Actors are the essential objects of the scenes. You can place them into a level to build game environment, setup a lighting and create a gameplay. Every Actor is linked to the parent actor (except the Scene actors which are root of the hierarchy) and can have child actors (tree hierarchy). Actors have own 3D transformation (translation, rotation and scale) and inherit the parent actor transformation. You can attach C# scripts to the actors and spawn/destroy them at runtime.
This documentation page contains link to all tutorials related to working with actors and references to all actor types.
