The Event Track can be used to call Custom Events that can execute Blueprint Scripts inside of multiple Blueprints.
When the Custom Event is called, any script attached to it will also be executed and can be used for any number of scenarios based on your needs.
When using the Event Track and calling a Custom Event, you can also pass through your own Custom Structs, which can be used to update the variables contained therein.
This can be useful in situations where you want to update other variables during the playback of a Level Sequence.
In this example, we use the Event Track to call an Event with a Custom Struct that is used to move an object in the Level Blueprint and turn off/on a Point Light in another Blueprint.
