Unity 将子节点添加到 blendtree

Question

我正在尝试制作一个脚本，该脚本将接收动画列表并自动将它们添加到混合树中。我查看了混合树 API 并想出了这个：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
using UnityEditor.Animations;

public class AnimationSwitcher : MonoBehaviour
{
    public List<Motion> animations;
    public Animator animator;




    public BlendTree blendTree;

    public void addMotions()
    {
        for (int i = 0; i < animations.Count; i++)
        {
            blendTree.AddChild(animations[i]);
        }
    }
    
}

我知道我必须使用 animator 组件，但是对于如何使用它来添加 blendtree 子组件，我无法获得易于阅读的答案。我试过在编辑器中分配混合树，但也没有用

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
using UnityEditor.Animations;

public class AnimationSwitcher : MonoBehaviour
{
    public List<Motion> animations;
    public AnimatorController animator;
    private BlendTree blendTree;

    void Start()
    {
        animator.CreateBlendTreeInController("Active", out blendTree);
        blendTree.AddChild(animations[0]);
    }


    public void addMotions()
    {
        for (int i = 0; i < animations.Count; i++)
        {
            blendTree.AddChild(animations[i]);
        }
    }
   
}
