How to Move rigidbody2D on touch ?

Questions & Answers

Hi all,
I have done on touch to move object anywhere on screen. But my requirement is to just touch particular object and move on. Any help please ??
This is my code:

if (Input.touchCount > 0 && Input.GetTouch (0).phase == TouchPhase.Moved) {
						Vector2 touchdeltaposition = Input.GetTouch (0).deltaPosition; 
						anglex = (float)(touchdeltaposition.x * Time.deltaTime * 10.0); 
						angley = (float)(touchdeltaposition.y * Time.deltaTime * 10.0);
						elevationAngle = new Vector3 (anglex, angley, 0);
						Vector3 elevation = Quaternion.Euler (elevationAngle) * transform.forward;
						rigidbody2D.AddForce (elevation/2);
						rigidbody2D.velocity = new Vector2 (anglex, angley);
				}

In my 2d Platformer (Unity 4.3) I had 3 scripts for left & right movement. One was Player.cs (Player Raycasting, Left and right movement, etc), MoveLeft.cs and Move Right.cs.

With Player.cs I had a setup Like this (Attached to Player)

using UnityEngine;
using System.Collections;

public class Player : MonoBehaviour {

	public float PlayerMoveSpeed = 3f;
	public static bool PlayerMoveRight = false;
	public static bool PlayerMoveLeft = false;
	// Use this for initialization
	void Update()
	{
		//Run these to functions
		Movement();
	}

void Movement()
	{
		//Touch Controls

		if(MoveRight == true)
		{
			transform.Translate(Vector2.right * PlayerMoveSpeed * Time.deltaTime);
			transform.eulerAngles = new Vector2(0, 0);
		}
            //Left Movement triggered
		if(MoveLeft == true)
		{
			transform.Translate(Vector2.right * PlayerMoveSpeed * Time.deltaTime);
			transform.eulerAngles = new Vector2(0, 180);  
		}
        }
   }

The variables MoveLeft & MoveRight would be set to true/false with these scripts…

MoveLeft.cs… For Left movement on touch (Attach to guiTexture Called MoveLeft)

using UnityEngine;
using System.Collections;

public class MoveLeft : MonoBehaviour {
	
	// Update is called once per frame
	void Update () 
	{
		//Is there a touch?
		if(Input.touches.Length <= 0)
		{
			//If no touches...
		}
		else //If screen touched..
		{
			//Loop through these
			for(int i = 0; i < Input.touchCount; i++)
			{ 
				//executes this code for current touch
				if(this.guiTexture.HitTest(Input.GetTouch(i).position))
				{
					//If current touch hits the guitexture...

//MoveRight bool within PlayerLogic = false when touch has Began				if(Input.GetTouch(i).phase == TouchPhase.Began)
					{  
						Player.PlayerMoveLeft = true;
					}
//MoveLeft bool within PlayerLogic = false when touch has ended					if(Input.GetTouch(i).phase == TouchPhase.Ended)
					{
					Player.PlayerMoveLeft = false;
					}
				}
			}
		}
	}
}

MoveRight.cs… For Left movement on touch (Attach to guiTexture Called MoveRight)

using UnityEngine;
using System.Collections;

public class MoveRight : MonoBehaviour {

	// Update is called once per frame
	void Update () 
	{
		//Is there a touch?
		if(Input.touches.Length <= 0)
		{
			//If no touches...
		}
		else //If screen touched..
		{
			//Loop through these
			for(int i = 0; i < Input.touchCount; i++)
			{ 
				//executes this code for current touch
				if(this.guiTexture.HitTest(Input.GetTouch(i).position))
				{
					//If current touch hits the guitexture...
					if(Input.GetTouch(i).phase ==  TouchPhase.Began)
					{ 
						Player.PlayerMoveRight = true;
					}
					if(Input.GetTouch(i).phase == TouchPhase.Ended)
					{
						Player.PlayerMoveRight = false;
					}
				}
			}
		}
	}
}
