Information

This example is affected by history changes in the story. Undoing or re-doing back to a passage containing this recipe has the potential to change its saved values.

Summary#

"Lock and Key: Variable" demonstrates how to create the effect of picking up a key and unlocking a door. In this example, the key is a variable ($key) and is initially set to the value false in the Start passage.

When the link (created using a <<linkreplace>> macro) "Pick up the key" is clicked, $key is changed to the value true and the door link changes from its initial response of "Locked Door" to a link to the passage Exit.
