how can i do it ??
: in some other script there is this line -

 if (!rect_inventory.Contains( new Vector2(Input.mousePosition.x, Screen.height - Input.mousePosition.y + 1))) {

i wanna replace input.mousePosition.x with finperPos.x

Uhm you declare fingerPos within the FingerGesture_OnFingerTap function so it can only be used within that function. I don’t know if you still can get this variable via the GetComponent thing, but I don’t think so.

You need to store the fingerPos in a new variable… So just declare a Vector2 fingerPos2; variable above where the other variables are (line 17-25) and then within your FingerGesture function you need to add “fingerPos2 = fingerPos”.

With that little change you can access the variable outside your script (optional add a variable that holds the script so it works faster, getComponent isa bit slower as i remember) via gameObject.GetComponent().fingerPos2.

Just to be clear, you’ll have to declare fingerPos2 to be public if you want to access it from other scripts:

 public Vector2 fingerPos2;

Yeah ofc, just forgot to write that, thanks mate :slight_smile:

You want to register the other script to the FingerTap event:

        void OnEnable()
        {
                FingerGestures.OnFingerTap += FingerGestures_OnFingerTap;
        }
 
        void OnDisable()
        {
                FingerGestures.OnFingerTap -= FingerGestures_OnFingerTap;
        }
 
        void FingerGestures_OnFingerTap( int fingerIndex,  Vector2 fingerPos, int tapCount )
        {
                //HAVE FUN HERE!
        }
