AnimationUtility.GetCurveBindings

切换到手册
public static EditorCurveBinding[] GetCurveBindings (AnimationClip clip);

描述

返回当前存储在剪辑中的所有浮点曲线绑定。

回答以下问题：“哪些浮点属性由剪辑进行动画化？”

Unity 具有两种类型的动画：浮点和对象引用。浮点曲线是一种随着时间的推移对浮点属性进行动画化的经典曲线。对象引用“曲线”是一种随着时间的推移对对象引用属性进行动画化的构造。

此方法仅返回浮点曲线绑定。请参阅 AnimationUtility.GetObjectReferenceCurveBindings 以了解对象引用曲线。

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);
            }
        }
    }
}
