NGUI 3 Support / Wrong position for child objects

« on: June 30, 2016, 02:06:43 PM »

Guys a Have a question about child components position.

My widget structure is like:

1. - UI Sprite
2.     - Button
3.         - Label
4.  
5.  

Every time, when I try to create a dynamic button inside the sprite, the button "spawn" in the middle of the sprite. Why?
Why the button don't go for the position X = 0 and Y = 0 ?

Here is how I create my button:

1. private void CreateButtonUI(GameObject parent, string name, int width, int height, string label, string atlas = "Atlas/ui")
2.     {
3.         GameObject main = NGUITools.AddChild(parent);
4.         main.name = name;
5.  
6.         // Attach sprite to receive atlas
7.         UISprite background = main.AddComponent<UISprite>();
8.         background.height = height;
9.         background.width = width;
10.         background.atlas = Resources.Load<UIAtlas>(atlas);
11.         background.depth = 1;
12.  
13.         // Add collider to the button
14.         BoxCollider bc = main.AddComponent<BoxCollider>();
15.         bc.size = new Vector3(width, height, 0);
16.         bc.isTrigger = true;
17.  
18.         // Attach button component
19.         UIButton bt = main.AddComponent<UIButton>();
20.  
21.         // Set sprite state
22.         bt.tweenTarget = bt.gameObject;
23.         bt.normalSprite = "btn_brown";
24.         bt.hoverSprite = "btn_green";
25.         bt.pressedSprite = "btn_red";
26.         bt.disabledSprite = "btn_gray";
27.  
28.         // Set text label
29.         GameObject btLabel = NGUITools.AddChild(main);
30.         UILabel lb = btLabel.AddComponent<UILabel>();
31.         lb.bitmapFont = Resources.Load<UIFont>("Fonts/calibri");
32.         lb.depth = 1;
33.         lb.width = 142;
34.         lb.height = 28;
35.         lb.text = label;
36.         lb.alignment = NGUIText.Alignment.Center;
37.         lb.fontSize = lb.bitmapFont.defaultSize;
38.         lb.effectStyle = UILabel.Effect.Shadow;
39.         lb.applyGradient = false;
40. }
