Double Tap on iOS different to Android behaviour?

Hi,

today I came up to an issue were I'm not able to get a solution for.
I want to zoom in with a doubletap. Its working just fine on my Android Device, but when I try the exact same code on an iPad, its not working and I dont know why?

I already searched this Forum and the Unify Forum for any clue but with no luck.

Any1 got a similar behaviour and eventually solved this problem?

Here is my code snippet:

Code (csharp):

1. float lastTapTime = -1;
2. float tapTime = -1;
3. float doubleTapThreshold = 0.5f;
4. bool doubleTap = false;
5.  
6. void FixedUpdate()
7. {
8.    if (Input.touchCount > 0  Input.GetTouch(0).phase == TouchPhase.Began  Input.GetTouch(0).phase != TouchPhase.Moved)
9.    {
10.        lastTapTime = tapTime;
11.        tapTime = Time.time;
12.                
13.        if (tapTime - lastTapTime <= doubleTapThreshold)
14.           doubleTap = true;
15.        else
16.           doubleTap = false;
17.    }
18.  
19.    if (doubleTap)
20.    {
21.        if (scale == new Vector2(1.0f, 1.0f))
22.           scale = new Vector2(2.0f, 2.0f);
23.         else
24.         {
25.             scale = new Vector2(1.0f, 1.0f);
26.             matrixTransform = new Vector3(1, 1, 1);
27.         }
28.          doubleTap = false;
29.    }
30. }

Thanks for any help.

You can always use .tapCount instead of implementing it yourself.

Hi Eric.

thanks for the quick answer, but I don't exactly know what you mean. I already tried my if statement with Input.GetTouch(0).tapCount, but I think I miss something.

.tapCount returns the number of taps for that touch. If it's 2, then it's a double-tap. So you don't have to program your own logic, the OS already does this.

Thanks alot for pointing me in the right direction Eric.
Never tought it was that easy. :-D
Now its working just fine.

Thanks again.
