UICamera.touchCount BUG? KeyNotFoundException

[danfoo]

Hi,

Calling UICamera.touchCount

1. if(activeTouches != UICamera.touchCount)

results in an error on line 386 in UICamera.cs:
KeyNotFoundException: The given key was not present in the dictionary.

1.         if (mTouches[i].pressed != null)

Please advise? Thanks!

I should probably add that this happens when only using touches in the editor (via Unityremote). After disabling mouse input in UICamera, the error started to occur.

Unity remote is crap; don't rely on it.

Not really a constructive reply. I see you are a moderator. Does that mean I should consider your reply as one backed by Tasharen?

Unityremote is quite handy during UI testing, at least it was with our previous UI system. How else would you suggest we do fine-tuning? Build the project each time we tweak a value? You can't be serious.

Unity remote sends both mouse and touch events from a single action, which messes with NGUI, which is why using it is not advised.

Change this:

1. for (int i = 0; i < mTouches.Count; ++i)
2.                                 if (mTouches[i].pressed != null)
3.                                         ++count;

to this:

1. foreach (KeyValuePair<int, MouseOrTouch> t in mTouches)
2.                 if (t.Value.pressed != null)
3.                     ++count;

I was having the same issue running my game under iOS and the XCode debugger, however this patch fixed it for me...were you planning on including it in an upcoming release?

It's already in the Pro version, so yup.

No, my answers are not official support answers by Tasharen, I'm just helping out in here.

Unity remote is utterly useless in my opinion, but your mileage may vary.

Thanks. Perhaps it's time to upgrade to pro...
