Make Explosive TNT Bow in Minecraft Bedrock MCPE Tutorial!

Hey everybody, it’s UnderMyCap, and welcome back to another video. Today I’m going to show you how to make an explosive bow.

I’ve already made a version of this for Java Edition. If you’re on Java, check the description for the link to that video—this method will not work on Java. This tutorial is for Bedrock Edition.

What You’ll Need

To set this up, you’ll need:

• 3 command blocks
• A comparator
• A repeater

Getting a Command Block

To get a command block, run:

/give @s command_block

Place the command blocks on the ground, and make sure the arrow on the first command block is facing the direction you want the chain to run.

Command Block 1: Detect the Arrow

The first command block checks for arrows, because we need to detect the arrow before we can make it explode.

In the first command block, enter:

testfor @e[type=arrow]

Set this command block to:

Repeat
Always Active

Comparator and Repeater Setup

Next, place a comparator coming out of the first command block. A comparator checks whether the command block output is true—so if an arrow exists in the world, it will power the next part.

Then place a repeater after the comparator, leading into the next command block.

Command Block 2: Summon the Explosive at the Arrow

The next command will summon an explosive at the arrow’s location. We do that by executing the summon command at the arrow entity.

In the next command block, use:

execute @e[type=arrow] ~ ~ ~ summon tnt ~ ~ ~

Set this command block to:

Impulse (or the appropriate type for your setup)
Needs Redstone (since it’s powered by the comparator/repeater)

Fix: Prevent Too Much TNT Spawning

If you test this by firing a bow, you might notice it spawns a lot of TNT. To prevent that, we need to change the TNT to a TNT minecart so it behaves properly for this setup.

Update the command to summon a TNT minecart instead:

execute @e[type=arrow] ~ ~ ~ summon tnt_minecart ~ ~ ~ minecraft:on_instant_prime

After switching to this command, testing it again should no longer spawn a huge number of TNT entities—now it will spawn the TNT minecart and trigger the explosion properly.
