using UnityEngine;

public class example : MonoBehaviour
{
    void Update()
    {
        // Left-half of the screen.
        Rect bounds = new Rect(0, 0, Screen.width/2, Screen.height);
        if (Input.GetMouseButtonDown(0) && bounds.Contains(Input.mousePosition))
        {
            Debug.Log("Left!");
