Hi. I'm having some trouble as I'm using the online version, and cannot figure out how to make a hidden exit visible. Thank you!

Edit: I figured it out on my own. I'm going to move my character to a second room instead of turning off the lights. If you've got any other ways to handle this, I'd still like to see for future reference

Give it a name so you can reference it. Then set it "visible" attribute to true. In code it looks like this:

my_exit.visible = true
