Destroy object after clicking button few times.

Question

I want to write a script that will destroy a tree when three is clicked 3 times but script is stopping on "hp = 3". Thank you for help.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class SCINANIE : MonoBehaviour

     public Animator animacja;
     public Animator anim;
     public Canvas text;
     public Canvas textno;
     private bool intree;
     public Canvas A, B, C, D;
     public GameObject axe, player, drzewo;
 
     // Use this for initialization
 
     void Start()
     {
         text.enabled = false;
         textno.enabled = false;

You are trying to check a keyPress while the method is only called once by the Invoke(), you'd need to press the key the exact moment when the invoke is happening right now.

You could fix this by giving the object a general HP value and decrease this with each mouseClick. You could also execute more code for each HP value in this way as well.

An example:

     if (Input.GetMouseButtonDown(0) && hp > 0){
         hp--;
     }
     
     switch(hp){
         case 0:
          // Death actions here
         break;
     
         case 1:
          // Actions here
         break;
     
         case 2:
          // Actions here
         break;
     
         //ETC.
     }

Or you could make a click counter and increment it each time the player presses the mousebutton at the object's position, like so:

 int clickCount = 0;
 
 if(Input.GetMouseButtonDown(0)){
  clickCount++;
 }
 
 if(clickCount >= 3){
  //Do stuff
 }

Destroy object after clicking button few times.
