problem in hierarchy

[johanesnw]

hi, I'm new to NGUI. I've just bought NGUI 8hours ago (and 1month exp in unity  )
I want to make UI for weapon shop. It's a vertical scrollview on left side, and the weapon preview on right side.
So, for practice I want to clone example7 but make it vertical.
It goes well when I use bunch of sprites only. then I want to group them in an object.

But I got trouble here... its example7's hierarchy

the "item0"... that's just an empty "trigger" GameObject right? or not?

I tried to create GameObject (isTrigger), and highlight it. then from NGUI > create > anything (sprite/tex/label) it won't fit the gameObject I created.
Its like the created sprite fills the entire world, almost 10x panel size (even it's just a 32x32).
below is a screenshot. The white box is a scrollview thats filled with a GIANT sprite that I create inside GameObject.

and you could see the little Xbox "A" sprite in game window. That I create outside gameObject (highlighting nothing, then NGUI>Create), and then drag it to gameObject.

It's been 4 hours since I got this trouble and looking for solutions. but maybe i'll just ask here 

and like I said I just know NGUI last night. so don't be so rude X)

Are you creating the sprite inside the hierarchy? Check your inspector what the size of the sprite actually is - likely you've created them at the root level (outside the UIRoot) which means 32x32 is gigantic, because UIRoot scales all its children by 1/screen.height to achieve the virtual pixels that you use in localPosition.

So, check the localScale in the inspector - everything should be 1,1,1 all the way up to the UIRoot which will be some tiny number.

aha... got it now. If I create an empty game object it will always be a root. then I drag that empty object to UI Root, and didn't notice that the scale is 360x360x360.
just clicking the "S" solves everything. thanks Nicki 
I'm glad this error occurs in my 1st day. so that I won't get into this later
