DtTurretActuatorComponent provides a simple model of a rotating turret that knows how to drive the articulating parts objects of the local state repository.
End User Description: The turret actuator updates the articulated part specified in its component descriptor, based on slew data it receives. It expects an input (via a mySlewPort) of a slew amount between -1. and +1.
Developer Description: The tick() function first checks to see if dT is 0.0. If it is, it just returns. Otherwise, it looks up the DtArticulatedPartStateRepository object kept by the entity to maintain state for the turret using DtAttachmentManager::findPartByType with the turret art part type from the process state repository as the argument. The current angle of the turret (with respect to whatever is it attached to) is retrieved from the DtArticulatedPartStateRepository which represents the turret by going through the kinematic state to get the "psi" component of the parent orientation. The slewRate to use is calculated using: the value on the slew port * myMaxSlewRate The new turret angle is calculated as: the current angle + (slew rate * dT) The angle is then constrained to be between 0.0 and 2 * PI using the VR-Link utility function DtModPerLo(). The new angle is then stored in the kinematic state of the rotating body.
