There is no command block in Minecraft.
If you go to the Minecraft WiKi it will have all the information you need for anything in the game.
Command block id: 138Type these in commands and replace with your username:/give 138(v1.7.9-) OR/give command_block
You need to be in creative mode in order to input commands into the command block.
Command block id: 138Type these in commands and replace with your username:/give 138(v1.7.9-) OR/give command_block
Command blocks are only obtained by creative or mods. You must be in creative mode in order to successfully type a command into the command block, otherwise you will be prompted to be in creative mode.
Command blocks currently can not be crafted. In creative mode the command /give YOURPLAYERNAME 137 1 will give you 1 command block (all you need in creative).
Command blocks can only be obtained using the give command and can only be successfully used by server operators in creative mode.The command block will perform certain commands when it receives a redstone current, these commands can be set by right-clicking on the block.
The id is 137 Type in ? /give (your name) 137Finish
16 bits per block . 8 16bit blocks = 128bits
Command blocks have the same properties as bedrock since 1.6. You can only break them in creative mode.
The only way to get a command block in Minecraft is to have cheats on in your world.Once you generated a world like that, type in the following command:/give [your Minecraft character's name] 137 [amount up to 64]That will give you a command block.
Nether Portals are constructed from Obsidian, so that's the block you would need. The Block ID for obsidian is 49 (command /give 49 1, remove if playing single player) and a Flint and Steel to activate the portal.If you mean the end portal, the block ID for End portal blocks is 120 and you'd need Eye(s) of Ender to activate this portal.
You are unable to craft command blocks in minecraft, but if you have cheats enabled on your singleplayer world, you may type /give {player} minecraft:command_block
