[C#] Creating list on runtime while check if it returns null

Unity Engine

Hi guys,

im trying to create a list of all the childs, and while it is created i want to check if the list turns out to be null.

Take a look please:

void Update () {
        if (GM.gameprogress == activeAt) {
            active = true;
            int i = 0;

            List<GameObject> children = new List<GameObject>();
            foreach (Transform child in transform) {
                if (child.gameObject.layer == 27) {
                    child.gameObject.SetActive (true);

                    children.Add(child.gameObject);

                } else {
                    child.gameObject.SetActive (false);
                }


            }
//THIS PART DOES NOT WORK
            if(children == null){
                active = false;
                GM.gameprogress += 1;
            }
//
        }
    }

So in my Game I have a gameobject with lets say 2 childs, as soon as those childs are destroyed the list should return null to set the gameprogress +1 stuff.

Can anyone enlighten me?

THank you Guys!

just because you dont have children doesnt mean your existence is void. you should check the children count children.count <= 0. or check if all children are null.
