Question by Mypenguinbuddy · Aug 15, 2015 at 05:08 PM · c#touch controlsswipe

C# How do I implement swipe controls into my mobile game?

I'm making an isometric tile-based game where the player moves a set distance tile-by-tile up, down, left, of right. Right now my player is moving with the WASD keys. I want the player to move in the direction that you swipe.

I went online and found this script: var startTime: float; var startPos: Vector2; var couldBeSwipe: boolean; var comfortZone: float; var minSwipeDist: float; var maxSwipeTime: float;

 function Update() {
     if (iPhoneInput.touchCount > 0) {
         var touch = iPhoneInput.touches[0];
        
         switch (touch.phase) {
             case iPhoneTouchPhase.Began:
                 couldBeSwipe = true;
                 startPos = touch.position;
                 startTime = Time.time;
                 break;
            
             case iPhoneTouchPhase.Moved:
                 if (Mathf.Abs(touch.position.y - startPos.y) > comfortZone) {
                     couldBeSwipe = false;
                 }
                 break;
            
             case iPhoneTouchPhase.Stationary:
                 couldBeSwipe = false;
                 break;
            
             case iPhoneTouchPhase.Ended:
                 var swipeTime = Time.time - startTime;
                 var swipeDist = (touch.position - startPos).magnitude;
                
                 if (couldBeSwipe  (swipeTime < maxSwipeTime)  (swipeDist > minSwipeDist)) {
                     // It's a swiiiiiiiiiiiipe!
                     var swipeDirection = Mathf.Sign(touch.position.y - startPos.y);
                    
                     // Do something here in reaction to the swipe.
                 }
                 break;
         }
     }
 }

Here is the script I have right now to make the player move a set distance of 1 for each button press:

 using UnityEngine;
 using System.Collections;
 
 public class PlayerMovement : MonoBehaviour {
 
     Vector3 pos;                                // For movement
     float speed = 2.0f;                           // Speed of movement
     static bool[] moving;
     
     void Start () {
         moving = new bool[5];
         pos = transform.position;          // Take the initial position
         GetComponent<BoxCollider2D>().enabled = false;
     }
     
     void FixedUpdate () {
         if (gameObject.tag == "Player") {
             moving[4] = !(Vector2.Distance(transform.position, pos) < 0.01f);
         }
         else {
             moving[GetComponent<CollectFruit>().ID] = !(Vector2.Distance(transform.position, pos) < 0.01f);
         }
         bool doneMoving = DoneMoving ();
         if (doneMoving) {
             GetComponent<BoxCollider2D>().enabled = true;
         }
         if(Input.GetKey(KeyCode.A) && doneMoving && transform.position.x > -1.9f) {        // Left
             pos += Vector3.left;
         }
         if(Input.GetKey(KeyCode.D) && doneMoving && transform.position.x < 1.9f) {        // Right
             pos += Vector3.right;
         }
         if(Input.GetKey(KeyCode.W) && doneMoving && transform.position.y < 1.9f) {        // Up
             pos += Vector3.up;
         }
         if(Input.GetKey(KeyCode.S) && doneMoving && transform.position.y > -1.9f) {        // Down
             pos += Vector3.down;
         }
         transform.position = Vector3.MoveTowards(transform.position, pos, Time.deltaTime * speed);    // Move there
     }
     public bool DoneMoving() {
         return !moving[0] && !moving[1] && !moving[2] && !moving[3] && !moving[4];
     }
 }

How would I implement the swipe controls into my player movement script?
