How do you lock and/or unlock a door in Twine?
As discussed on the main page for this section, this is done using variables. This page will take you through the process of creating a locked door and show you how it might be unlocked. In the case of a encountering a locked door, if you don't have the item (e.g., the key) you will get one message (e.g., This door is locked. Looks like you need to go find a key!) and something happens or doesn't happen (e.g., the door stays locked).
On the other hand, if you do you may get a different message (e.g., You try your key in the door and the locks clicks.) have the item happens (e.g. The door opens with an ominous creak.). The simple 4-passage IF pictured just below is an example of the Locked Door scenario. You can also find the game itself at the bottom of this page.
A locked door, a key, and a passage of death!
How does this work?
How does this work?
To create a locked door story, you need a starting point in your story (typically the first passage--titled The Quest below) where the key variable is set to false, as you can see below.
(set: $key to false)
In this story, if someone goes to the Passage titled The key to success they'll encounter this variable information:
(set: $key to true)
This means that as soon as they enter the room they are given the key. In this case, they also get the following message: "As you enter the dark room you trip over something. Dang! You reach down and discover a key. Hmmmm, where could you use this?"
If the player goes to the Passage titled room 1: A locked door with the key it will cause the code below to trigger a message: "You put the key in the mysterious door and Blingo!!"
(if: ($key is true))
[you put the key in the mysterious door and Blingo!!]
However, if they don't have the key they get a different message: "This door seems pretty locked to me. Better go find a key!
(else:) [This door seems pretty locked to me. Better go find a key!]
As mentioned, this story also may result in death via the passage titled A quick death (I'd hope your own story would not be quite so obvious!) via the code below:
=><=
###Game over.
=><=
Looks like this was a really bad room to visit. The good news is that you can try again!

See how all of this works together in the embedded IF just below.
