✔️ How to Use Minecraft Replace Item command! Detailed Step By Step Tutorial ✔️

Hey everybody, it’s UnderMyCap. Welcome back to another video. Today I’m going to show you how to use the /replaceitem command. This command is simple, really useful, and has a lot of fun applications. I’ll walk you through step by step, including how to use it on different entities (and on yourself) so you can do things like put a glass block on your head and look like an astronaut.

Replacing an Entity’s Equipped Item (Armor Stand Example)

Let’s start with my favorite example: placing a glass block on an entity’s head to create that astronaut-style “helmet” look.

First, use /replaceitem with the entity option, then target the entity you want. In this example, we’ll target armor stands:

You’ll start with:

/replaceitem entity ...

Then select a target. For example, you can use @a to target all players, or you can target a specific entity type using a selector argument. Since we’re doing this to an armor stand, we’ll use something like:

@e[type=armor_stand]

If you wanted to do it to yourself specifically, you could also just type your username instead.

Next, you choose the slot you want to replace. Since we want a “helmet,” we use the head slot:

slot.armor.head

Finally, choose the item. For this example, we’ll use glass:

minecraft:glass

When you run the command, the armor stand will immediately have a glass block on its head. It looks pretty cool.

Doing the Same Thing to a Player

If you want to put the glass block on a player’s head instead, you can target the player (or all players) the same way. For example, if you target @a, every player will get the item in their head slot.

After running it, you’ll see a glass block on your own head (or whoever you targeted), which gives that astronaut effect.

Replacing the Head Slot with Items (Not Just Blocks)

You don’t have to replace a slot with blocks only—you can also use regular items. For example, you can place a golden apple on an armor stand’s head.

Use the same structure as before, but change the item to a golden apple:

minecraft:golden_apple

When you run it, the armor stand will now have a golden apple on its head.

This can be useful for building tricks. For example, you can combine it with blocks (like carpet) to make the item look like it’s floating, which is a really cool visual effect for maps and decorations.

Important Note About Blocks in Other Armor Slots

One important thing to know: blocks generally won’t work properly in other armor slots (like feet, legs, or chest). For some reason, blocks work in the head slot, but they don’t behave correctly in the other armor slots. Items will still work in those slots, but blocks are basically an exception and are best used only for the head.

Replacing Items Inside Containers (Chest Example)

Next, you can use /replaceitem to replace items inside containers like chests, barrels, and shulker boxes.

For containers, you use the block option:

/replaceitem block ...

You’ll need the coordinates of the container you want to edit, and then you pick which container slot you want to replace. For example, the first slot is:

slot.container 0

Then choose the item to insert, like black concrete:

minecraft:black_concrete

Once you run the command while targeting a real chest (or other container) at those coordinates, the item will appear in that slot. If you run the command repeatedly, it will keep placing the item back into the chest.

This is great for things like refilling chests, infinite loot containers, or systems where you want a chest to always contain a specific item.
