Ontouch Destroy BoxCollider2D

Questions & Answers

I’ve tried the following codes but it doesn’t seem to work on my android device and on ios simulator.

function Update(){
     if(Input.touchCount > 0){
	    if(Input.GetTouch(0).phase == TouchPhase.Began){
	    var x = checkTouch(Input.GetTouch(0).position);
	    }
     }
}

function checkTouch(pos){
    var wp : Vector3 = Camera.main.ScreenToWorldPoint(pos);
    var touchPos : Vector2 = new Vector2(wp.x, wp.y);
    var hit = Physics2D.OverlapPoint(touchPos);
    if(hit){
    //destroy my object
    //return something
    }
}

Touch is detected but something seems to be wrong with the function checkTouch() line1 - line 3. However, when i am using the code in update() function:

if(Input.GetMouseButtonDown(0)) {
	   var x = checkTouch(Input.mousePosition);
}

The checkTouch() function works nicely, the object is destroyed.

Anyone can help or provide me with a solution?

Thanks in advance.

Non functional code: (touch is detected but overlappoint not working)

function Update(){
     if(Input.touchCount > 0){
        if(Input.GetTouch(0).phase == TouchPhase.Began){
        var x = checkTouch(Input.GetTouch(0).position);
        }
     }
}
 
function checkTouch(pos){
    var wp : Vector3 = Camera.main.ScreenToWorldPoint(pos);
    var touchPos : Vector2 = new Vector2(wp.x, wp.y);
    var hit = Physics2D.OverlapPoint(touchPos);
    if(hit){
    //destroy my object
    //return something
    }
}

Working code: (detecting mouse click)

 function Update(){
         if(Input.GetMouseButtonDown(0)) {
                var x = checkTouch(Input.mousePosition);
         }
    }
     
    function checkTouch(pos){
        var wp : Vector3 = Camera.main.ScreenToWorldPoint(pos);
        var touchPos : Vector2 = new Vector2(wp.x, wp.y);
        var hit = Physics2D.OverlapPoint(touchPos);
        if(hit){
        //destroy my object
        //return something
        }
    }
