Hey, I have this scene:

With the transform handle set to ‘center’. ‘GameObject’ is just an empty gameobject. How can I get the position of that center tool handle?

You can’t. At least Unity doesn’t calculate that for you. In the editor it’s a feature that is built-into the editor.

The best approach would be to iterate over all Renderer in all child objects, gather the worldspace bounds values and combine them with [Bounds.Encapsulate][1].

Vector3 GetCenter()
{
    var rends = GetComponentsInChildren<Renderer>();
    if (rends.Length == 0)
        return transform.position;
    var b = rends[0].bounds;
    for(int i = 1; i < rends.Length; i++)
    {
        b = b.Encapsulate(rends*.bounds);*

}
return b.center;
}
