So, as the title already suggests, I need some help figuring out, how I would approach to save who placed my specific block in the world. I already tried coming up with a Block with such properties, which is in the native game but couldn’t think of one.

I already tested around with some tile-entities but scrapped the code afterwards, because I couldn’t make it work.

The Mod is being implemented in Minecraft-Version 1.15.2.

 

I am glad for every piece of advice you guys can give me!

What did you do and why do you think it is not working?

Also you might find 

SkullTileEntity

helpful since it stores player's data in it as well.

You'd want a tile entity with a UUID field that saves to NBT. Then, override onBlockPlacedBy in your Block class, get the tile entity, cast it to your TE type after an instanceof check, and set the uuid field to the provided player's UUID.

I now got it working this way, thank you very much for the help!
