When developing a server I found that we had a lot of item frames that needed to be made invisible. The default Minecraft command /execute as @e[type=item_frame,distance=0..4] run data merge entity @s {Invisible:1b} exists, but that's a) a bit cumbersome, and b) only available to those with op permissions.
So, I made this.
There's just the one command: /setframevisible <true/false> [distance] [limit?]. The true/false is for whether or not you want the nearby frames to be visible or not. distance is for how far away you want to change item frames, and limit is an optional number of item frames to change, ordered by distance.
/setframevisible false 10 will set all item frames within 10 blocks to invisible.
/setframevisible true 30 5 will set the nearest 5 item frames within 30 blocks to visible.
Because an important part of this was giving out permissions without op perms, I needed to add permissions. Very handily, I added a single perm for the single command.
