An Actor is any object that can be placed into a level. Actors are a generic Class that support 3D transformations such as translation, rotation, and scale. Actors can be created (spawned) and destroyed through gameplay code (C++ or Blueprints). In C++, AActor is the base class of all Actors.

There are several different types of Actors, some examples include: StaticMeshActor, CameraActor, and PlayerStartActor.

No matter the type of Actor you are using in your level - be it a light, a Static Mesh, a Particle System Emitter Actor, or anything else - you will need to know a few basics on how to create and manipulate them in your scenes.

This involves a few integral tasks: placing Actors, selecting Actors, positioning Actors, and modifying Actors. In other words, to create a level, Actors will be placed into a map, moved around to create an environment, and their properties will be modified to cause them to look or behave appropriately.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
