Tried to do:
thisList.Add(aGameObject.GetComponentsInChildren(Renderer);
but Unity says List is not compatible because it reads it as component, so I needed:
thisList.Add(aGameObject.GetComponentsInChildren(Renderer) as Renderer);
and now, when I try to extend that later in code, like:
for(var kowabunga in thisList){
kowabunga.enabled = true;
}
I get null reference errors. Not sure how to get around this issue.
