TransformSceneHandle

Description

Handle to read position, rotation and scale of an object in the Scene.

TransformSceneHandle are read-only.

A TransformSceneHandle is a safe handle on a TransformAccess. The Animator used to create this handle manages the validity of this handle.

        // Log the local position.
        var position = handle.GetLocalPosition(stream);
        Debug.LogFormat("Position: {0}", position);

        // Log the local rotation (converted from euler).
        var rotation = handle.GetLocalRotation(stream);
        Debug.LogFormat("Rotation: {0}", rotation.eulerAngles);

        // Log the local scale.
        var scale = handle.GetLocalScale(stream);
        Debug.LogFormat("Scale: {0}", scale);
    }
