Class Description

The ActionDelta object tracks changes made on a parameter that is part of a reference model. Every ActionDelta contains one or more ActionDeltaItem objects, each of which represents a single change, or modification, to a referenced parameter. Each ActionDelta object has a specific type (see siModificationDeltaType) and each ActionDeltaItem it contains is of the same type.

ActionDeltas are stored in the Delta and are accessible via Delta::GetActionDeltas. To add a new ActionDelta to an existing Delta object, use Delta::AddAction.

Since:
6.0

Adds a new ActionDeltaItem of type siModificationDeltaConstraint to an ActionDelta created with Delta::AddAction.

The ActionDelta should be of type siModificationDeltaConstraint to use this function (see siModificationDeltaType for a list of ActionDelta types).

Parameters:
in_preset The type of constraint to add.
in_cnsned An array of references to X3DObject elements that will be constrained (see Constraint::GetConstrained).
in_cnsning An array of references to X3DObject elements that will act as constrainers (see Constraint::GetConstraining).
in_bComp Compensation mode: true to turn compensation on.
in_offsetCnsned Optional offset which is applied in translation on the constrained object. The offset is used for Distance and Position constraints.
in_offsetCnsning Optional offset applied on the constraining object for Distance, Position, Surface and Trajectory constraints. The offset will be applied in rotation for the Orientation constraint, in translation for the Direction constraint and in scaling for the Scaling constraint.
Returns:
An array of references to the new ActionDeltaItems (one for each parameter now being driven by the constraint)
