Chapter 5. Handling Events and Delegates

Unreal uses events for notifying classes about things that happen in the game world in an efficient manner. Events and delegates are useful to ensure that these notifications can be issued in a way which minimizes class coupling, and allows arbitrary classes to subscribe to be notified.

We will cover the following recipes in this chapter:

• Handling events implemented via virtual functions
• Creating a delegate that is bound to a UFUNCTION
• Unregistering a delegate
• Creating a delegate that takes input parameters
• Passing payload data with a delegate binding
• Creating a multicast delegate
• Creating a custom Event
• Creating a Time of Day handler
• Creating a respawning pickup for an First Person Shooter
