Avatar Mask主要用於動畫層融合。例如說，邊跑邊舉起東西，這個實際上就是下半身播放跑步動畫，上半身播放舉起動畫，所謂的Avatar Mask就是播放動畫時讓身體的某些部位不起作用(即不播放動畫)

 

1.添加一個新的動畫層

其中Empty是一個空的動畫，同時添加一個Trigger型參數wave

 

TestAnimator.cs

using UnityEngine;

public class TestAnimator : MonoBehaviour {

    //------------------------------------------外部
    public float Move = 0;
    public bool IsDying = false;

    //------------------------------------------內部
    private Animator animator;

    //常數
    private int baseLayerIndex;
    private int idleStateHash;
    private int runStateHash;
    private int dyingStateHash;
    private string movePara;
    private string isDyingPara;
    private string wavePara;

    void Start ()
    {
        animator = GetComponent<Animator>();

        baseLayerIndex = animator.GetLayerIndex("Base Layer");
        idleStateHash = Animator.StringToHash("Base Layer.Idle");
        runStateHash = Animator.StringToHash("Base Layer.Run");
        dyingStateHash = Animator.StringToHash("Base Layer.Dying");
        movePara = "move";
        isDyingPara = "isDying";
        wavePara = "wave";
    }
    
    void Update ()
    {
        //------------------------------------------播放動作
        animator.SetFloat(movePara, Move);
        if (IsDying)
        {
            animator.SetBool(isDyingPara, true);
            IsDying = false;
        }

        //------------------------------------------動作恢復
        AnimatorStateInfo stateInfo;
        int fullPathHash;

        //BaseLayer
        stateInfo = animator.GetCurrentAnimatorStateInfo(baseLayerIndex);
        if (!animator.IsInTransition(baseLayerIndex) && stateInfo.normalizedTime >= 1)
        {
            fullPathHash = stateInfo.fullPathHash;
            if (fullPathHash == dyingStateHash)
            {
                animator.SetBool(isDyingPara, false);
            }
        }
    }

    public void SetDying(bool state)
    {
        if (animator)
        {
            animator.SetBool(isDyingPara, state);
        }
    }

    public void TriggerWave()
    {
        if (animator)
        {
            animator.SetTrigger(wavePara);
        }
    }

    public void ActionCallBack(string s)
    {
        if (s == "dyingStart")
        {
            Debug.Log("111");
        }
        else if (s == "dying")
        {
            Debug.LogWarning("222");
        }
        else if (s == "dyingEnd")
        {
            Debug.LogError("333");
        }
    }
}

 

NewBehaviourScript.cs

using UnityEngine;

public class NewBehaviourScript : MonoBehaviour {

    public TestAnimator testAnimator;
        
    void Update ()
    {
        if (Input.GetKeyDown(KeyCode.Q))
        {
            testAnimator.Move = 1;
        }
        if (Input.GetKeyDown(KeyCode.W))
        {
            testAnimator.TriggerWave();
        }
    }
}

 

效果如下。按下Q，播跑步動畫，再按下W，覆蓋為招手動畫。可以試着將這兩個層的位置換一下。可以看出，動畫層越后優先級越高；同時還受動畫層的權重影響。

 

2.創建一個Avatar Mask並添加到動畫層中

如下圖2，表示該動畫層中只有上半身起作用

 

效果如下。按下Q，播跑步動畫，再按下W，上半身播招手動畫。
