Selecting one item from grid

[webik150]

Hi. Well... my menu is almost done! One last thing I need to do. I have grid with items, and I want to be able to select between them. Like there are 4 countries, and when you click on one, it gets yellow overlay. When you click on another, the first loses its overlay, and the another one gets it. Could you please help me with script, or tell me if there's some tutorial somewhere? Thanks.


I know that this text doesn't make much sense, but I really don't know how else to say it...

BroadcastMessage would work great here since each of the buttons are children of the same game object (the grid).  Each button/country would need a script with these functions...

1. public GameObject overlay;
2.  
3. void OnClick()
4. {
5.     transform.parent.BroadcastMessage("Select", false);
6.     Select(true);
7. }
8.  
9. void Select(bool selected)
10. {
11.     if (selected)
12.     {
13.         //turn on overlay
14.         NGUITools.SetActive(overlay, true);
15.     }
16.     else
17.     {
18.         //turn off overlay
19.         NGUITools.SetActive(overlay, false);
20.     }
21. }
22.  

Then just drag and drop the overlay for each of the buttons into the overlay variable slot in the inspector.
Hope this helps

Thanks. I will try that tomorrow, and post what I got.

Don't know, what I did wrong. I have put Button script on the items, then put the script on each of them. It just doesn't do anything. And yeah, I have put the overlay sprites into inspector.

Any suggestions?

You could also just make all the child items a UICheckbox. If they are all under the same parent (your grid) or you give them all the same radioButtonRoot, they will automatically turn on/off the overlay.

You'd probably end up having something like:

UICheckbox
->overlay image
->country image

So that would be a GameObject with a UICheckbox+collider, and then two child sprites. The overlay image should be the 'Check Sprite' of the UICheckbox.

I'll try it. Thanks.
