Redstone is the "wiring" in Minecraft used to connect one contraption to another, your power source within the game.
You can mine for redstone ore underground as with most materials in Minecraft. Redstone is used for powering various sorts of gadgets. Buttons send a redstone signal upon being pressed, while levers function more like light switches. Two kinds of pistons also exist in the Minecraft world: regular and sticky. Repeaters, as you might guess, repeat the redstone signal: one placed after the first fifteen blocks of redstone will extend your signal's reach for another fifteen blocks.
Redstone can even power up automatic farming and mining machines as well. Redstone can also enhance the brewing of potions.
Farming constitutes a valuable way to obtain supplies for your Minecraft adventures. Plant Farming
Once it becomes rows of dirt that look like farmland, take a seed you've found - either from destroying trees and other plants in survival mode or finding them in the materials tab in creative mode - then right-click where you want to plant your seed. To make your plants grow naturally, surround the field with a channel of water; an average time for full growth on water alone is 5-10 minutes. Right-click the plant to apply that bonemeal, and voilà! Depending on the size of the plant (e.g. grass vs. tree), it takes 1-5 clicks for instantaneous growth.
Once the plant is grown, it is ready for harvest. Destroy the plant to make the produce drop. Some plants that can be grown are sugarcane, wheat, pumpkins, and carrots. Mob Farming
Mob farming is more complicated than plant farming. The purpose of mob farming is not to grow plants but rather to "grow" a group of enemies that upon "birth" will die automatically, providing you with the items they will drop. One method that tends to work well is water + cliff. An essential component of mob farming is a completely dark enclosure, as any dark place within the world of Minecraft spawns enemy characters such as endermen and zombies, so keep that in mind as you start to explore the intricacies of mob farming.
Whether you prefer the more peaceful possibilities of farming plants, or the more adventurous world of spawning mobs for their dropped items, farming will be an important part of your Minecraft experience.
Mobs are a Minecraft term for all types of animated living things within the game: villagers, creepers, spiders, and so on. Creepers are the green and black alien-like character most commonly associated with Minecraft and they are both dangerous and annoying. Creepers hate cats. Tamed ocelots become cats which can be placed around your house at strategic intervals to ward off creepers. (Hint: feed ocelots some fish.)
Wolves typically travel in packs. If you hit one wolf, the entire pack will chase and attack you. The entire pack can be tamed with meat; right-click on a wolf with meat until you see hearts start to appear. As you would imagine, a tamed wolf becomes a dog and can be trained with bones and assist you with attacking enemies within the game. Two kinds of spiders inhabit the Minecraft world. Spiders poison you with damage over time and can climb your walls if you neglect to build an overhang. Kill a spider and be rewarded with string you can use for making a bow; spiders are easily killed by a gold or iron sword, as they are not very "healthy" creatures.
Zombies spawn at night and find the nearest village or person, swarming with the intent to kill. If you see a zombie horde heading towards a village, run the other way! Zombies can only break down wooden doors, so fortify your base with iron doors at the entrances. Zombies also burn when exposed to daylight.
If you want to altogether avoid the havoc wreaked by mobs, you can set your game to peaceful mode.
