How to make lantern block?

Create a 3D Block (with Block Bench for exemple). After, import it in MCreator and put his luminosity to 15 (or something like this).

You want a block to change state based on which face you place it? Bottom face, side-face/top face?

It would be possible using procedures if you'd manage to store both the coordinates of what block the player is looking at and comparing it to the coordinates of where the block is placed. A higher y for the placed block would mean it's standing on top of something. A lower y means it's hanging and an equal y would result in 1 of 4 rotations based on x/z.

However I don't know if it's possible to get hand-coordinates while also getting the block to spawn right next to that block instead of replacing it. Otherwise you'd have to customarily do it through code.
