Changing direction

In this section, we will implement the logic to change the target's direction periodically. This will result in a target that moves back and forth between two points regularly, much like a shooting gallery target:

1. Right-click in an empty space of the EventGraph to open the context menu and search for custom event. Select the Add Custom Event option. Rename the event ChangeDirection:

3. Drag the Direction variable from the My Blueprint panel and drop it into the EventGraph. Choose the Get Direction option to create a node.
4. Drag from the output pin of the Direction node and drop it into an empty space. Type an asterisk (*) in the search field and select the Multiply node.
5. The previous step...
