I'm making a game similar to Wordscapes, I've been trying to figure out a way to select the letters by swiping. I'm new to mobile input so I'm not sure what to do next. Here is my input script that I found on the internet and modified a bit to my liking. It works as expected, but only detects a single swipe motion. How do I fire an onclick event when the user swipes over a button? If possible, Id like to send that information to the OnSwipe delegate (since I use this from other scripts to handle on swipe events)
I figured raycasting from the camera would be the best option. Maybe someone could help me modify this code since I don't fully understand how to go about it all. Thanks!
// Class used for detecting touch input (Swipe Exclusive)
public class TouchInput: MonoBehaviour {
public static event Action<SwipeData> OnSwipe = delegate { };
private Vector2 startPosition;
private Vector2 endPosition;
private float moveDistanceY = 0f;
private float moveDistanceX = 0f;
private SwipeDirection sDirection = new SwipeDirection();
/// <summary>
/// Update is called once per frame
/// </summary>
private void Update() {
foreach (Touch touch in Input.touches) {
if (touch.phase == TouchPhase.Began) {
endPosition = touch.position;
startPosition = touch.position;
} else if (touch.phase == TouchPhase.Ended) {
startPosition = touch.position;
DetectSwipe();
}
}
}
/// <summary>
/// Handles the detection of swipes
/// </summary>
private void DetectSwipe() {
moveDistanceY = Mathf.Abs(startPosition.y - endPosition.y);
moveDistanceX = Mathf.Abs(startPosition.x - endPosition.x);
if (moveDistanceX > 20f || moveDistanceY > 20f) {
if (moveDistanceY > moveDistanceX) {
sDirection = startPosition.y - endPosition.y > 0 ? SwipeDirection.Up : SwipeDirection.Down;
SendSwipe(sDirection);
} else {
sDirection = startPosition.x - endPosition.x > 0 ? SwipeDirection.Right : SwipeDirection.Left;
SendSwipe(sDirection);
}
endPosition = startPosition;
}
}
/// <summary>
/// Sends data about the swipe to the "OnSwipe" Delegate
/// </summary>
private void SendSwipe(SwipeDirection dir) {
SwipeData swipeData = new SwipeData() {
Direction = dir,
StartPosition = startPosition,
EndPosition = endPosition
};
OnSwipe(swipeData);
}
