tk2dButton clicks doesn't work on Unity4.2 beta

[nemoryoliver]

I can confirm this is the line that doesn't get called:

Code: [Select]

            if (Input.GetMouseButtonDown(0))
            {
                Debug.Log("Casting Ray");

                Ray ray = viewCamera.ScreenPointToRay(Input.mousePosition);
                RaycastHit hitInfo;

                if (collider.Raycast(ray, out hitInfo, 1.0e8f))
                {
                    if (!Physics.Raycast(ray, hitInfo.distance - 0.01f))
                        StartCoroutine(coHandleButtonPress(-1));
                }
            }

Lucky I found how to fix the issue.

tk2dButton.cs

Really? Thats terrible
That value is the length of the ray. Can you please try it with Mathf.Infinity instead of 100? (Don't have the beta installed due to checking another bug elsewhere...)

[nemoryoliver]

I also have to move out to the block that if statement. because the Else statement is not entered. This problem is only in the Editor though. no problem with the device.

Here's the Unity4.2 b2   removed link

I am not sure if you will be able to download it.

[nemoryoliver]

Mathf.Infinity works.

[unikronsoftware]

Hi I removed that link you shared - its private
Yes, I've got access to it - just haven't had the time to install and test in it.

Glad math.infinity works though.

[nemoryoliver]

Sorry for posting the link. And it's nice you got 4.2. Let me know when you got the same issue and if you got a different way to fix. thanks.

[unikronsoftware]

No, that is probably the correct thing to do - though it looks like they have introduced a bug. Mathf.Infinity > 1.0e8, so I dont know why its not working. I think there were a few more people complaining about broken physics in the beta forum...

[nemoryoliver]

Oh. But there's a bug to the new Editor right? Anyway it works now. Thanks man,

Hi!

I just bought 2D Toolkit, and updated to Unity 4.2, and tk2dButton doesn't work

In the editor when clicking Play on the "6 - button and 3d sprites" demo, if I click any button it doesn't work.
As I have seen in the code, my clicks go through here:

Code: [Select]

#if !UNITY_FLASH
if (Input.multiTouchEnabled)
{
for (int i = 0; i < Input.touchCount; ++i)
{
Debug.Log("bucle "+i);
But never gets to the Log command, so there's multiTouch, but no touchCount when clicked.
I'm using Windows 7, and as I'm aware of... I don't have any multi touch device.

Edit:
I set

#if !UNITY_FLASH && false

and now it works perfectly.
Strange, isn't it? :/

[unikronsoftware]

What build platform have you got set?

[ahtram]

Same problem here.
I set my project in Android platform and using Unity under a windows 8 machine.

What build platform have you got set?

I had MacOSX and changed to Windows and x64, but the button still didn't work.

After a bit of investigation, it looks like Unity has decided to change how Input.multiTouchEnabled works.
It now returns true on everything I've tried it on, even my macbook which clearly doesn't have a multitouch display.

Using this makes it work:

Code: [Select]

bool resolvedHit = false;

#if !UNITY_FLASH
if (Input.multiTouchEnabled)
{
for (int i = 0; i < Input.touchCount; ++i)
{
Touch touch = Input.GetTouch(i);
if (touch.phase != TouchPhase.Began) continue;
            Ray ray = viewCamera.ScreenPointToRay(touch.position);
            RaycastHit hitInfo;
            if (collider.Raycast(ray, out hitInfo, 1.0e8f))
            {
if (!Physics.Raycast(ray, hitInfo.distance - 0.01f))
{
StartCoroutine(coHandleButtonPress(touch.fingerId));
resolvedHit = true;
break; // only one finger on a buton, please.
}
            }            
}
}
#endif

if (!resolvedHit)
{
if (Input.GetMouseButtonDown(0))
        {
            Ray ray = viewCamera.ScreenPointToRay(Input.mousePosition);
            RaycastHit hitInfo;
            if (collider.Raycast(ray, out hitInfo, 1.0e8f))
            {
if (!Physics.Raycast(ray, hitInfo.distance - 0.01f))
StartCoroutine(coHandleButtonPress(-1));
            }
        }
}

In any case, I strongly recommend using the tk2dUIButton - its far more efficient to use and much more customizable, and this thing has been more or less deprecated (reminds me I need to replace them in the demos). Check out the tk2dUI demo.
