UICamera's touch API

[ryan]

I'm trying to integrate a project's input processing with the work NGUI's already doing in UICamera.  In the past, I've had a separate class that looks at Unity's Input.touches and just does a raycast to see if it's a UI touch and ignores it, but this seems wasteful since I should just be able to ask UICamera.  I see onCustomInput as a handy place to hook in after UICamera has done its work, but getting access to its MouseOrTouch instances is a little wonky.

There's no public access to the mMouse, so if I want to know if a mouse click was on a UI object, I have to figure it out myself.  This is in spite of the fact that mMouse is included in the calculations for touchCount and dragCount.  I do have access to the touches through GetTouch, but this potentially dirties the list of touches if I ask for a touch ID that has been removed.  Also, if I want to account for controller input, onCustomInput is called between mouse/touch processing and controller processing, so that could be problematic.

Of course I can make changes, but for now I'm trying to avoid any custom changes to NGUI to make updating easier.  Am I over-thinking/over-complicating things?  Is there an easier way to go about deciding whether or not to process a touch?

GetTouch(-1) gives you the left mouse button. I assume this is what you're missing?

I thought that was true at one point, and I see that ProcessMouse uses negative touch IDs, but it also goes directly to mMouse instead of calling GetTouch.  I don't see where the mouse inputs would ever end up in mTouches, and GetTouch never looks at mMouse.

Ah yes true. The curse of local modifications and having too many projects... Well, just add this:

1.         /// <summary>
2.         /// Get the details of the specified mouse button.
3.         /// </summary>
4.  
5.         static public MouseOrTouch GetMouse (int button) { return mMouse[button]; }

I've also added it locally so you will see it in a future update.
