Questions & Answers
1

So i have a button and it can be clicked from anywhere. My question is how can I make it clickable when player is in range like 1 meter or something. Here is my script :
using UnityEngine;
using UnityEngine.UI;
using System.Collections;

 public class ButtonOnClickActive : MonoBehaviour {
 
     public GameObject canvas;
     public AudioClip search;


    private bool clicked;

    void OnMouseOver()
   {
       if(Input.GetMouseButtonDown(0) && !clicked)
      {
          canvas.SetActive(true);
          clicked = true ;
          this.GetComponent<AudioSource>().Play();
          GetComponent<Renderer>().material.color = Color.red;
      }             
   }
 }

Change the if statement to include a distance check.

Example :

if (Input.GetMouseButtonDown(0) && !clicked && Vector3.Distance(transform.position, player.transform.position) < 1f)
{
    //do stuff
}
