Title: Offset Child Inside UIGrid
Post by: Ace on November 23, 2014, 12:49:14 PM

Greetings!

I am trying to fix the position of objects inside a UIGrid.

Right now I have a deck object in top corner. When I add cards to it, I want to offset those cards by width/2 and height/2 so they are top left added to the list (instead of center added as they are currently):

However when I offset the position of the children when I add them, I think those changes get overriden by having to call Reposition() (and nothing appears if I don't call that).

Here is my code:

1. //Puts cards at the top of the screen
2.         public static void dealFirstHand()
3.         {
4.                 deck = GameObject.FindGameObjectWithTag("deck");
5.                 for(int i =0;i<6;i++)
6.                 {
7.                         GameObject card =  NGUITools.AddChild(deck,Resources.Load("Prefabs/UI/CardSlot") as GameObject);
8.                         assignRandomCard(card.GetComponent<UI_Controller_CardSlot>().cardArt);
9.                         UIPanel display = card.transform.GetComponentInChildren<UIPanel>();
10.                         card.transform.parent = deck.transform;
11.                         card.transform.localScale = new Vector3(1f,1f,1f);
12.                         card.transform.position = new Vector3(display.width/2,display.height/2,0);
13.                         playerCards.Add(card.GetComponent<UI_Controller_CardSlot>().cardArt,false);
14.                         card.GetComponent<UI_Controller_CardSlot>().cardArt.activate();
15.                 }
16.                
17.                 deck.GetComponent<UIGrid>().Reposition();
18.         }
19.  

Can you advise how I can properly get it so cards are added so that my offset values apply? I verified card.transform.position = new Vector3(display.width/2,display.height/2,0); gives the correct values so can you tell me where I can put this to get it to register? Do I need to loop through the cards again and reposition them manually? (That seems very inefficient)

The object being added is center pivoted, and I want that to stay center pivtoted. I just want the children added to be offset by width/2 and height/2.

Thanks

Grid simply changes the position of transforms underneath it. If you want there to be an offset, then do just that. Instead of just having your items structured like this:

Sprite (centered pivot)
- Another sprite
- Label, etc

You would instead have something like this:

Widget (top left pivot likely would be best -- can also be a simple game object)
- Sprite
- Another sprite
- Label, etc

Was hoping to do it programatically but Ill make that change.

Thanks
