AnimationClip获取关键帧信息

1，关键帧数据都保存在AnimationCurve上，所以首先要获取到这个

public static AnimationCurve GetAnimCurve(AnimationClip clip, string path, string propName)
{
    EditorCurveBinding[] bindings = AnimationUtility.GetCurveBindings(clip);
    foreach (var b in bindings)
    {
        if (b.path == path)
        {
            //Debug.Log($"path:{b.path}, propName:{b.propertyName}, discrete:{b.isDiscreteCurve}, pptr:{b.isPPtrCurve}");
            if (b.propertyName == propName)
            {
                var result = AnimationUtility.GetEditorCurve(clip, b);
                return result;
            }
        }
    }
    return null;
}

path和propName

2, 关键帧数据

public static void PrintCurve(AnimationCurve curve)
{
    Debug.Log($"preWrap:{curve.preWrapMode}, postWrap:{curve.postWrapMode}, kfCnt:{curve.length}");

    for (var i = 0; i < curve.keys.Length; ++i)
    {
        var kf = curve.keys[i];
        Debug.Log($"keyFrame:{i}, t:{kf.time}, v:{kf.value}, mode:{kf.weightedMode}, in:{kf.inTangent}, inW:{kf.inWeight}, out:{kf.outTangent}, outW:{kf.outWeight}");
    }
}
