Get the ItemFrame a player is looking at.

I'm currently looking for a way to display players information about what is in an ItemFrame for my ItemFrameShops plugin. I'm hoping to do this using the scoreboard and a repeating task, since I've allready used right click, crouch right click, left click and crouch left click.

For this I will need to know which frame the player is looking at. I've found this: https://forums.bukkit.org/threads/find-blockface-player-is-targeting.145903/ which would allow me to get the itemframe, but I feel like there must be a more simple solution.

Or is there any other way I could provide the user with the information? I don't want them to have to use a command.

I'm still looking for a solution here Anyone? Any idea?

Use BlockIterator. For each block check if it's type is AIR then continue, otherwise it's the block the player is looking at.

 

A ItemFrame is an Entity, not a Block.
