Question Touch Input system not working on my project

Hello i'm trying to make my own tetris game on my android phone. I am trying to do,
1- Touch and release screen making rotation,
2- Touching and swiping for down, left and right not making any rotation.

Here is my code, any suggestion would be great, thank you so much!

Code (CSharp):

1.     private Vector2 touchStartPos;
2.     private bool isRotating = false;
3.     private float swipeThreshold = 75.0f;
4.  
5.     private void Update()
6.     {
7.         this.board.Clear(this);
8.  
9.         this.lockTime += Time.deltaTime;
10.  
11.         if (Input.touchCount > 0)
12.         {
13.             Touch touch = Input.GetTouch(0);
14.  
15.             if (touch.phase == TouchPhase.Began)
16.             {
17.                 touchStartPos = touch.position;
18.                 isRotating = false;
19.             }
20.             else if (touch.phase == TouchPhase.Moved)
21.             {
22.                 if (!isRotating)
23.                 {
24.                     float swipeDistance = touch.position.x - touchStartPos.x;
25.                     float verticalDistance = touch.position.y - touchStartPos.y;
26.  
27.                     if (Mathf.Abs(swipeDistance) > Mathf.Abs(verticalDistance))
28.                     {
29.                         if (Mathf.Abs(swipeDistance) > swipeThreshold)
30.                         {
31.                             if (swipeDistance > 0)
32.                             {
33.                                 Debug.Log("Movement for right.");
34.                                 Move(Vector2Int.right);
35.                             }
36.                             else
37.                             {
38.                                 Debug.Log("Movement for left.");
39.                                 Move(Vector2Int.left);
40.                             }
41.                         }
42.                     }
43.                     else if (verticalDistance < -swipeThreshold)
44.                     {
45.                         Debug.Log("Movement for down.");
46.                         Move(Vector2Int.down);                      
47.                     }
48.                 }
49.             }
50.             else if (touch.phase == TouchPhase.Ended)
51.             {
52.                 if (!isRotating)
53.                 {
54.                     isRotating = true;
55.                     Debug.Log("Touch detected, processing.");
56.                    
57.                     Rotate(1);
58.                 }
59.             }
60.         }
61.     }

My all code is attachment.

 

There is more important problem than input system, which is cognitive complexity of your method (that means there is a lot of nested if else), it makes harder to read and debug your code. I suggest you to fix that first with some techniques (like early return, splitting to local methods, state machine pattern). Then I believe you will find solution yourself. Also there is a very useful plugin if you use Rider https://plugins.jetbrains.com/plugin/12024-cognitivecomplexity/

 

Thank you for suggesting but i actually can't find the solution by myself so i still need a help. If i can find the true code i can do the things you said. If you know anything about my solution please share with me. Thank you!

I check this links too but can't find.

Funny. I came here for the same thing... and appears... we are working on the same project.

 

I don't know if you figured it out, but I got this:

Code (CSharp):

1. board.Clear(this);
2.  
3.         if (Input.touchCount > 0)
4.         {
5.             theTouch = Input.GetTouch(0);
6.  
7.             if (theTouch.phase == TouchPhase.Began)
8.             {
9.                 touchStartPosition = theTouch.position;
10.             }
11.             else if (theTouch.phase == TouchPhase.Moved || theTouch.phase == TouchPhase.Ended)
12.             {
13.                 touchEndPosition = theTouch.position;
14.  
15.                 float x = touchEndPosition.x - touchStartPosition.x;
16.                 float y = touchEndPosition.y - touchStartPosition.y;
17.  
18.                 if (Mathf.Abs(x) == 0 && Mathf.Abs(y) == 0)
19.                 {
20.                     direction = "Tapped";
21.                 }
22.                 else if (Mathf.Abs(x) > Mathf.Abs(y))
23.                 {
24.                     direction = x > 0 ? "Right" : "Left";
25.                     if(direction == "Right")
26.                     {
27.                         Move(Vector2Int.right);
28.                     } else if(direction == "Left")
29.                     {
30.                         Move(Vector2Int.left);
31.                     }
32.                 }
33.                 else
34.                 {
35.                     direction = y > 0 ? "Up" : "Down";
36.                     if(direction == "Up")
37.                     {
38.                         // Rotate
39.                         Rotate(1);
40.                     } else if(direction == "Down")
41.                     {
42.                         Move(Vector2Int.down);
43.                     }
44.                 }
45.             }
46.         }
47.  
48.         // End Mobile Input
49.  
50.         board.Set(this);

It's working as the swipes are moving the pieces, the only problem is they're moving way too fast. Still trying to figure that out.
