Minecraft Bedrock Edition offers a vast creative canvas, and sometimes that canvas requires… restructuring. Whether you’re tidying up a build, clearing land for a new project, or implementing complex game mechanics, knowing how to delete blocks with commands is an invaluable skill. This guide provides a deep dive into the command syntax and techniques necessary for precise and efficient block removal in Bedrock Edition.
Understanding the `/fill` Command: Your Block-Deleting Workhorse
The cornerstone of block deletion in Minecraft Bedrock Edition is the /fill command. This versatile command allows you to fill a specified volume with a chosen block. By filling an area with air, you effectively delete the existing blocks within that space.
Basic Syntax and Parameters
The general syntax for the /fill command is: /fill <x1> <y1> <z1> <x2> <y2> <z2> <TileName> [tileData] [replace|destroy|keep]
<x1> <y1> <z1>: These represent the coordinates of one corner of the rectangular prism you want to fill.<x2> <y2> <z2>: These represent the coordinates of the opposite corner of the rectangular prism.<TileName>: This is the name of the block you want to fill the area with. To delete blocks, you’ll typically useair.[tileData]: This is an optional data value for the block. Most blocks don’t require a specific data value when used with/fill air.-
[replace|destroy|keep]: This is another optional parameter that specifies how the filling operation should interact with existing blocks.replace(default): Replaces all blocks in the specified area with the new block.destroy: Destroys the existing blocks, causing them to drop as items.keep: Only fills air if the destination already contains theairblock. This will not delete any blocks.
Essential Considerations for Using `/fill`
Before you start blasting away at your landscape, keep these points in mind:
- Coordinate Systems: Minecraft uses a three-dimensional coordinate system (X, Y, Z). X represents east/west, Y represents vertical height, and Z represents north/south. Use the F3 debug screen (or the equivalent on your device) to find your current coordinates.
- Command Block Limitations: If you’re using command blocks, remember that there are limits to the number of blocks that can be affected by a single command. For larger areas, you might need to break the process into smaller chunks or utilize functions.
- Undo with Caution: While there isn’t a dedicated “undo” command, you can use
/fillagain to restore the area, but you’ll need to remember what was there originally. Consider taking screenshots or saving a copy of your world before making significant changes. - Safety First: Be mindful of the area you’re filling. Accidental deletion of important structures is a common mistake.
Practical Examples of Block Removal with `/fill`
Let’s walk through some real-world scenarios to illustrate how to effectively use /fill for block removal.
Deleting a Simple Cube of Blocks
Imagine you want to remove a small cube of dirt blocks located at coordinates X=10, Y=64, Z=20. The cube extends to X=15, Y=68, Z=25. The command would be:
/fill 10 64 20 15 68 25 air
This command will replace all dirt blocks (and any other blocks) within the defined cube with air.
Clearing a Large Area for Construction
If you’re preparing a large, flat area for building, you might need to clear a much larger space. For example, to clear an area from X=-50, Y=60, Z=-50 to X=50, Y=70, Z=50, the command would be:
/fill -50 60 -50 50 70 50 air
Be aware that executing this command might take some time, depending on your device’s processing power.
Using the `destroy` Parameter for Item Drops
Sometimes, you might want to collect the resources from the blocks you’re deleting. In this case, use the destroy parameter:
/fill 100 64 100 110 70 110 air destroy
This command will delete the blocks within the specified area, and any blocks that normally drop items when broken will do so. For example, deleting stone will drop cobblestone.
Targeting Specific Blocks for Removal
The /fill command can also be used to selectively remove specific types of blocks. This is achieved by using the replace argument.
The syntax for selectively replacing blocks is: /fill <x1> <y1> <z1> <x2> <y2> <z2> <TileName> replace <TileNameToReplace>
For example, let’s say you want to remove all stone blocks in a specific area, but leave other blocks untouched. The command might look like this:
/fill 20 60 20 30 70 30 air replace stone
This command will only replace stone blocks within the defined region with air, leaving dirt, wood, and other block types undisturbed.
Removing Blocks Below a Certain Level
Another common task is removing all blocks below a certain Y-level. This is useful for creating underground spaces or clearing out caves. To do this, you need to determine the lowest Y-level you want to affect. The syntax will be:
/fill <x1> 0 <z1> <x2> <y> <z2> air replace
Remember that 0 is the bedrock level.
For example, to clear all blocks below Y=30 in the area X=-20, Z=-20 to X=20, Z=20, use this command:
/fill -20 0 -20 20 30 20 air replace
Combining `/fill` with Selectors for Dynamic Block Removal
Selectors allow you to target entities (including players) within the command. While /fill doesn’t directly target entities, you can use the entity’s position to define the area to be filled.
For instance, if you wanted to clear a 5x5x5 area around a specific player (named “ExamplePlayer”), you could use a command like this (although this needs some external logic to set coordinates based on the player):
/execute as ExamplePlayer run fill ~-2 ~-2 ~-2 ~2 ~2 ~2 air
This command would execute the /fill command as the player “ExamplePlayer,” filling a cube with sides of 5 blocks centered on the player’s current position.
Advanced Techniques and Considerations
Moving beyond the basics, here are some advanced techniques and important considerations for more complex block removal scenarios.
Using Functions for Complex Operations
For repetitive or intricate block removal tasks, functions are an excellent solution. A function is a text file containing a series of commands that can be executed with a single command.
To create a function:
- Create a text file (e.g.,
clear_area.mcfunction) in thebehavior_pack/functionsfolder of your world. -
Write your commands in the file, one command per line. For example:
fill ~-10 ~ ~-10 ~10 ~10 ~10 air
fill ~-5 ~-5 ~-5 ~5 ~-1 air replace stone
3. In Minecraft, run the command/function clear_areato execute the commands in the function file.
Functions can significantly simplify complex block removal processes, especially when combined with other commands and techniques.
Handling Large Areas Efficiently
When dealing with extremely large areas, the /fill command can become slow and resource-intensive. Here are some strategies to improve efficiency:
- Divide and Conquer: Break the large area into smaller chunks and execute multiple
/fillcommands in sequence. This can help prevent the game from freezing or crashing. You can combine this with functions or command blocks to automate the process. - Optimize Block Updates: Filling large areas with air can cause significant block updates, which can slow down the game. Consider temporarily disabling random tick speed using the
/gamerule randomTickSpeed 0command before executing the/fillcommand, and then re-enable it afterward. - Consider Structure Blocks: For repeating structures, using structure blocks to save and then delete the structure might be more efficient than using
/filldirectly.
Dealing with Water and Lava
Removing water and lava with /fill air can sometimes be problematic, as the fluids can flow into the newly created empty space. There are a couple of approaches to address this:
-
Use
waterorlava: Replace the water or lava blocks with more water or lava. While it sounds strange, this can reset the flow logic, effectively “containing” the fluid within the defined area. Then, fill with air.fill <x1> <y1> <z1> <x2> <y2> <z2> water replace water
fill <x1> <y1> <z1> <x2> <y2> <z2> air replace water -
Solidify the Fluid: Use commands to temporarily turn the water or lava into a solid block (e.g., obsidian or stone), then remove the solid blocks. This is a more complex approach but can be useful in certain situations.
Troubleshooting Common Issues
Even with a solid understanding of the /fill command, you might encounter some common issues. Here’s how to troubleshoot them:
- “Failed to execute” Error: This often indicates a syntax error in your command. Double-check the coordinates, block names, and any optional parameters. Pay close attention to spaces and capitalization.
- Command Not Affecting the Entire Area: This could be due to the area being too large for a single command. Try breaking the area into smaller chunks. It could also be related to permission issues if the command is run from a command block. Ensure the command block is set to “Always Active” and “Unconditional”.
- Unintended Block Removal: Carefully review the coordinates to ensure you’re targeting the correct area. It’s a good practice to test the command on a small scale before applying it to a larger area.
- Lag or Game Freezing: This is usually caused by filling extremely large areas at once. Try breaking the task into smaller steps, as described earlier.
Leveraging the Power of Command Blocks
Command blocks significantly enhance the power of block removal, allowing you to automate complex processes and create dynamic effects.
Setting up Command Blocks
To use command blocks, you’ll first need to obtain one using the command /give @p command_block. Place the command block in the world and interact with it to open its interface.
Chain Command Blocks for Sequential Operations
Chain command blocks are particularly useful for executing a series of commands in a specific order. Set the first command block to “Always Active” and “Unconditional.” Then, place a chain command block directly behind it. The chain command block should be set to “Always Active” and “Conditional.” This will ensure that the second command block only executes if the first command block was successful. You can continue chaining command blocks in this manner to create complex sequences.
For example, you could use a chain of command blocks to:
- Detect the presence of a specific block in an area.
- If the block is present, remove it using
/fill. - Play a sound effect.
Using Redstone for Triggered Block Removal
You can use redstone circuitry to trigger block removal events. This allows you to create interactive mechanisms where blocks are removed based on player actions or other game events.
For example, you could create a pressure plate that, when stepped on, removes a wall of blocks, revealing a hidden passage.
Mastering block removal with commands in Minecraft Bedrock Edition opens up a world of possibilities for creative building, game design, and world manipulation. By understanding the principles and techniques outlined in this guide, you’ll be well-equipped to tackle any block removal challenge.
What is the basic command to remove blocks in Minecraft Bedrock Edition and how does it work?
The most basic command to remove blocks in Minecraft Bedrock Edition is the /fill command. This command replaces all blocks within a specified volume with a designated block. To effectively remove blocks, you use the /fill command and replace the targeted blocks with “air”. This essentially deletes them from the game world.
The command requires you to define the coordinates of the volume you want to affect. You need to specify the starting coordinate (x1, y1, z1) and the ending coordinate (x2, y2, z2) of the rectangular prism. After defining the volume, you then specify the block you want to fill the area with, which in this case, is “air”. The general syntax is: /fill x1 y1 z1 x2 y2 z2 air.
How do I find the coordinates needed for the /fill command in Minecraft Bedrock Edition?
Finding coordinates in Minecraft Bedrock Edition is crucial for accurately using the /fill command. There are a couple of straightforward methods to obtain these coordinates. The easiest way is to enable “Show Coordinates” in your game settings. Navigate to “Settings,” then “Game,” and scroll down until you find the “Show Coordinates” option. Toggle it on.
Once enabled, your current coordinates will be displayed in the top left corner of your screen. Simply stand at one corner of the area you want to fill, note the coordinates, and then move to the opposite corner and note those coordinates as well. These coordinates will be your (x1, y1, z1) and (x2, y2, z2) for the /fill command. You can also use the `/tp` command to get coordinates, but enabling the in-game setting is generally easier.
Can I remove specific types of blocks using the /fill command?
Yes, you can remove specific types of blocks using the /fill command along with the replace argument. This allows you to target only particular blocks within a defined area, leaving other blocks untouched. This is incredibly useful for selectively removing unwanted block types while preserving your desired build elements.
The syntax for this is: /fill x1 y1 z1 x2 y2 z2 air replace [block name]. For instance, if you only wanted to remove stone from a specific area, the command would be: /fill x1 y1 z1 x2 y2 z2 air replace stone. This will only replace stone blocks within the specified volume with air, leaving any other block types intact.
What are the limitations of the /fill command regarding the size of the area I can affect?
The /fill command in Minecraft Bedrock Edition has a limitation on the number of blocks it can affect at one time. This limitation is generally around 32,768 blocks. Exceeding this limit will result in the command failing to execute and an error message being displayed. This is implemented to prevent lag and potential game crashes.
Therefore, when using the /fill command, ensure that the volume defined by your coordinates does not exceed this block limit. If you need to remove a larger area, you may need to divide it into smaller sections and execute the command multiple times, targeting each smaller section individually. Careful planning of your coordinate boundaries is essential to staying within the limit.
How can I undo a /fill command if I accidentally remove the wrong blocks?
Unfortunately, Minecraft Bedrock Edition does not have a built-in “undo” function specifically for the /fill command. This means there is no single command that will revert the changes made by a previous /fill command. Therefore, taking precautions is very important to avoid mistakes.
The best way to recover from an accidental block removal is to manually replace the blocks. This can be time-consuming, so it’s always recommended to test the /fill command on a small area first, before applying it to a larger build. Alternatively, if you regularly back up your world, you can restore to a previous save before the mistake was made. Making regular backups is a good practice, especially before undertaking large building or editing projects.
Are there any alternative commands for removing blocks besides the /fill command?
While the /fill command is the most common and versatile method for removing blocks, other commands can also achieve similar results in specific situations. The /clone command can be used creatively to replace blocks with air. It involves cloning a section of air and then pasting it over the area you want to clear.
Another command that can be used, albeit in a very limited scope, is the /setblock command. This command replaces a single block at a specified coordinate with another block. While not suitable for removing large areas, it can be useful for precise, single-block removals by replacing the target block with air. However, for bulk removal, /fill remains the superior choice.
How can I use command blocks to automate block removal in Minecraft Bedrock Edition?
Command blocks offer a powerful way to automate block removal in Minecraft Bedrock Edition. By placing the /fill command inside a command block and triggering it with a redstone signal, you can create automated block removal systems. This is particularly useful for repetitive tasks or for creating dynamic structures that change over time.
To set this up, place a command block, enter the /fill command into it (including the appropriate coordinates and the “air” block), and then connect it to a redstone circuit. You can use various redstone components like buttons, levers, pressure plates, or even more complex redstone clocks to trigger the command block and activate the block removal process. Remember to set the command block’s mode appropriately (Impulse, Chain, or Repeat) depending on your desired automation behavior. The command block GUI will allow you to adjust these parameters as needed.
