Why is there no method like
Object3D[] getChildren()but there is
Object3D[] getParents()
I have a group of objects (From another example, it is a car and its 4 wheels). I want them all to move together, so I add them as children to another object, which is a collision mesh. And, now I would like to pass the reference to the outer object around, and change all the children simultaneously. For instance, I want to change visibility, or remove them from the world.
All I can think of doing is extend the Object3D class, override the addChild() function to also add the child to a list. Then add a getChildren() function that just returns that list as an array and use this in my own functions.
I just don't understand why there is no getChildren() function?

Because there's no cyclic reference. A child knows its parent(s). A parent has no idea about its child(s). If you need that, you can extend Object3D and add it yourself.

Thank you,
I will do just that
