From what I can tell, WADE doesn't have a built-in way to create container objects, i.e. to parent one SceneObject to another.
For example, if I wanted to essentially group a collection of SceneObjects, where when I move the parent, all the child SceneObjects move as well, relative to their given offset.
In this sense, this would be similar to how SceneObjects already are able to have multiple Sprite components which follow the SceneObject. Except, instead of (or in addition to) Sprites, you could use SceneObjects as children of the SceneObject.
Does this make sense? Is there already some kind of feature like this that I am missing?
