Sequence Class

Extends MonoBehaviour
Implements Oculus.Interaction.IActiveState, Oculus.Interaction.ITimeConsumer
Chains together a number of IActiveStates into a sequence.
The Sequence._stepsToActivate field contains an optional list of IActiveState's which must be 'activated' in order. The sequence can progress from Step N to N + 1 when: ActivationStep.MinActiveTime <= "Time step N active for" <= ActivationStep.MaxStepTime, and:
Step N just became inactive OR Step N is the last step OR Step N+1 is active
Note that once the sequence has moved on to the next step, the previous step does not need to remain active. Each step has three fields: ActivationStep.ActiveState: The IActiveState that is used to determine if the conditions of this step are fulfilled ActivationStep.MinActiveTime: How long (in seconds) the IActiveState of this step must be contiguously active before moving on to the next step. If the ActiveState drops out of being active for even a single frame the countdown is reset. ActivationStep.MaxStepTime: If the elapsed time that the sequence is spent waiting for this step to reach its MinActiveTime exceeds this value then the whole sequence is reset back to the beginning.
Once all steps are complete the Sequence.Active becomes true. It will remain true as long as RemainActiveWhile is true. If _remainActiveCooldown > 0, Sequence.Active will remain active even after RemainActiveWhile becomes false until the cooldown timer is met. The timer is reset if RemainActiveWhile becomes true again.

Properties

Active : bool
[Get]
Implements IActiveState.Active, in this case indicating whether the described sequence of IActiveStates has been "recognized" as having occurred with acceptable order and timing.
Signature 
bool Oculus.Interaction.PoseDetection.Sequence.Active
CurrentActivationStep : int
[Get]
Returns the index of the step in _stepsToActivate whose conditions are waiting to be activated.
If Active is true, this value will be set to the size of _stepsToActivate. If _stepsToActivate has no steps, this property will be 0.
Signature 
int Oculus.Interaction.PoseDetection.Sequence.CurrentActivationStep

Protected Methods

virtual void Oculus.Interaction.PoseDetection.Sequence.Awake()
Returns

Start ()
Signature 
virtual void Oculus.Interaction.PoseDetection.Sequence.Start()
Returns
void
Update ()
Signature

Methods

InjectOptionalRemainActiveWhile ( activeState )
Sets the IActiveState for the optional "remain active while" capability (which allows a Sequence to remain active pending the inactivity of the given IActiveState rather than resetting after activation) for a dynamically instantiated Sequence.
This method exists to support Interaction SDK's dependency injection pattern and is not needed for typical Unity Editor-based usage.
Signature 
void Oculus.Interaction.PoseDetection.Sequence.InjectOptionalRemainActiveWhile(IActiveState activeState)
Parameters
activeState: IActiveState
Returns
void
InjectOptionalStepsToActivate ( stepsToActivate )
Sets the ActivationSteps for a dynamically instantiated Sequence.
This method exists to support Interaction SDK's dependency injection pattern and is not needed for typical Unity Editor-based usage.
Signature 
void Oculus.Interaction.PoseDetection.Sequence.InjectOptionalStepsToActivate(ActivationStep[] stepsToActivate)
Parameters
stepsToActivate: ActivationStep []
Returns
void
InjectOptionalTimeProvider ( timeProvider )
Signature 
void Oculus.Interaction.PoseDetection.Sequence.InjectOptionalTimeProvider(Func< float > timeProvider)
Parameters
timeProvider: Func< float >
Returns
void
SetTimeProvider ( timeProvider )
Implements ITimeConsumer.SetTimeProvider(Func<float>).
Sets the time provider for this sequence, allowing for the default time provider (Unity's built-in Time.time) to be overridden with custom behavior to enable pausing, time dilation, etc.
Signature 
void Oculus.Interaction.PoseDetection.Sequence.SetTimeProvider(Func< float > timeProvider)
Parameters
timeProvider: Func< float >  The new time provider to be used by this instance.
Returns
void

Inner Class

ActivationStep Class

Wrapper for IActiveStates which are to be incorporated into a Sequence.
This type is exclusively intended to be used as part of a Sequence, and details of its intended usage and expected behavior are documented in the remarks for that type.

Constructors

ActivationStep ()
Basic constructor for ActivationStep.
Should not be called directly.
This empty constructor is typically invoked by Unity logic when deserializing a serialized-and-saved ActivationStep.
Signature 
Oculus.Interaction.PoseDetection.Sequence.ActivationStep.ActivationStep()
ActivationStep ( activeState , minActiveTime , maxStepTime )
Constructor for constructing new ActivationSteps programmatically.
Signature 
Oculus.Interaction.PoseDetection.Sequence.ActivationStep.ActivationStep(IActiveState activeState, float minActiveTime, float maxStepTime)
Parameters
activeState: IActiveState  The IActiveState to be assigned to ActiveState
minActiveTime: float  The float value to be assigned to MinActiveTime
maxStepTime: float  The float value to be assigned to MaxStepTime

Fields

MaxStepTime : float
The maximum amount of time a Sequence can remain in this ActivationStep (without proceeding to the next one) before the Sequence "fails out" and must start again from the beginning.
For a detailed overview of the function of ActivationSteps and their role in Sequences, please see the documentation for Sequence.
Signature 
float Oculus.Interaction.PoseDetection.Sequence.ActivationStep.MaxStepTime
MinActiveTime : float
The minimum amount of time for which ActiveState must be active in order for this ActivationStep to be considered completed.
For a detailed overview of the function of ActivationSteps and their role in Sequences, please see the documentation for Sequence.
Signature 
float Oculus.Interaction.PoseDetection.Sequence.ActivationStep.MinActiveTime

Properties

ActiveState : IActiveState
[Get]
The IActiveState whose activation is the condition for completing an ActivationStep of the containing Sequence.
For a detailed overview of the function of ActivationSteps and their role in Sequences, please see the documentation for Sequence.
Signature 
IActiveState Oculus.Interaction.PoseDetection.Sequence.ActivationStep.ActiveState

Methods

Start ()
Method invoked when a Sequence "moves into" this ActivationStep.
This method should only ever be invoked by the internal logic of its containing Sequence.
Signature 
void Oculus.Interaction.PoseDetection.Sequence.ActivationStep.Start()
Returns
void
