Explaining advanced features
In this section, we are going to explore how Unreal Engine copes with some of the common features of C++, such as casting and delegates.
Casting
In C++ – and other programming languages, casting is the process of converting a variable from one data type to another. It allows you to treat an object as a different type, which can be useful in various situations, such as when working with inheritance or interfacing with APIs. To cast in Unreal Engine, you use the Cast<T>() method. As an example, take a look at the following code:
APlayerCharacter* PlayerCharacter = Cast<APlayerCharacter>(Actor);
As you can see, we are trying to cast an Actor pointer to an APlayerCharacter type.
In Unreal Engine, the Cast<T>() function is a safe way to cast pointers to a specific class type, as your code will return nullptr instead of crashing when the cast itself fails.
Casting in Unreal Engine should be approached...
