official version of Minecraft is a very free and open game where players can explore and create according to their interests and imagination. Its simple operation and rich content have made it one of the most popular games worldwide.

Minecraft Free PC Edition - [Expert Guide] Redstone Basics—Repeater and Piston Section

First is the **Redstone Repeater**. This magical small mechanism can boost the signal strength of our Redstone current. A Redstone signal input from the back of the arrow can activate it, and based on the current setting, it will output a signal in the direction of the arrow after a certain delay. The adjustable mini Redstone torches on the plate surface of an unactivated Redstone Repeater represent the current strength of its delayed signal release. Generally, the further apart they are, the longer the delay, and vice versa.

An activated Redstone Repeater. It is worth noting that the repeater **does not** provide a signal to the Redstone lines on its sides.

A Redstone Repeater that provides a delayed signal. At the moment of the screenshot, it has received the Redstone signal but has not yet provided a signal to the other side.

Diagram illustrating the Redstone Repeater providing signal strength: Generally, a Redstone signal attenuates once for every block it crosses.
It's especially worth mentioning that if another **activated** Redstone Repeater is placed adjacent to the side of a Redstone Repeater, the latter will enter a **locked state**, maintaining its current active/inactive status until the repeater on its side becomes inactive.

The locked repeater in the image did not turn to an activated state despite receiving a Redstone signal.

Similarly, the locked Redstone Repeater in the image did not terminate the signal provision even when the signal input ended.
Due to the above properties, Redstone Repeaters are sometimes intentionally used to create **infinite Redstone pulse generators**. By utilizing the delay characteristic of signal generation, we can easily create an infinite Redstone power source with a specific pulse interval.


An infinite pulse circuit created using the properties of the Redstone Repeater. It only requires quickly toggling a switch once to start the entire Redstone circuit.

Next, we need to introduce a common application block: the **Piston**. Pistons come in two types: the **Sticky Piston** and the **Normal Piston**. The difference between the two is that a Sticky Piston can pull back the block directly adjacent to its piston face when the piston arm retracts, while a Normal Piston will only push the adjacent block away and has no retraction function.
For specific Piston applications, you can refer to the [Expert Guide] Redstone Elevator section, but here we will only list applications not mentioned before:
The movement of a Piston arm will destroy flowers, mushrooms, or other Redstone circuit components attached to a block. Therefore, Pistons can be used to **harvest crops**, act as a **shutdown device** for Redstone mechanisms, or as a **trap activator**. Additionally, the movement of a Piston will also **push mobs** and **stop water flow**. Hence, the use of Pistons is very versatile.

A trap that uses Pistons to confine a mob.


Example of using Pistons to push items.


Example of using Pistons to interrupt a water source.


A test group regarding Piston movement of items. You can see that solid blocks that can store items are often **difficult to push**. However, blocks like iron bars and glass panes **can be pushed**, while items such as torches will be destroyed by the movement. Similarly, flowers, grass, or saplings will also be destroyed by Pistons. Redstone dust and Redstone torches attached to blocks will also be destroyed into item form when pushed by a Piston.
But it is important to note that **Rails** will not be destroyed by Pistons, while doors and ladders can be. Furthermore, hard-to-break blocks like **Obsidian** also cannot be pushed.
How to get to The End?
You need to use the **End Portal**. **Survival Mode Method:** You have to kill Endermen to get 12 Ender Pearls, then combine the Ender Pearls and Blaze Powder to craft the **Eye of Ender**. Then, right-click on a block with the Eye of Ender; it will fly towards the location of the Stronghold. Follow it, and where it falls, dig down (you might not find the Stronghold). You may dig into a Stronghold, which will contain a pre-built End Portal frame. Stand in the middle and insert the 12 Eyes of Ender you brought into the End Portal frames one by one. This will activate the portal. **Creative Mode Method:** Find the **End Portal Frame** under Decorative Blocks and the **Eye of Ender** under Miscellaneous. Arrange the End Portal frames like this, then insert the Eyes of Ender, and it will look like the image below, and then you can enter.
