In Unreal Engine, all the objects that can be placed in a level are referred to as Actors. In a movie, an actor would be a human playing a character, but in UE4, every single object you see in your level, including walls, floors, weapons, and characters, is an Actor.

Every Actor must have what's called a Transform property, which is a collection of three things:

• Location: A Vector property signifying the position of that Actor in the level in the X, Y, and Z axis. A vector is simply a tuple with three floating point numbers, one for the location of the point in each axis.
• Rotation: A Rotator property signifying the rotation of that Actor along the X, Y, and Z axis. A rotator is also a tuple with three floating point numbers, one for the angle of rotation in each axis.
• Scale: A Vector property signifying the scale (meaning size) of that Actor in the level in the X, Y, and Z axis. This is also a collection of three floating point numbers...
