6.2 - Adding a New Simulation Object Behavior (Creating an Actuator)

If you want to create a completely new type of actuator, subclass DtActuatorComponent (actCmpnt.h).

If you want to inherit functionality from one of the existing actuators, such as DtAutomotiveActuatorComponent, you can subclass that actuator.

In your actuator, you must do the following:

• Initialize the actuator
• Identify the type of component
• Create input ports to receive input from controllers
• Do what the actuator is intended to do.

The Modify Sim Component (modifySimComponent) example creates an actuator that simulates a vehicle that travels due north regardless of steering inputs, but at a speed regulated by the throttle input. It replaces the DtAutomotiveActuatorComponent.
