MAC Input Issues

[rterranova]

On MAC web player the input field does not register the delete key press or the tab key press.

I have seen a couple of post addressing this problem, and you mentioned that this is a Unity 4.x issue, but I cannot find anything on the Unity forms saying they are seeing issues.  Do you know where I can find a mention of this issue?

I don't have a link on hand. It is indeed a Unity issue, and if you want to be sure -- submit another bug, but don't use the word NGUI in it. Instead create a very simple stand-alone project (without NGUI) that simply listens to Input.inputString. Backspace will show up as '\b' everywhere except Mac web player.

Hello,

In several posts you say this is a Unity bug, however i tested this, on all platforms I receive the backspace just fine. So is it possible this is a bug in NGUI after all?

1. string input = Input.inputString;
2. if(Input.GetKey(KeyCode.Backspace))
3.         Debug.LogError ("Backspace pressed");
4. foreach(char c in input)
5. Debug.LogError ("Received: " + (int)c);
6.  

If I press backspace, I get "Backspace pressed" 4 times and once "Received: 8", both on mac and windows.

So the backspace does register, however, not in a NGUI input...

I'm a missing somthing perhaps?

This bug is in the mac web player. Unity Editor works just fine.

Yes I know, the results are from the MAC webplayer and the Win Webplayer...

From which version of Unity?

[grrava]

Unity version is pro 4.1.3, both editor and webplayers.

I found some other posts in this forum about UIInput, and found a discussion about the Input.imeCompositionMode. In the test code I provided earlier you see that I do not change the input mode, so I changed the test class:

1. public class InputTest : MonoBehaviour {
2.        
3.         void Start() {
4.                 Input.imeCompositionMode = IMECompositionMode.On;
5.         }
6.  
7.         void Update () {
8.                 string input = Input.inputString;
9.                 if(Input.GetKey(KeyCode.Delete))
10.                         Debug.LogError ("Delete pressed");
11.                 if(Input.GetKey(KeyCode.Backspace))
12.                         Debug.LogError ("Backspace pressed");
13.                 if(Input.GetKey(KeyCode.Tab))
14.                         Debug.LogError ("Tab pressed");
15.                 foreach(char c in input)
16.                         Debug.LogError ("Received: " + (int)c);
17.         }
18. }
19.  

The results are these:

• windows, firefox: Input.GetKey does receive events (however, we don't want that since the IME mode is on??) Backspace has value 8, Tab has none, Delete has none
• mountain lion osx, chrome & firefox: Input.GetKey does not receive events (which is good), Backspace has no value, Tab has 9, Delete has none.

So, buggy Unity after all, I just missed the imeComposition thingy. I'll try to fix this and if I find a working solution I'll post it here.

Sorry for the confusion and thanks for the help.

We're seeing this issue too.  I'm not sure if this has been fixed in Unity yet (as of 4.2 I've not seen it in the release notes) but did you find a work around?
