I’ve written a script that deducts lives every time that my object collides with a ball, however, the object does not get destroyed when it reaches 0 but, instead, has to be hit one more time at zero to be destroyed. I would like the object to be destroyed when the lives reach 0 and not have to be hit one more time. Here is my script:

using UnityEngine;
using System.Collections;

public class RedBase : MonoBehaviour {

void OnCollisionEnter (Collision col) {
	RedLives();
}

public void RedLives() {
	if(Lives.redCurLives > 0)
	Lives.redCurLives--;
	
	else {
		GameOver();
	}
}

public void GameOver() {
	Destroy(gameObject) ;
}

}

Change RedLives() to this:

public void RedLives() {
    if (Lives.redCurLives > 0)
	    Lives.redCurLives--;
 
    if (Lives.redCurLives == 0)
       GameOver();
}

After changing Lives.redCurLives you need to check if it hit zero.

public void RedLives() {
Lives.redCurLives–;

    if(Lives.redCurLives <= 0){
        Lives.redCurLives = 0;
        Destroy(gameObject)
    }
}

IMHO,
I used

if(Lives.redCurLives < 1)
{
GameOver()
}

and set the var to float.
