hello all, im trying to make a health system for my game, te players runs with this script:

public int maxHealth;
public int currentHealth;

	void Start ()
	{
		currentHealth = maxHealth;
	}
	public void TakeDamage (int amount)
	{
		currentHealth -= amount;
	}

and i have a lazer prefab, with a script that handles the colision with the players and calls for the “take damage function”

	public int baseDamage;
	GameObject player;

	void Start()
	{
		player = GameObject.FindGameObjectWithTag("Player");
	}
	void OnTriggerEnter (Collider other)
	{
	       if (other.gameObject == player) 
		{
			HealthSystem.TakeDamage (baseDamage);
		}
	}
}

i tryied to make it static, but it didn’t help.

thanks in advance

From what I understand, you want to reference the player’s HealthSystem component.

Try this :

 public int baseDamage;
 GameObject player;
 HealthSystem healthSystem;

 void Start()
 {
     player = GameObject.FindGameObjectWithTag("Player");
     healthSystem = player.GetComponent<HealthSystem>();
 }
 void OnTriggerEnter (Collider other)
 {
        if (other.gameObject == player) 
     {
         healthSystem.TakeDamage (baseDamage);
     }
 }

}

i tryied that and didnt work, anyway after some more changes i finally make it work:

	public int baseDamage;
	GameObject disparo;

	void OnTriggerEnter (Collider other)
	{
		if (other.tag == "Player") 
		{
			HealthSystem healthRef = other.GetComponent<HealthSystem> ();
			healthRef.TakeDamage (baseDamage);
			Destroy (gameObject);
		}
	}

thank you @UnityCoach for pointing me in the right direction, that was really helpful.
