Unity Engine

I want to detect tap and swipe left and right. But I have problem about tap. When swipe it’s must tap it’s error.

this is code.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MobileController : MonoBehaviour {

    private bool tap, swipeLeft, swipeRight, swipeUp, swipeDown;
    private bool isDraging = false;
    private Vector2 startTouch, swipeDelta;

    private void Update()
    {
        tap = swipeLeft = swipeRight = swipeUp = swipeDown = false;

        #region Standalone Inputs

            if(Input.GetMouseButtonDown(0))
            {
                tap = true;
                isDraging = true;
                startTouch = Input.mousePosition;
            }
            else if(Input.GetMouseButtonUp(0))
            {
                isDraging = false;
                Reset();
            }

        #endregion

        #region Mobile Input

            if(Input.touches.Length > 0)
            {
                if(Input.touches[0].phase == TouchPhase.Began)
                {
                    tap = true;
                    isDraging = true;
                    startTouch = Input.touches[0].position;
                }
                else if(Input.touches[0].phase == TouchPhase.Ended || Input.touches[0].phase == TouchPhase.Canceled)
                {
                    isDraging = false;
                    Reset();
                }
            }

        #endregion

            {

            {
                swipeDelta = (Vector2) Input.mousePosition - startTouch;
            }
        }

        // Did we cross the deadzone ?
        if(swipeDelta.magnitude > 100f)

Your code blindly assumes that as soon as their finger touches the screen that it’s a tap. You’ll want to wait a little bit and see if the finger moves over the next few frames before assuming it’s a tap.
