There is two ways to interpolate the rotation of a transform :

• UBTween.Rotation will take the shorstest path to the target Rotation. It’s not possible to make roation of more than 180d.
• UBTween.ExactRotation will be able to make rotation of more than 180d.

Supported Objects:

Target	Value changed (Ref Global)	Value changed (Ref Local)
Transform	Transform.rotation	Transform.localRotation
RectTransform	RectTransform.rotation	RectTransform.localRotation

Rotation

Use Current Rotation As Start :

UBTween.Rotation(
    transform,                                  // Target Object
    Quaternion.AngleAxis(90f, Vector3.forward), // End Rotation
    1f);                                        // Duration

Using float will use UBTween.RotationAxis by default, (you can change the value to suit your needs):

UBTween.Rotation(
    transform,  // Target Object
    90f,        // Target Angle
    1f);        // Duration

Specify Start Rotation :

UBTween.Rotation(
    transform,                                      // Target Object
    Quaternion.AngleAxis(90f, Vector3.forward),     // Start Rotation
    Quaternion.AngleAxis(-90f, Vector3.forward),    // End Rotation
    1f);                                             // Duration

Using float will use UBTween.RotationAxis by default, (you can change the value to suit your needs):

UBTween.Rotation(
    transform,      // Target Object
    90f,            // Start Angle
    -90f,           // End Angle
    1f);            // Duration

ExactRotation :

UBTween.ExactRotation(
    transform,              // Target Object
    transform.rotation,     // Start Rotation
    360f,                   // Angle
    Vector3.up,             // Axis
    1f);                    // Duration

UBTween.ExactRotation(
    transform,      // Target Object
    360f,           // Angle
    Vector3.up,     // Axis
    1f);            // Duration

Referencial :

It’s possible to whether translate the local rotation or the global position by using the Ref Enum.

Target	Value changed (Ref Global)	Value changed (Ref Local)
Transform	Transform.position	Transform.localPosition
RectTransform	RectTransform.position	RectTransform.localPosition

From Current

UBTween.Position(
    transform,                  // Target Object
    new Vector3(0f, 1f, 0f),    // End Position
    1f,                         // Duration
    Ref.Global);                // Ref

From Specific Start

UBTween.Position(
    transform,                  // Target Object
    new Vector3(-1f, .5f, 0f),  // Start Position
    new Vector3(1f, .5f, 0f),   // End Position
    1f,                         // Duration
    Ref.Local);                 // Referencial

Gif Code :

UBTween.Sequence sequence = new UBTween.Sequence()
{
    // 0f To 180f
    UBTween.ExactRotation(transform, 180f, .5f)
        .SetEase(EaseType.InBack),

    UBTween.ExactRotation(transform, 180f, 360f, 1f)
        .SetEase(EaseType.OutElastic)
        .SetDelay(.5f),

}.Start().SetLoop();
