swipe manager sometime ignore swipe ?
Hi everyone! i have a little problem with a pretty good swipe manager i have found here : https://forum.unity.com/threads/swipe-in-all-directions-touch-and-mouse.165416/page-2
it take tap and swipe on both mouse and finger.
sometime (maybe 1 on 30 swipe or tap) unity ignore my swipe or my tap for 1 or two second maybe it's realy strange ... the game is realy playable (it's a plateformer) but sometime i want to do something i tap i swipe and ... nothings happend.
heres the code of the swipemanager i use :
using UnityEngine;
using System.Collections.Generic;
using System.Linq;
using UnityEngine.EventSystems;
class CardinalDirection
{
public static readonly Vector2 Up = new Vector2(0, 1);
public static readonly Vector2 Down = new Vector2(0, -1);
public static readonly Vector2 Right = new Vector2(1, 0);
public static readonly Vector2 Left = new Vector2(-1, 0);
public static readonly Vector2 UpRight = new Vector2(1, 1);
public static readonly Vector2 UpLeft = new Vector2(-1, 1);
public static readonly Vector2 DownRight = new Vector2(1, -1);
public static readonly Vector2 DownLeft = new Vector2(-1, -1);
public static readonly Vector2 Tap = new Vector2(0, 0);
}

this code is a component of my player and i implement it inside my player's script like that :
public void Start()
{
SwipeManager.OnSwipeDetected += OnSwipeDetected;
}
void OnSwipeDetected(Swipe direction, Vector2 swipeVelocity)
{
currentSwipeDir = direction;
}
public void Update()
{
if (SwipeManager.IsSwipingUp() )
{
/// do something
}
}
I know this could be difficult to answer but if someone know were i made a mistake it would be great to help because i have search by myself and i dont have any clue.
thanks for all !
hi ! No idea ? :)
