THIS TUTORIAL IS OUTDATED. The /replaceitem command was replaced (no pun intended) by the /item command in the 1.17 MC update. If you're NOT using the Java edition of Minecraft, or you're playing on a version under 1.17, this video will work. Otherwise, I have a video for you right here: • How to use the item command
This Minecraft tutorial will teach you how to use the /replaceitem command, a command allowing you to put something in a specific player's inventory, hotbar, ect
(Please note that my YT account has changed since the creation of this video)
