Group or State getChildren()

Forum › Kiwi.js Game Engine › Group or State getChildren()

    So this might be more of a general typescript question but anyway I have a Kiwi.Group of objects and which are a custom class that derives from a Kiwi.GameObjects.Sprite.

    So the question is if I want to iterate over them I would use something like the following code

    var children: Kiwi.IChild[] = this.getAllChildren();
    for (var obj in children )
    {
    obj.CustomClassFunction();
    }

    Now how do I cast from an IChild to my own custom type? I don’t really want to keep a separate list of objects.

    Thanks in advance

    One way is before calling the CustomClassFunction you can tell typescript to “treat” obj as an instance of your CustomClass.


    var children: Kiwi.IChild[] = this.getAllChildren();
    for( var obj in children )
    {
    (obj).CustomClassFunction();
    }

    Another can be to change the type of your list to any. You may not have code completion if you do it that way though.


    var children: any = this.getAllChildren();
    for( var obj in children )
    {
    obj.CustomClassFunction();
    }

    Hope that helps!
