Using UI without camera

[pushxtonotdie]

I'd like to use the NGUI framework as items within the scene. In my case there is a tooltip in 3d space that would be clickable. I have created a new UI without a camera by selecting 'none' in the UI panel. I can create and display my UI without issue, but items are not clickable. Is it possible to use NGUI without requiring a camera object at the top of the hierarchy?

After looking around it seems that the interaction of the basic UIButton* scripts all require a UICamera. I have made a quick adapter to more easily use these components without a UI Component:

1.         public void OnMouseEnter(){
2.                 SendMessage("OnHover", true, SendMessageOptions.DontRequireReceiver);
3.         }
4.  
5.         public void OnMouseExit(){
6.                 SendMessage("OnHover", false, SendMessageOptions.DontRequireReceiver);
7.         }
8.  
9.         public void OnMouseDown()
10.         {
11.                 SendMessage("OnPress", true, SendMessageOptions.DontRequireReceiver);
12.         }
13.  
14.         public void OnMouseUp()
15.         {
16.                 SendMessage("OnPress", false, SendMessageOptions.DontRequireReceiver);
17.         }
18.  

This seems to work if I put it on a button (or I guess similar control).

You need the UICamera component on your game camera, or nothing seen by the game camera will be capable of receiving events.

Just attach a UICamera to your game camera.
