I have 2D project and I want to be able move camera by touch to the right and back... I found one tutorial, moving camera with swipes so it is working fine but how can I set maximum distance to move camera?

using System.Collections;

using System.Collections.Generic;

using UnityEngine;



public class TouchController : MonoBehaviour

{

float touchStart = 0f;

Vector3 cameraDestination;

public float cameraSpeed = 0.1f;

Camera m_MainCamera;

// Use this for initialization

void Start()

{

    cameraDestination = Camera.main.transform.position;

}

// Update is called once per frame

void Update()

{

    if (Input.GetMouseButtonDown(0))

    {

        touchStart = Input.mousePosition.x;

    }

    if (Input.GetMouseButtonUp(0))

    {

        float delta = Input.mousePosition.x - touchStart;

        if (delta < -50f)

        {

            cameraDestination = new Vector3(Camera.main.transform.position.x + 500,

                Camera.main.transform.position.y, Camera.main.transform.position.z);

            // move the camera right

        }

        else if (delta > 50f){

            cameraDestination = new Vector3(Camera.main.transform.position.x - 500,

                Camera.main.transform.position.y, Camera.main.transform.position.z);

            // move the camera left

        }

    }

    if (Vector3.Distance(Camera.main.transform.position, cameraDestination) > 0.1f)

    {

        if (Camera.main.transform.position.x > cameraDestination.x)

        {

            Camera.main.transform.position = new Vector3(Camera.main.transform.position.x - cameraSpeed,

                Camera.main.transform.position.y, Camera.main.transform.position.z);

        }

        else

        {

            Camera.main.transform.position = new Vector3(Camera.main.transform.position.x + cameraSpeed,

                Camera.main.transform.position.y, Camera.main.transform.position.z);

        }

    }

}

}

Your question is unclear, but I assume you want to set a limit for the camera's position. For this you'll need 2 points - the minimum point (x = the smallest X value the camera is allowed to have, y = the smallest Y value the camera is allowed to have) and the maximum point (same thing but represents the upper bound).

Vector2 minPosition, maxPosition;

Then, every time you move your camera, check the following conditions and only then move it:

if (cameraDestination.x < maxPosition.x && cameraDestination.x > minPosition.x) //Ensures the camera's X value is within the allowed range

if (cameraDestination.y < maxPosition.y && cameraDestination.y > minPosition.y) //Ensures the camera's Y value is within the allowed range
