Public Constructors

public AnchorNode ()

Create an AnchorNode with no anchor.

public AnchorNode ( Anchor anchor)

Create an AnchorNode with the specified anchor.

Parameters

anchor

the ARCore anchor that this node will automatically position itself to.

Public Methods

public Anchor getAnchor ()

Returns the ARCore anchor if it exists or null otherwise.

public boolean isSmoothed ()

Returns true if the transformations are interpolated or false if they are applied immediately.

public boolean isTracking ()

Returns true if the ARCore anchorâs tracking state is TRACKING.

public void onUpdate ( FrameTime frameTime)

AnchorNode overrides this to update the node's position to match the ARCore Anchor's position.

Parameters

frameTime

provides time information for the current frame

public void setAnchor ( Anchor anchor)

Set an ARCore anchor and force the position of this node to be updated immediately.

Parameters

anchor

the ARCore anchor that this node will automatically position itself to.

public void setLocalPosition ( Vector3 position)

Set the local-space position of this node if it is not anchored. If the node is anchored, this call does nothing.

Parameters

position

The position to apply.

Set the local-space rotation of this node if it is not anchored. If the node is anchored, this call does nothing.

Parameters

rotation

The rotation to apply.

public void setSmoothed (boolean smoothed)

Set true to smooth the transition between the nodeâs current position and the anchor position. Set false to apply transformations immediately. Smoothing is true by default.

Parameters

smoothed

Whether the transformations are interpolated.

public void setWorldPosition ( Vector3 position)

Set the world-space position of this node if it is not anchored. If the node is anchored, this call does nothing.

Parameters

position

The position to apply.

public void setWorldRotation ( Quaternion rotation)

Set the world-space rotation of this node if it is not anchored. If the node is anchored, this call does nothing.

Parameters

rotation

The rotation to apply.
