Player click event got triggered when non player is clicked

Questions & Answers
1

So i have 2 script, the first script is just a player script, the second script is to generate the map, when i click the player, the log showed up, when i click the map, the log showed up, but when i clicked on nothing (area outside the map), log not showed up (which is good), so what i want is only by clicking the player the log showed up.

TileMap Script
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class TileMap : MonoBehaviour {
	
    public TileType[] tileTypes;
    int[,] tiles;

    int mapSizeX = 10;
    int mapSizeZ = 10;

    // Use this for initialization
    void Start()
    {
        //Allocate the tiles of the map
        tiles = new int[mapSizeX, mapSizeZ];

        //Create the map
        CreateMap();

        //Generate the map
        GenerateMap();
    }
	
    void GenerateMap()
    {
        for (int x = 0; x < mapSizeX; x++)
        {
            for (int z = 0; z < mapSizeZ; z++)
            {
                TileType tt = tileTypes[tiles[x, z]];
                Instantiate(tt.tileVisualPrefab, new Vector3(x, 0, z), Quaternion.identity);
            }
        }    
    }    

    void CreateMap()
    {
        //Create the map based on the tiles
        for (int x = 0; x < mapSizeX; x++)
        {
            for (int z = 0; z < mapSizeZ; z++)
            {
                tiles[x, z] = 0;
            }
        } 
        //Create the road
        tiles[4, 2] = 1;
        tiles[4, 3] = 1;
        tiles[4, 4] = 1;
        tiles[5, 4] = 1;
        tiles[6, 4] = 1;
        tiles[7, 4] = 1;
        tiles[3, 4] = 1;
        tiles[2, 4] = 1;
        tiles[1, 4] = 1;

        //Create entry/ exit point
        tiles[4, 1] = 3;
    }
    // Update is called once per frame
    void Update()
    {
        
    }
}

and the player script (player got capsule collider and the script attached)

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerScript : MonoBehaviour
{
    public static bool isClicked;

	// Use this for initialization
	void Start ()
        {	
	
	}
	
	// Update is called once per frame
	void Update ()
    {
        if (Input.GetMouseButtonDown(0))
        {
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            RaycastHit hit;
            if (Physics.Raycast(ray, out hit))
            {
                isClicked = true;
                Debug.Log("Player CLicked");
            }
        }
    }
}

You will need to check the game object tags in the if: raycasting hits everything with a raycaster component. It does not differentiate what kind of game object it is, so you need to tell it to check the tags of a game object, and if the tag is the same as the tag you have on the player game object, only then should you execute some function.
