Touch Direction and Keep direction

So i created small script which identifies the direction of a touch swipe and keeps that direction till you move to another direction or let go of your finger.Thought of sharing

Code (CSharp):

1.  
2. public float touchThreshold = 0.3f;
3. Direction tocuhDirction;
4. enum Direction
5.     {
6.         right = 1,
7.         left = -1,
8.         noDirction = 0
9.     }
10. void update(){
11. if (Input.touchCount != 0)
12.         {
13.             if (Input.touches[0].phase == TouchPhase.Began)
14.             {
15.                 initialTouch = Input.touches[0];
16.             }
17.             else if (Input.touches[0].phase == TouchPhase.Moved || tocuhDirction != Direction.noDirction)
18.             {
19.                 float deltaX = Input.touches[0].position.x - initialTouch.position.x;
20.                 if (deltaX > touchThreshold || tocuhDirction == Direction.right)
21.                 {
22.                     tocuhDirction = Direction.right;
23.                     //do whatever you want here
24.  
25.                 }
26.                 if (deltaX < -touchThreshold || tocuhDirction == Direction.left)
27.                 {
28.                     tocuhDirction = Direction.left;
29.                     //do whatever you want here
30.                 }
31.             }
32.  
33.         }
34. }

 

CAUTION: If you think you are implementing the Update() method in a Monobehavior, the above script is not implementing that method. Did you just retype all this in?!

 

i just typed it in my bad i just thought this would make it easier to copy paste it to quickly test it
