Kill script on collision when lives are lost

Hi, I just started studying Unity at TAFE and need help, I have a player that has 5 lives in a 2D game… and I have a ground with a kill script in it which on collision reduces the players life by 5 therefore killing the player, however if the player does not have exactly 5 lives left it won’t die on collision, and I cannot for life of me work out what it is i need to do to make my character with lives of 1, 2, 3 or 4 left to get them to activate the collision, here is the code, do i need an array not sure how to implement it …

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

public class GroundKill : MonoBehaviour {

void OnCollisionEnter2D(Collision2D col)
{ -= 5;



Before someone can Answer this for sure, he/she also needs to see the Script where the Number of current player Lives is stored. Because I can’t see this Script anywhere in this Question, I must assume what you could’ve done wrong.

I assume, that in the GameControlScript is a Update() Method, and Part of this Update() Method says something along the Lines of:

    if (health = 0)
        //Kill Code goes here

But you should Replace the = from if (health = 0)
with a =<.

if (health = 0) //If Health is equal 0 only Cares, if health is exactly 0. It doesn’t Care, if it’s higher or lower than 0,
but when it’s if (health =< 0) //If Health is equal or less than 0, this Part of the Code also does it’s Commands, if the Player has less than 0 health.

Whenever you’re dealing with Health in Programming, please Keep in Mind, that the Health (or any Numerical Variable) can Sink below 0, so you need to Build the Code in a Way, that accounts for it.

Again, I could not answer this for sure because of Missing Information, but this eventually happens anyone, and I hope I was able to help you with this Answer.
