How to Get Command Blocks in Minecraft

On Java Edition

Start Minecraft. Double-click the Minecraft program icon to start Minecraft, then click Play on the launcher window if prompted.

Click Singleplayer. It's at the top of the Minecraft home page. You can also select Multiplayer here, though you will need to set up a multiplayer game through your own server before continuing.

Click Create New World. You'll find this option in the lower-right side of the window. If you already have a creative world with cheats enabled, click it, then click Play Selected World and skip ahead to the "Press /" step.

Enter a name for your world. Do so in the "World Name" field.

Click Game Mode Survival twice. It will change to Game Mode: Hardcore, and then Game Mode: Creative. Since you can only use Command Blocks in creative mode, this is essential. While it is possible to spawn command blocks in survival mode, you cannot place nor use the blocks in any capacity.

Click More World Options…. It's near the bottom of the window.

Click Allow Cheats OFF. This will switch this option to say Allow Cheats: ON, which means that cheats are enabled for your game. If this option says Allow Cheats: ON already, cheats are enabled for your world.

Click Create New World. It's in the bottom-left corner of the screen.

Press /. The "slash" key should be in your computer's keyboard; pressing it will bring up the command console at the bottom of the Minecraft screen.

Type give player command_block into the console. Make sure that you substitute your in-game name for "player" in the command. For example, if your in-game name is "potatoSkin", you would enter give potatoSkin command_block here.

Press ↵ Enter. Doing so will run the command and place a command block in your hand.

Place the command block on the ground. Right-click the ground with the command block equipped.

Right-click the command block. This will open the command block's window.

Enter a command. Type a command that you want the command block to execute into the text field at the top of the window.

Edit the command block's conditions. Click any of the following options to change the command block's conditions: Impulse - The block will execute its command once per right-click. Click Impulse to switch to Chain, which makes the block run after the block behind it runs. Click Chain to switch to Repeat, which forces the block to run its command 20 times per second. Unconditional - The block has no conditions for operation. Click Unconditional to switch to Conditional, which will keep the block from running until a block behind it has run. Needs Redstone - The block is fueled by redstone and cannot run its command without it. Click Needs Redstone to switch the block to Always Active if you want to bypass the need for redstone.

Click Done. Your command block is now set up. If the command block is set to require redstone, you will need to apply redstone dust to the block in order to make it work.
