Everybody, it’s UnderMyCap, and welcome back to another video. Today, I’m going to show you how to use the slash item command. This was formerly known as the replace item command, and I’ve done a video on this in the past, but that was for previous versions before 1.17. Please keep in mind that this video is only going to work on Java Edition. I do have a replace item Bedrock video coming out, so just remember that none of this will work for Bedrock; it will only work for Java Edition. With that said, let’s get straight into the tutorial. First of all, I’m going to type in slash and then “item.” Now, you’re presented with two options: modifier and replace. Replace will replace an item, similar to the replace item command, while item modifier will modify the item currently in your inventory. So, I’m going to use “item replace,” and then you have two additional features: these indicate what is going to be replaced. You can replace block items like chests or ender chests, or you can replace an entity inventory slot. For now, let’s do “entity,” and I’m going to choose myself. However, if you want to select everyone or just yourself—you can choose from all players, all entities, the nearest person, a random player, or yourself. Now, this is where it gets interesting. These are all the slots that you can fill or replace items in, which correspond to the main body components of the player. Let’s say I choose “head” and then type “with,” followed by “glass,” and hit enter. You’ll see that I get glass on my head. It actually looks quite cool, resembling an astronaut with a glass block. Now you might notice that in this command, some slots may not be available. For example, I can’t actually place glass on my feet, as that’s usually reserved for armor components, but everything else works. Now, moving from entity to another entity, if I did “item replace entity @e[type=under_my_cap] head with glass,” you’ll see that it attempts to replace whatever’s in that player’s slot with mine, though it doesn’t work right now. However, if I had two other players, it would replace whatever’s on UnderMyCap’s head with what I specify. Now, let’s say you want to replace an item in a chest or container. First, make sure that your character is looking at the item you want to replace. We’ll simply go “item replace,” and then type “block.” This time, you’ll notice that it starts auto-filling options because I’m looking at the block that I want to specify. Please note that you have to have your crosshair aimed at the block. Once you do this, it’ll show the same menu. This container refers to the chest slot. Chest slot 0 is technically slot 1, which you see when you open a chest. Slot 1 is actually the second one, and so on. So, for example, if I want to replace container slot 0 (which is technically slot 1) with, let’s say, eight boats, then if I hit enter, you’ll see that slot 1 has been replaced with boats. I’ll show you this is random, so it’s open. If I want to change, say, slot 17, you’ll see that it also replaced slot 17 with a boat. This command is also useful as you can replace items from entity inventories, such as zombies with their swords and similar items. Let me show you that now. If we go into the command and type “item replace entity @e[type=zombie],” we can change their head to glass. So technically, all the zombies in the world right now, if I have allowed them to spawn, will now have glass heads. They look like they’re wearing space helmets, which is really cool! The same goes for other mobs. I can do the same for creepers, but it appears that creepers don’t wear armor, so you can’t replace their armor slots since they don’t have any armor slots mapped. That’s all for now. If you enjoyed the video, please leave a like and subscribe. This video was really fun to create, and I’m glad to be back. I’ve been really busy with a whole bunch of schoolwork, so I’m pleased I could make this video. I’m also going to make a Bedrock version of this, so if you’re a Bedrock player, don’t worry—I have you covered! Thank you so much for watching, and I can’t wait to see you in the next video. See ya!
