What if I told you this block of dirt cannot be broken? Not in survival, not in creative. Yes, you heard that right. Meet the interaction entity, a hidden feature in the 1.19.4 update. Exclusive to Java Edition, of course. This is one of four entities added to snapshot 23W6A and 7A. Block displays, item displays, text displays, and again, the interaction. Interactions are invisible because they essentially operate as a hitbox. Map makers mainly use these to detect when a player clicks them. For example, this person used them to make a working piano in vanilla Minecraft, but these interactions are more overpowered than you think. If you place any block, stand above it than type this command. It'll summon a 1x1 interaction, preventing you from breaking the block inside. Even more, you can expand it to any size, and the only way to remove it is through slash kill. So forget about spawn protection, I'm putting these around my base.
