Bedrock & Java Command Tutorial!

⚠️ Important Warning Before You Start

Before we dive in, there is one very important thing to keep in mind — you cannot undo this command. Please make sure you leave a backup of your world before attempting this. Once the TNT is placed, there is no going back, so it is always better to be safe!

What You’ll Need

The awesome thing about this command is that you do not need any command blocks at all. You can simply use the built-in command terminal in your game, making this incredibly accessible for everyone whether you are on Java or Bedrock Edition.

Step-by-Step: The Fill Command

First, go ahead and open your command terminal in-game. Once you have it open, we are going to be using the fill command. Start by typing /fill into the terminal.

After typing /fill, hit space and then autofill the first three coordinate values. These represent your relative position — meaning the fill will start from exactly where you are standing in the world. If you have specific coordinates you would like to use, you can manually enter those instead. For simplicity, autofilling your current position works perfectly.

Next, after your starting coordinates, add a space and then enter your ending coordinates — these are the X, Y, and Z values that define where the fill ends. For example, if you enter 10 for the X value, the command will fill 10 blocks in that direction. Adding 10 for the Y value means the blocks will fill 10 blocks upward from your position. Then add another 10 for the Z value to complete the three-dimensional cube.

You can go up to a maximum of 30 x 30 x 30 blocks, however this is not something I would recommend unless you are absolutely sure about what you are doing — it could potentially destroy a very large portion of your world! If you do want to go that big, just make sure your world is backed up beforehand.

Placing the TNT

Once you have your coordinates entered, the final step is to type TNT as the block type at the end of your command. Your full command should look something like this:

/fill ~0 ~0 ~0 ~10 ~10 ~10 tnt

Hit enter, and just like that — a massive cube of TNT will appear right behind you! It really is that simple. Keep in mind that you can use this same fill command with any block type in the game. I chose TNT for this tutorial because, well, what is better than blowing up the world?

Time to Blow It Up!

Of course, we could not end the tutorial without lighting it up — and the results are absolutely spectacular. Go ahead, grab your flint and steel, and enjoy the chaos (responsibly, on a backed-up world of course)!
