Root를 제외한 경로반환

v1 ~ v3

가령 Root/armature/Hips는 /armature/Hips가 된다

string ArmaturePath(Transform bone)
{
    var rootName = bone.transform.root.name;
    var hierarchyPath = bone.transform.GetHierarchyPath();
    return hierarchyPath.Substring(rootName.Length, hierarchyPath.Length - rootName.Length);
}

 

 

Root를 제외한 경로반환 v2 (상대경로)

인자를 하나 더 받고 안정성을 높였다

static string RelativePath(Transform target, Transform root = null)

v3

{
    var rootName = "";
    var hierarchyPath = "";


    if (root != null)
    {
        try

        return null;
    }

    try
    {
        return hierarchyPath.Substring(startIndex, hierarchyPath.Length - startIndex);
    }
    catch (System.Exception ex)
    {
        Debug.LogError(ex);
        Debug.LogError($"{hierarchyPath} - {rootName}");
        throw;
    }
}

 

 

v4

경우에 따라 앞에 슬래시는 없애도 된다

var relativePath = "/"+Path.GetRelativePath(rootpath, path);

 

 

 

 

 

 

하이어라키 경로 반환

var path = SearchUtils.GetHierarchyPath(gameObject, false);

 

 

 

패스 병합

Replace 붙은 이유는 유니티는 '/'를 쓰는데 일부 로직에서 '\'를 인식 못하기 때문

var path = Path.Join(parentPath, childPath).Replace("\\", "/");
