    This class is responsible for creating and positioning grid content items based on a specified prefab and item count. It instantiates the items and arranges them vertically with a specified offset.

    in favor of using SpectaclesUIKit's ScrollView component. See https://developers.snap.com/spectacles/spectacles-frameworks/spectacles-ui-kit/get-started for more details.

    Properties

    _debugDrawEnabled: boolean = false

    Shows visual debugging elements for scroll area bounds and content.

    _enableScrollInertia: boolean = true

    Enables physics-based scrolling where content continues moving after release with gradual deceleration and elastic bounce-back at boundaries."

    _scrollLimit: number = 0.3

    Controls how much content must remain visible. 0: Content can scroll completely out of view. 0.5: At least 50% of the content will remain in the visible area. 1: Content can't scroll out of view at all.

    api: Record<string, any>

    Generic object accessible by other instances of ScriptComponent. Use this object to store references to properties and methods that need to be accessible from other ScriptComponents.

    This property is no longer needed, you can use a reference to the ScriptComponent, including 'script', directly

    enabled: boolean

    If disabled, the Component will stop enacting its behavior.

    enableHorizontalScroll: boolean = false

    Allows content to be scrolled horizontally.

    enableScrollLimit: boolean = true

    When enabled, prevents content from scrolling beyond designated boundaries defined by the Scroll Limit.

    enableVerticalScroll: boolean = true

    Allows content to be scrolled vertically.

    isEnabledInHierarchy: boolean

    Returns true if this Component, its SceneObject, and all of that SceneObjects parents are enabled.

    isSynced: boolean = false

    Relevant only to lenses that use SpectaclesSyncKit when it has SyncInteractionManager in its prefab. If set to true before runtime, the ScrollView's position will be synced whenever a new user joins the same Connected Lenses session.

    name: string
    onContentLengthChanged: PublicApi<void> = ...
    sceneObject: SceneObject

    The SceneObject this component is on.

    scrollAreaBounds: vec2 = ...

    Defines the size of the interactive area in normalized local coordinates, where (1,1) uses the full component size.

    uniqueIdentifier: string
    updatePriority: number

    Accessors

    • get contentLength(): number

      Returns number

        the length of the content along the y-axis in local units relative to the ScrollView canvas.

      Returns void

    • get contentOffset(): Rect

      Returns Rect

      the offset to each content edge and the ScrollArea in world units relative to the canvas' rotation.

      Returns boolean

      if this class is ready to be used.

    • get overflow(): number

      Returns number

      the amount of content overflow along the y-axis in local units relative to the ScrollView's canvas.

    • get scrollAreaSize(): vec2

      Returns vec2

      the ScrollArea's size in local units relative to the ScrollView canvas.

    • get scrollColliderBounds(): vec2

      Returns vec2

      the ScrollArea collider's BoxShape's bounds.

    • set scrollColliderBounds(bounds: vec2): void

      Parameters

    • get scrollPercentage(): number

      Returns number

      the scroll percentage of the ScrollView (0=top of ScrollView, 1= bottom).

    Methods

    • Checks if both inputted content edges are fully visible in the ScrollArea.

      Parameters

      • xEdge: -1 | 0 | 1

        0 if not checking any x-axis edge, 1 for right edge, -1 for left edge.

      • yEdge: -1 | 0 | 1

        0 if not checking any y-axis edge, 1 for top edge, -1 for bottom edge.

      Returns boolean

    • Returns true if the object matches or derives from the passed in type.

      Parameters

      • type: string

      Returns boolean

    • Returns void

    • Returns void

    • Resets the content origin for the purpose of calculating scrollPercentage. Assumes that the ScrollView is currently at the top of content in the pooling use case.

      Returns void

    • Resets the inertia velocity in the case that the developer wants to stop physics upon certain events.

      Returns void

    • Parameters

      Returns void
