AnimationUtility.GetCurveBindings

描述

检索动画片段中的浮点曲线绑定。

Unity 有两种类型的动画：浮点曲线和对象引用曲线。浮点曲线是经典曲线，它随时间推移动画化浮点属性。对象引用曲线是随时间推移动画化对象引用属性的结构。

此方法返回浮点曲线绑定。有关对象引用曲线，请参阅 AnimationUtility.GetObjectReferenceCurveBindings。

using UnityEditor;
using UnityEngine;

// Editor window for listing all float curves in an animation clip
public class ClipInfo : EditorWindow
{
    private AnimationClip clip;

    [MenuItem("Window/Clip Info")]
    static void Init()
    {
        GetWindow(typeof(ClipInfo));
    }

    public void OnGUI()
    {
        clip = EditorGUILayout.ObjectField("Clip", clip, typeof(AnimationClip), false) as AnimationClip;

        EditorGUILayout.LabelField("Curves:");
        if (clip != null)
        {
            foreach (var binding in AnimationUtility.GetCurveBindings(clip))
            {
                AnimationCurve curve = AnimationUtility.GetEditorCurve(clip, binding);
                EditorGUILayout.LabelField(binding.path + "/" + binding.propertyName + ", Keys: " + curve.keys.Length);
            }
        }
    }
