Interactable Class

Definition

Uses input and action data to declare a set of states Maintains a collection of themes that react to state changes and provide sensory feedback Passes state information and input data on to receivers that detect patterns and does stuff.

Interactable()

Fields

CanDeselect

Can the user deselect a toggle? A radial button or tab should set this to false

CanSelect

Is the interactive selectable? When a multi-dimension button, can the user initiate switching dimensions?

clickTime

A click must occur within this many seconds after an input down

clickValidTimer
dimensionIndex
Dimensions

A way of adding more layers of states for controls like toggles. This is capitalized and doesn't match conventions for backwards compatibility (to not break people using Interactable). We tried using FormerlySerializedAs("Dimensions) and renaming to "dimensions", however Unity did not properly pick up the former serialization, so we maintained the old value. See https://github.com/microsoft/MixedRealityToolkit-Unity/issues/6169

dragStartPosition

The position of the controller when input down occurs. Used to determine when controller has moved far enough to trigger gesture

focusingPointers
forceUpdate
globalFeedbackClickTime

Amount of time to "simulate" press states for interactions that do not utilize input up/down such as voice command This allows for visual feedbacks and other typical UX responsiveness and behavior to occur

globalTimer
handlers
isGlobal
lastState
OnClick

Base onclick event

pressingInputSources
rollOffTimer
VoiceCommand

This string keyword is the voice command that will fire a click on this Interactable.

InteractableEvents

List of events added to this interactable

IsDisabled
Obsolete.

Is disabled

IsEnabled

Defines whether the Interactable is enabled or not internally This is different than the Enabled property at the GameObject/Component level When false, Interactable will continue to run in Unity but not respond to Input.

IsGlobal

If true, this Interactable will listen globally for any IMixedRealityInputHandler input events. These include general input up/down and clicks. If false, this Interactable will only respond to general input click events if the pointer target is this GameObject's, or one of its children's, collider.

IsInteractive

State that corresponds to no focus,and finger is up. Currently not controlled by Interactable directly

IsTargeted

Targeted means the item has focus and finger is up Currently not controlled by Interactable directly

IsToggleButton
Obsolete.

True if Selection is "Toggle" (Dimensions == 2)

ResetOnDestroy

If true, when this component is destroyed, active themes will reset their modified properties to original values on the targeted GameObjects. If false, GameObject properties will remain as-is.

Allows for switching colliders without firing a lose focus immediately for advanced controls like drop-downs

StateManager

States

ScriptableObject to reference for basic state logic to follow when interacting and transitioning between states. Should generally be "DefaultInteractableStates" object

VoiceCommand

This string keyword is the voice command that will fire a click on this Interactable.
