Hello;

I m trying to convert the project from Web to Android. Im using the camera with arrow keys, i m trying to touch the screen and go left right up and down.

Here is my code in Web:

 if (Input.GetKey(KeyCode.UpArrow) && Camera.main.transform.position.y < CameraYLimitUp)//Up Camera Mvt
            { transform.Translate(-Vector3.up * Time.deltaTime * 20); }
            
           if (Input.GetKey(KeyCode.DownArrow) && Camera.main.transform.position.y > CameraYLimitDown)//Down Camera Mvt
            { transform.Translate(Vector3.up * Time.deltaTime * 20); }

            if (Input.GetKey(KeyCode.LeftArrow) && Camera.main.transform.position.x > CameraXLimitLeft)//Left Camera Mvt
            { transform.Translate(Vector3.right * Time.deltaTime * 20); }

            if (Input.GetKey(KeyCode.RightArrow) && Camera.main.transform.position.x < CameraXLimitRight)//Right Camera Mvt
            { transform.Translate(Vector3.left * Time.deltaTime * 20); }

Thanks for your help

You could use Unity’s joystick mobile asset and script.

Something like this?

using UnityEngine;
using System.Collections;

public class Test : MonoBehaviour
{
	int CameraYLimit;
	Camera cam;

	void Start ()
	{
		cam = Camera.main;
		CameraYLimit = 10;
	}

	void Update ()
	{
		if(Input.touchCount > 0)
		{
			if(Input.GetTouch(0).deltaPosition.x > 0 && cam.transform.position.y < CameraYLimit)
				transform.Translate(-Vector3.up * Time.deltaTime * 20);
		}
	}
}

i find a solution for touching the screen in the left, right, up and down

        #region Touch Mobile

        if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved)
        {
            Vector2 touchDeltaPosition = Input.GetTouch(0).deltaPosition;
            transform.Translate(-touchDeltaPosition.x * speed * Time.deltaTime, -touchDeltaPosition.y * speed * Time.deltaTime, 0);

            Vector3 tmpPosX = transform.position;
            tmpPosX.x = Mathf.Clamp(tmpPosX.x, -13.0f, 14.0f);
            transform.position = tmpPosX;
            

            Vector3 tmpPosY = transform.position;
            tmpPosY.y = Mathf.Clamp(tmpPosY.y, -7.0f, 18.0f);
            transform.position = tmpPosY;
            
        }
        #endregion

this script let me move the camera when i touch the screen in the left , right , up and down and let me limit the movement of the camera in X and Y Axis.
