How do I use the same controls on multiple cards?
This lesson will show you how to share one set of controls across multiple cards. Using the same controls on multiple cards makes it much easier to make changes as you only have to update the controls in one place.
Navigate to Card 2
Using Groups to Share Controls
One approach to having the navigation controls show up on two cards would be to copy and paste the controls. While this might look right it creates a problem if I want to modify the navigation controls later on as I will have to update the controls on every single card!
Fortunately Rev provides a better way. With Rev you can share controls across multiple cards by using groups.
Grouping controls is easy. With the Edit tool active, just select the controls that you want to be in the same group. Here you can see that I've selected all of the navigation controls.
Name The Group
Place Group on Other Cards
If I go back to card 1 you can see that the x and y coordinates have been updated!
Now that you know how to share controls you should read up on the backgroundBehavior property. The backgroundBehavior property of a group affects whether or not it is added to new cards you create and where in the message hierarchy the group's script is placed.
