Auto Command Speed Bridging Minecraft Machine! How To Build and All Commands!

Hey everybody, it’s UnderMyCap and welcome back to another video! Today I’m going to be showing you how to make your very own speed bridging training area. Have you ever been in that situation where you want to learn how to speed bridge and you have to create a world, get blocks, and then set yourself to survival? Well today I’m going to be showing you how to make an automated machine that cleans itself up every time you fail!

If you’d prefer to watch the video version of this tutorial, you can check it out here: Auto Command Speed Bridging Minecraft Machine! How To Build and All Commands!

What Does This Machine Do?

As I show in the video, when you speed bridge and purposely fall off, it displays a particle effect where you last failed and it also destroys all the blocks in your path. It also removes any blocks you may have placed on other layers as well, displaying a little particle effect to show that those blocks have been destroyed. This tutorial brings together a whole bunch of commands I’ve covered in previous videos, so if you’d like a refresher before diving in, I strongly recommend checking out my particle command videos, the play sound command videos, and execute videos as they will really help you understand how everything fits together.

Step 1: Setting Up Your Area

First things first, we want to make an area. I would strongly recommend choosing a unique block that you don’t often use in a normal world. For example, I don’t use a lot of red concrete, so we can use that to create the floor which will kill the player. To do this, open the command console and use the /fill command. Depending on the area you want to create, I recommend making it longer rather than wider, since when speed bridging you build outwards rather than sideways. I would set the blocks about 20 in front and 11 wide. The reason I use an odd number for the width is so that there is a middle area for the player to start on, which just looks a bit nicer. Make sure to also select the block type, so type in minecraft:red_concrete and press enter. You should now have your selected area.

If you’d like to add walls, I strongly recommend using the fill command again with a different block such as bricks. Simply use the same command, change the block type, and adjust the height to about 5 blocks. Repeat this for each wall until your arena looks the way you want it to.

Step 2: Getting Your Command Block

To get the command block, type /give @s command_block into the chat. Once you have it, place it in your arena and we can start building out the commands.

---

Step 3: Testing if the Player is on the Red Concrete

The first command we want to set up tests whether the player is standing on the red concrete block. To do this, type the following into your command block:

execute at @a if block ~ ~-1 ~ minecraft:red_concrete run kill @a

The three tildes represent the X, Y, and Z axes, and by setting the Y axis to negative one it targets the block directly beneath the player. Make sure you also have a redstone comparator attached, as this is what tests whether the command has been successfully executed. If you stand on the red concrete you’ll notice that you die, which is exactly what we want!

---

Step 4: Adding a Sound Effect

Now we want to add a little sound effect to make things feel more polished. Place another command block next to the first one and connect them with redstone. In the new command block, enter the following:

execute at @a run playsound minecraft:block.wooden_door.close ambient @a

I really like using the wooden door break sound because it makes it feel like all the blocks are breaking. Don’t forget to add your redstone comparator here as well, as that is what triggers the command. Now when you land on the red concrete you’ll hear the sound play in sync with the death effect, which ties everything together nicely.

---

Step 5: Removing Placed Blocks Automatically

This is one of the most important parts of the build. When you’re speed bridging, you want the blocks you placed to be removed automatically so you can start again quickly without having to clean up manually. To do this, place a command block next to your arena and use the fill command again to clear the area above the floor. The important thing here is to offset the origin point of the fill command slightly so that it doesn’t accidentally remove your command blocks, walls, or floor. Adjust your coordinates by one block across, one block forward, and one block up from the command block’s position. Set the height of the fill to about 5 blocks to cover the full area. Use air as the fill block and set the mode to destroy so that placed blocks drop as items. Connect this to your redstone chain and set it to repeat mode so that it continuously clears the area.

---

Step 6: Adding Particle Effects to Disappearing Items

Over time, dropped items from the destroyed blocks can accumulate and make the area look very messy. To clean these up in a satisfying way, we’re going to create a separate command row that removes any items sitting on the red concrete and adds a poof particle effect as they disappear. Create a new command block and enter the following:

execute at @e[type=item] if block ~ ~-1 ~ minecraft:red_concrete run particle minecraft:poof ~ ~ ~ 0.3 0.3 0.3 0 10

Then, give it a couple of ticks before using a kill command to remove the items:

kill @e[type=item]

Set this command block to always active. Now when blocks are destroyed, items will briefly show a poof particle effect before disappearing, which looks really satisfying and keeps your arena clean.

---

Step 7: Showing Where You Last Died

The final touch is adding a particle effect that shows exactly where you last fell off. Go back to your original command block that tests for the player on the red concrete and at the end of the command chain, add a run command with the flame particle like this:

execute at @a if block ~ ~-1 ~ minecraft:red_concrete run particle minecraft:flame ~ ~ ~ 0 10 0 0 100 force

The reason I’m adding this onto the existing command block rather than creating a new one is because this is the only block actively testing for the player on the red concrete. Having two separate blocks doing the same test can sometimes cause them to interfere with each other. The high particle count creates a very visible line in the air so you can clearly see where you fell off. Flame particles are one of the faster-fading ones, but if you’d prefer something that lasts a little longer, the end rod particle is a great alternative.

---

Bonus: Preventing Block Placement on the Floor

If you want to make it so that players cannot place blocks on the floor of your arena, this is really simple to set up. Copy the existing command block that handles block removal and adjust the fill coordinates so that only the floor layer is targeted, keeping the Y range at zero. With this active, any blocks placed on the floor will be immediately removed, which encourages players to stay in the air and keeps the speed bridging challenge fair.

Final Thoughts

And that’s basically how you make your very own automated speed bridging machine in Minecraft! It might not look as polished straight away, but you can absolutely add your own decorations, expand the arena, and make it your own. The one I showed off in the video has a lot more space and a few extra touches, and yours can too with a little creativity. I hope you found this tutorial helpful and that it makes your speed bridging practice sessions much more enjoyable!
