Seltani coding help

I want to make an exit that’s only obvious if you move something around, and the room description should update to note this. You can move it back if desired, and since it would make sense for this object to block entry, you should be able to move it around from the room the exit goes to (so I guess this means I should make the variable tracking it a realm property). Can someone walk me through doing this? I’m not too read up on how Seltani works. Screenshots of how it would look in the build pane would be helpful.

I can’t give you screenshots, but the basic plan is to use conditional text.

[$if realm.objmoved]
You see a [door], and a movable thing.
You see a movable thing.

The worked example section of the docs covers this.
