Scope

By default, a node will be scoped to all instances of it's module across all pages of your site.

For example, a Video:OnEnded Broadcast node will trigger when any video on any page ends.

We can scope a node to a specific instance of a module by using the About field on the node.

Example

We have a site with three pages:

A Welcome Page

A Screening Page

An End Page

We want to build a flow that will send the user to the End page when the video on Screening page ends. But if the user watches the trailer on the Welcome page, we do not want to send them to the End page.

Let's build that flow:

This will work to send the user to the End page when the video ends. However, this will send the user to the End page when any video ends.

We want to tell the Flow Controller to only pressurize this flow when the specific video on the Screening page ends. We can do this by specifying the instance in the About field of the Video:ended node.

In the Page Editor, select the Video Player module on the Screening page, and click the Copy Id button.

Paste that value into the About field on the Video:ended node.

Now, this Video:ended Broadcaster node will only pressurize when that specific video ends.
