I Want a custom block that when you interact with it, it displays a tellraw telling you who placed it and some other stuff. Is this possible?
#Can you track what player placed a block
oak furnace
fiery plume
@oak furnace I do not believe that information persists after the block is placed.
Only signs remember who placed them, if I remember correctly, although that data is not really accessible.
still zodiac
You might be able to do something with a custom entity, where they could spawn the entity and it would be owned by the person who spawned it. However I don't know how to make it tell who it's owner is so that probably doesn't help.
