如何动态给文件夹中的预制件添加BoxCollider

UnityEngine.Object[] selObjs = Selection.GetFiltered(typeof(UnityEngine.Object), SelectionMode.DeepAssets);

for (int i = 0; i < selObjs.Length; i++)
{
　　UnityEngine.Object selObj = selObjs[i];
　　string path = AssetDatabase.GetAssetPath(selObj);
　　if(path.EndsWith(".prefab"))
　　{
　　　　var targetComponent = AssetDatabase.LoadAssetAtPath<GameObject>(path);
　　　　if (targetComponent.GetComponent<BoxCollider>())
　　　　　　return;
　　　　BoxCollider collider = targetComponent.AddComponent<BoxCollider>();
　　　　SkinnedMeshRenderer meshReader = targetComponent.GetComponentInChildren<SkinnedMeshRenderer>();
　　　　collider.size = new Vector3(meshReader.bounds.extents.x * 2, meshReader.bounds.extents.z * 2, meshReader.bounds.extents.z * 2);
　　　　collider.center = new Vector3(meshReader.bounds.center.x , meshReader.bounds.center.y, meshReader.bounds.center.z );
　　}
}

注：通过获取meshReader.bounds 的数据来生成BoxCollider 的大小和位置
