[1.17] How do I make a placed block create a structure? in Modder Support Posted September 29, 2021 2 hours ago, ForgetFunsize said: You have two options. You could manually create the structure by placing blocks individually based on the location of the player-placed block (Yes using x, y, z coordinates). Or you could load the structure using an nbt structure file based on the location of the player-placed block. I suppose it mostly depends on how large and complex the structure is. If it is fairly complex or large, Id go with the second option. It's not large or complex at all, so the first option works for me. Could you show me how to code that? Or explain in detail?
