Creating game actor classes

The term game actor classes refers to the AActor, APawn, and ACharacter classes. These three classes are used to instantiate game actors that will be placed in the game levels, as follows:

• AActor is the base class for creating a wide range of objects, such as buildings, spawn points, portals, vehicles, characters, and so on. We will extend this class to create ADefenseTower, AWeapon, and AProjectile classes.
• APawn is a subclass of AActor that is used to create non-character, player-controllable actors (not characters) that accept and react to player inputs—racing cars, for example.
• ACharacter extends the APawn class for creating characters. A character can not only accept user inputs and moves but also has at least one skeletal mesh and the character state animations, such as idle, walk, run, attack, die, and so on. We will extend this class to create a new APlayerAvatar class.
