Yeah! You got Minecraft, and you're all ready to go! OR ARE YOU? Here is what your going to need to accomplish by sundown!
By nighttime, all the demons of the night rise from the ground and attack! You're going to need a temporary shelter. So get to punching those trees! Open your inventory by pressing E, and put that Wood in to get Wooden Planks. Use those planks to make a small shelter, and viola! Not the best house, but it will have to do. Craft a door (See #2: Crafting) and plop that in a available space. You're going to want some light, what little there is.
While your punching trees and getting those Wooden Planks, put those Planks in a Two-by-two formation in your mini-crafting area, and you've created a Crafting Table, the 1st important item your going to need in Minecraft! Take two planks and put them in a line formation, and you made four sticks! Well, what do you do with sticks? Why, you make a PICKAXE! A wooden one, to be exact. Plop a Crafting Table down, and Right-Click it. A bigger Crafting area is availible, and with that space, place the sticks in the middle and Bottom of the crafting Area, and fill the top row with Wooden Planks, and take that Pickaxe and start mining coal and stone! While mining, be sure not to venture too deep into the Cavern, or else you may get lost. Also, use the coal you collect to create torches! How do you do that? Go to a crafting area, and put sticks under coal, and take the torches! Now you can light up dark areas. This will be important in the first night. Next up, use the Stone to craft a Stone Pickaxe. To make a stone Pickaxe, do the same thing you did to make a Wooden Pickaxe, but replace the planks with Stone. Its getting dark, so you might want to hurry up home! While on your way home, kill some sheep to collect their wool. When at home, craft a bed by placing three wool over three wooden planks. It doesn't matter what color they are, just make one, and fall asleep until the morning, when all the monsters are burned by the hot rays of the sun.
To craft a door, simply place three wooden planks in each Column, leaving the right column empty.
Lets say its too late to make shelter, you lost your home, or any other crazy situation where you can't get home and your stuck in the endless waves of Zombies, Skeletons and Creepers! What do you do? Craft a SWORD! Depending on your situation, you can craft a Wooden/Stone Sword by placing 1 stick under 1 Wooden plank/Stone under another Wooden Plank/Stone. Use that Sword to fend off the Creatures of the night, and be sure not to die! When you die, you lose EVERYTHING! You can easily keep some stuff by crafting a Chest, by putting Wooden Planks in a Circle in your Crafting Table, leaving the Middle open. You can make it larger by simply crafting another Chest, and placing next to the original Chest. Be careful, Creepers don't burn in the sun, and they can easily sneak up on you in the morning and explode you, and your shelter!
Another thing you'll need is Food! Three animals that drop meat are Pigs, Cows, and Chickens. kill them, and take their meat. But wait! You weren't thinking of eating raw meat, were you? You're going to need to cook it. You'll need a Furnace. You make a Furnace the same way you make a Chest, but replace the Planks with Stone. Place it down, and put the Meat on the top square and some Coal on the bottom square. If you haven't gotten coal yet, Wood will do just fine for now. When your down, save it for when your really hungry, or eat it now, to regain your Hunger.
And just like that, your all prepared! Hope this helped!
