Hi,
I am new to iOS development and especially to touch control. I would like to make simple ​​flicking marbles game.
I looked at the documentation on TouchPhase, but I’m not sure how to do it.
Thanks for any advice.

Here’s some touch phase code I used. I only had to determine if the swipe went left, right, up, or down. You’ll have to sort out the precise direction of the swipe, but this should give you a head start.

        foreach (Touch touch in Input.touches)
        {
            if (touch.phase == TouchPhase.Began)
            {
                if (_paused == false)
                {
                    downpoint = Input.mousePosition;
                }
            }

            if (touch.phase == TouchPhase.Ended)
            {
                if (_paused == false)
                {
                    uppoint = Input.mousePosition;
                }
            }
        }
