How can you tread 2 objects with the same tags and script as different objects?

Unity Engine

Hello,

I used to work with Unity but now I did not use it for a while, and I kinda forget some things how it worked :frowning:

I am making a 2D game for iOS and Android and you have to drag pawns around the playing board.

Now I wrote a script that works perfectly for 1 pawn, but if I add other pawns they will all move at the same time. Even though I am raycasting which pawn is touched, and only moving the “this” object.

Here you can see my script, it is added to all the pawns, and now they all move, but i want only to move the one i touched…

public var speed:int = 17;
private var x:float;
private var y:float;

private var hit: RaycastHit;

public var pawnSelected:boolean = false;

function Update () {
	for (var touch : Touch in Input.touches) {
    	// and only if the touch moved since last update
    	var ray = Camera.main.ScreenPointToRay (touch.position);
		var hit : RaycastHit;
		
		if(touch.phase == TouchPhase.Began  Physics.Raycast(ray, hit)) {
			if(hit.collider.gameObject.tag == "Pawn"){
				pawnSelected = true;
 			}		
		}   
		
		if(Input.touchCount > 0){  // Only work with the first touch
         	
        	if(Input.touchCount == 1)
			{
		    	if (Input.touches[0].phase == TouchPhase.Moved)
		       	{
		       		if(pawnSelected){
			        	x = Input.touches[0].deltaPosition.x * speed * Time.deltaTime;
			        	y = Input.touches[0].deltaPosition.y * speed * Time.deltaTime;
			        	this.transform.Translate(new Vector3(x, 0, y));
			        }
		        }
		   	}	    	
        }
        if(touch.phase == TouchPhase.Ended ) {
			if(pawnSelected){
				pawnSelected = false;
 			}		
		}
		
	}
}

This is because you never check to see if your “touch” actually is on the pawn. You simply jump right in and start pushing pawns around. This will affect all of them since nothing stops that from happening.
