Instantiated Button/Sprite Issue

[stevej]

See video below.

I have a button called "ChestEntry" that I instantiate into a UIGrid to show individual items within a "treasure chest".

Basically, I iterate through a list of items that should be in the chest and execute something like:

1. GameObject newChestEntryGo = Instantiate(chestEntry, Vector3.zero, Quaternion.identity) as GameObject;
2. newChestEntryGo.GetComponent<UIButton>().normalSprite = thisItem;
3. newChestEntryGo.transform.parent = gridChestContentGo.transform;
4.  

At the end, I tell the UIGrid to reposition and then it's all displayed on screen.

The issue seems to be that the sprite applied in code for each item doesn't seem to "stick" and it constantly changes back to the "empty" sprite that's assigned to the source GameObject (ChestEntry) that's copied for all the others. Hopefully the video makes the issue a little clearer than I can describe it

Any thoughts on whether or not this is something wrong with my approach, or is it an NGUI bug?

Thanks!

I'm not sure if this is the right solution, but ArenMook has clearly stated that we shouldn't use instantiate.

Try using the AddChild method, might work better

Oooo! Hadn't seen that before. Have switched to:

1. GameObject newChestEntryGo = NGUITools.AddChild(gridChestContentGo, chestEntry);
2. newChestEntryGo.GetComponent<UIButton>().normalSprite = thisItem;
3.  

Exact same result/problem - but thanks for the info. Didn't realise there was a nicer way.

Got lucky with a search and found the following:

Which fixes the problem for me.

Hoping that will be fixed in a future version.

That code is already there. Sounds like you didn't update your NGUI.
