detect Swipe in four directions (android)

Hello
I need to java script code that can detect four directions (up, down , right , left) swipe on screen and debug once when that is happen.
I write some codes with delta position but never couldn’t have result.
thanks

Why don´t you check

float deltaX = deltaPosition.x;
float deltaY = deltaPosition.y;
float biggerDelta = (deltaX > deltaY) ? deltaX : deltaY;
int direction = Mathf.Sign (biggerDelta);

With that info you should be able to get it. At least that´s how I do it.

Edit: new script, same idea, it might need some tweak but I don´t see why it shoudn´t work.

using System.Collections;

public class MiniGestureRecognizer : MonoBehaviour {

	public enum SwipeDirection{
		Up,
		Down,
		Right,
		Left
	}

	public static event Action<SwipeDirection> Swipe;
	private bool swiping = false;
	private bool eventSent = false;
	private Vector2 lastPosition;
	
	void Update () {
		if (Input.touchCount == 0) 
			return;

		if (Input.GetTouch(0).deltaPosition.sqrMagnitude != 0){
			if (swiping == false){
				swiping = true;
				lastPosition = Input.GetTouch(0).position;
				return;
			}
			else{
				if (!eventSent) {
					if (Swipe != null) {
						Vector2 direction = Input.GetTouch(0).position - lastPosition;

						if (Mathf.Abs(direction.x) > Mathf.Abs(direction.y)){
							if (direction.x > 0) 
								Swipe(SwipeDirection.Right);
							else
								Swipe(SwipeDirection.Left);
						}
						else{
							if (direction.y > 0)
								Swipe(SwipeDirection.Up);
							else
								Swipe(SwipeDirection.Down);
						}

						eventSent = true;
					}
				}
			}
		}
		else{
			swiping = false;
			eventSent = false;
		}
	}
}

I am sorry about the amount of ifs, I did this quite fast…

This works to me: http://pfonseca.com/swipe-detection-on-unity/

using UnityEngine;
using System.Collections;

public class SwipeDetector : MonoBehaviour 
{
	
	public float minSwipeDistY;

	public float minSwipeDistX;
		
	private Vector2 startPos;

	void Update()
	{
//#if UNITY_ANDROID
		if (Input.touchCount > 0) 
			
		{
			
			Touch touch = Input.touches[0];
			
			
			
			switch (touch.phase) 
				
			{
				
			case TouchPhase.Began:

				startPos = touch.position;
				
				break;
				
				
				
			case TouchPhase.Ended:

					float swipeDistVertical = (new Vector3(0, touch.position.y, 0) - new Vector3(0, startPos.y, 0)).magnitude;

					if (swipeDistVertical > minSwipeDistY) 
						
					{
						
						float swipeValue = Mathf.Sign(touch.position.y - startPos.y);
						
						if (swipeValue > 0)//up swipe

							//Jump ();
						
						else if (swipeValue < 0)//down swipe

							//Shrink ();
						
					}
					
					float swipeDistHorizontal = (new Vector3(touch.position.x,0, 0) - new Vector3(startPos.x, 0, 0)).magnitude;
					
					if (swipeDistHorizontal > minSwipeDistX) 
						
					{
						
						float swipeValue = Mathf.Sign(touch.position.x - startPos.x);
						
						if (swipeValue > 0)//right swipe
							
							//MoveRight ();
						
						else if (swipeValue < 0)//left swipe
							
							//MoveLeft ();
						
					}
				break;
			}
		}
	}
}

Hu guys, I wrote this simple tutorial wich is basically 7 lines of code and works like a charm. Easy and simple. You just have to use te build in Unity event system instead to write long and useless code.
No need to use update or fixed update.

I found this post RTV Studios: Detecting swipe from Unity3D c# scripts

It detects swipe in four direction and we can also control the swipe speed and angle for the swipe in four direction.

Very cheap solution for beginners and experts who don’t want to spend much time in coding swipe & touch controls.
NOW with Playmaker support.

(Easy Swipe & Touch Controller)

Use the SwipeManager from the Unity forum:
