Detailed Description

Run a collection of actions together (in parallel).

This action acts on behalf of other actions as a proxy, executing actions together until every action has completed. If an action in the group has a duration less than the group's total duration, the action completes, then idles until the group completes the remaining actions.

Remarks: This action is not reversible, but the child actions may be reversible. Consult the documentation for the action in question for implementation details.

Member Typedef Documentation

◆ container_iterator

typedef container_type::iterator nom::GroupAction::container_iterator

private

Definition at line 95 of file GroupAction.hpp.

◆ container_type

typedef std::vector<group_action> nom::GroupAction::container_type

private

Remarks: A std::vector container seems most appropriate here because of the contiguous memory access, for lack of any other special needs, i.e.: fast front/back iteration or fast expansion time.

Constructor & Destructor Documentation

◆ GroupAction()

nom::GroupAction::GroupAction ( const action_list & actions )

Run a collection of actions together (in parallel).

Parameters

actions The group of actions to execute; NULL actions are valid.

Member Function Documentation

◆ clone()

virtual std::unique_ptr< IActionObject > nom::GroupAction::clone ( ) const

overridevirtual

Create a deep copy instance of the action.

Remarks: A cloned instance is created using the action's attributes at the time of construction. External resources of the action – i.e.: nom::Sprite – are not modified, and you may need to reset the state appropriately if the action has been ran previously.

Implements nom::IActionObject.

◆ next_frame()

virtual IActionObject::FrameState nom::GroupAction::next_frame ( real32 delta_time )

overridevirtual

Play the action forward in time by one time step.

Parameters

delta_time Reserved for application-defined implementations.

Note: This method should not normally need to be called externally! Exceptions might include: a) implementing a new action; b) advanced debugging

See also: nom::DispatchQueue

Implements nom::IActionObject.

◆ pause()

virtual void nom::GroupAction::pause ( real32 delta_time )

overridevirtual

Freeze the action's internal state.

Parameters

delta_time Reserved for application-defined implementations.

Note: This method should not normally need to be called externally! Exceptions might include: a) implementing a new action; b) advanced debugging

See also: nom::DispatchQueue

Implements nom::IActionObject.

◆ prev_frame()

virtual IActionObject::FrameState nom::GroupAction::prev_frame ( real32 delta_time )

overridevirtual

Play the action backwards in time by one time step.

Parameters

delta_time Reserved for application-defined implementations.

Note: This method should not normally need to be called externally! Exceptions might include: a) implementing a new action; b) advanced debugging

Remarks: Not all actions are reversible – see the action's documentation for its implementation details.

See also: nom::ReversedAction

Implements nom::IActionObject.

◆ release()

virtual void nom::GroupAction::release ( )

overridevirtual

Free externally referenced resources held by the action.

Note: This method should not normally need to be called externally! Exceptions might include: a) implementing a new action; b) advanced debugging

See also: nom::RemoveAction

Implements nom::IActionObject.

◆ resume()

virtual void nom::GroupAction::resume ( real32 delta_time )

overridevirtual

Resume the internal state of the action.

Parameters

delta_time Reserved for application-defined implementations.

Note: This method should not normally need to be called externally! Exceptions might include: a) implementing a new action; b) advanced debugging

See also: nom::DispatchQueue

Implements nom::IActionObject.

◆ rewind()

virtual void nom::GroupAction::rewind ( real32 delta_time )

overridevirtual

Reset the internal state of the action back to its initial starting values.

Parameters

delta_time Reserved for application-defined implementations.

Note: This method should not normally need to be called externally! Exceptions might include: a) implementing a new action; b) advanced debugging

See also: nom::RepeatForAction, nom::RepeatForeverAction

Implements nom::IActionObject.

◆ set_speed()

virtual void nom::GroupAction::set_speed ( real32 speed )

overridevirtual

Set the speed factor of the child actions.

Remarks: This has no effect on the parent (this object).

Reimplemented from nom::IActionObject.

◆ set_timing_curve()

virtual void nom::GroupAction::set_timing_curve ( const IActionObject::timing_curve_func & mode )

overridevirtual

Set the timing mode of the child actions.

Remarks: This has no effect on the parent (this object).

See also: nom::IActionObject::timing_curve_func

Reimplemented from nom::IActionObject.
