Minecraft cheats:
Seeds: Make a hoe and keep using it on the grass. You will get standard seeds and even beetroot seeds from time to time.
Nether Reactor Core: You make a plus sign using 5 cobblestone, and in the spaces next left you put blocks of gold. It should be a 3x3 square then. Then on top of the block in the middle of the square you put your nether reactor core. The on top of the nether reactor core you put cobblestone. Then you make the plus like you did on the bottom without the blocks of gold. Then you punch the nether reactor core. P.S. You should probably bring a sword.
Nether portal: You get 14 blocks of obsidian. You make a row of 4 at the bottom, then 4 up on both sides. Then 2 connecting the top. Then you hit the bottom with flint and steel.
End portal: You need to put 12 end portal blocks around to make a 3x3 space between them. Do not put any on the corners. Put ender eyes in the ender blocks. If it does not work the first time destroy a block and try it again.
P.S. If you can't follow these instructions, look them up on the Internet or YouTube.
