Description

ASim3dActor is an abstract class that you can use as a base class for user-defined Unreal Engine® C++ or blueprint actors.

The base classes are inherently synchronized during co-simulation with a Simulink® model. Additionally, the Simulation 3D Actor Transform Set block can control the base class. To extend behavior of ASim3dActor, you can use the message interface functions to override the class methods so they send and receive messages to and from a model.

ASim3dActor is included in the Simulink 3D Animation™ Interface for Unreal Engine Projects. For information about the support package, see Customize Scenes in Unreal Engine for 3D Simulations.
