# AnimatorTransitionInfo

> Information about the current transition on a specific state machine layer.

## Definition

* **Type:** Struct
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.AnimationModule

```csharp
public struct AnimatorTransitionInfo
```

## Remarks

Use [Animator.GetAnimatorTransitionInfo](/engine/6000.7/script-reference/unityengine/animator/getanimatortransitioninfo.md) to access transition information during playmode. Use this information to, for example, check the current transition and measure its progress. You can use the weight of the target state to measure the progress of a transition.

This struct is not related to [AnimatorTransition](/engine/6000.7/script-reference/unityeditor/animations/animatortransition.md) which is only available in the Editor and is used to build state machine transitions from code.

## Examples

```csharp
using UnityEngine;

// MonoBehaviour that sets the IK position and weight of the right hand when the character transitions to a "Grab" animation
// state.
[RequireComponent(typeof(Animator))]
public class GrabBehaviour : MonoBehaviour
{
    private Animator m_Animator;

    public Transform grabTarget;

    void Start()
    {
        m_Animator = GetComponent<Animator>();
    }

    void OnAnimatorIK(int layerIndex)
    {
        float ikWeight;

        var transitionInfo = m_Animator.GetAnimatorTransitionInfo(0);
        if (transitionInfo.IsName("Locomotion -> Grab"))
        {
            // When the character transitions from "Locomotion" to "Grab" state, do not immediately 
            // set the IK weight from 0 to 1 to avoid the hand instantly snapping to the target.
            // The IK weight changes at the same rate as the animation state. For example, when the
            // transition is halfway through, the IK weight is 0.5.
            ikWeight = transitionInfo.normalizedTime;
        }
        else
        {
            // The IK weight is 0 when the "Locomotion" state is active and 1 when the "Graph" state is active.
            ikWeight = m_Animator.GetCurrentAnimatorStateInfo(0).IsName("Grab") ? 1f : 0f;
        }

        m_Animator.SetIKPositionWeight(AvatarIKGoal.RightHand, ikWeight);
        if (ikWeight > 0f)
        {
            m_Animator.SetIKPosition(AvatarIKGoal.RightHand, grabTarget.position);
        }
    }
}
```
