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}");}
}
