How to fix my Life counter

Questions & Answers
1

I’m attempting to add a life counter to the UFO tutorial game. Ideally, whenever the UFO hits an enemy square, the life points are deducted by one. The problem I am currently having is that the counter for my lives is mimicking the counter that tracks the pickups. I would appreciate any insight!

public class PlayerControl : MonoBehaviour
{

public float speed; 

public Text countText;
public Text livesText;

public Text winText;
public Text winText2;
public Text winText3;
public Text loseText;

private Rigidbody2D rb2d;      
private int count;
private int lives;


void Start()
{
    rb2d = GetComponent<Rigidbody2D>();

    count = 0;
    lives = 0;

    winText.text = "";
    winText2.text = "";
    winText3.text = "";
    loseText.text = "";

    SetLivesText();

    SetCountText();
}

void FixedUpdate()
{
    float moveHorizontal = Input.GetAxis("Horizontal");
    float moveVertical = Input.GetAxis("Vertical");

    Vector2 movement = new Vector2(moveHorizontal, moveVertical);
    rb2d.AddForce(movement * speed);

    if (lives == 0)
    {
        SetLivesText();
    }

    if (Input.GetKey("escape"))
    {
        Application.Quit();
    }
       
}

void OnTriggerEnter2D(Collider2D other)
{
    if (other.gameObject.CompareTag("Pentagon"))
    {
        other.gameObject.SetActive(false);
        count = count + 1;
        SetCountText();
    }

    if(other.gameObject.CompareTag("Enemy"))
    {
        lives--;
        SetLivesText();
    }

       
}

void SetLivesText()
{
    livesText.text = "Lives: " + count.ToString();
   
    if (lives == 0)
    {
        loseText.text = "You have lost the game! Better luck next time!";
    }
}

void SetCountText()
{
    countText.text = "Count: " + count.ToString();
    

    if (count >= 8)
    {
        winText.text = "Congragulations! You Win!";
        winText2.text = "Game created by ";
        winText3.text = "Challenge 1: UFO";
    }
   
}

}

You are initializing the ‘lives’ variable with zero, but I believe you want to start out with a number of lives, e.g. 3. The rest looks alright from a quick glance. Are you having other specific issues? Are the references in the inspector pointing to the text components for score and lives correct? Sometimes its easy to accidentally have both variables reference the same text or other mixups.
