Unreal Engine 4.x Scripting with C++ Cookbook - Second Edition

How it works...

Inside our GameMode header, we declare a type of delegate that doesn't take any parameters, called FStandardDelegateSignature. We then create an instance of the delegate as a member of our GameModeBase class.

We add a PointLight component inside of the DelegateListener so that we have a visual representation of the delegate being executed that we can turn on later on. In the constructor, we initialize our PointLight, and then disable it. To make it easier to see, we also change the color to blue.

We override BeginPlay. We first call the parent class's implementation of BeginPlay(). Then, we get the game world, retrieving the GameMode class using GetGameMode(). Casting the resulting AGameMode* to a pointer of our GameMode
