First, you find a tree and start punching the wood. Once you get the wood, open your inventory and craft wooden planks. With 4 of those planks, craft a crafting table. Exit your inventory, place the crafting table on the ground, and open up the crafting table menu by clicking on it. Then craft sticks with the planks and use the sticks and planks to make a sword, ax, and pickax. When you get your basic materials, you can start killing sheep and other mobs. You can get food but sheep can also drop wool. One sheep drops 1-3 pieces of wool. You also need three planks on the bottom and 3 pieces of wool in the middle. To craft the bed and all of the color needs to be the same. Sleeping is very important cause if you are in a hardcore world the mobs are more powerful so sleeping is very important. As soon as you get the bed, place it down, and click on it to sleep, and if there are mobs nearby, then you can't sleep so you kill the mobs.
