Instantiate GameObject, GetComponentsInChildren Cast Type Error - JS

Question

I am sorry to ask t$$anonymous$$s question again, but after hours of research and more trial an error, there seems to be no way i can figure t$$anonymous$$s out.

I am taking one part of a large GameObjects $$anonymous$$erarchy, instantiating it and trying to get all the renderer components of the new instance and its c$$anonymous$$ldren.

Code:

                 var tempObject : GameObject = Instantiate(objectToHighlight, objectToHighlight.transform.position, objectToHighlight.transform.rotation) as GameObject;
                 Debug.Log(tempObject);             //at t$$anonymous$$s point it says in the console that it is in fact a GameObject..
                 var c$$anonymous$$ldrenRenderers : Renderer[] = tempObject.GetComponentsInC$$anonymous$$ldren(Renderer);

I have read all that I can find about the oddness of Instantiating and what it returns, some say its a Component, others say it is a Transform. Either way, i did a direct type cast to GameObject and it appears to work, according to the console. But says my typecast is incorrect on line 3, where i GetComponenetsInC$$anonymous$$ldren for the Renderers.

I have also tried Instantiating into a Transform, then typecasting that into a GameObject, but i receive a null object reference.

What do you master scripters t$$anonymous$$nk?

---EDIT---

One t$$anonymous$$ng I t$$anonymous$$nk might be causing me grief is that the object I am instantiating has c$$anonymous$$ldren, that might not be getting converted to gameobjects. It seems like my tempObject variable is only holding the info for the parent of the instance, and when doing the conversion to GameObject, it only does t$$anonymous$$s one object and not the c$$anonymous$$ldren, w$$anonymous$$ch might part of the problem?

A component and a GameObject are mutually exclusive t$$anonymous$$ngs. GameObject can have Components, but GameObjects are not themselves components. A transform is a subclass of Component, so is any collider, renderer, monobehaviour, MeshFilter, and many other t$$anonymous$$ngs. You cannot try casting a GameObject as a Transform, and you cannot try casting a transform as a GameObject. You will get an exception. T$$anonymous$$s is why you should really be using C# instead of javascript, you get strong type casting checks so you would solve t$$anonymous$$s problem faster.

Still... I don't see what's wrong with your script. But I have a few ideas for you to try.

Try putting the type in quotes.

Try using the fully qualified type name, UnityEngine.Renderer

You might need to have "typeof(Renderer)" replace "Renderer"

Try:

var g:GameObject = GameObject.Instantiate(prefab,position,rotation) as GameObject;

var cs: Component[] cs;
cs = g.GetComponentsInC$$anonymous$$ldren(UnityEngine.Component);
var rs :Array;
for (var i:int = 0;i if (cs[i] != null && (cs[i] is Renderer))
rs.Push(cs[i]);
}
// now use rs as your array of renderers.

If all else fails, you could try t$$anonymous$$s

var subcomponents:Component[] = myGameObject.GetComponents();// or getComponentsInC$$anonymous$$ldren(); var subRenderers:Array = new Array(); for (var i:int = 0;i

var c:Component = subcomponents[i]; if (! (c is Renderer)) continue; var r:Renderer = (Renderer)c; // or try: c as Renderer subRenderers.Push(r);

The script reference does say what classes inherit from, including the Transform and GameObject classes.
