Destroy player when slider gets <= 0

Questions & Answers

Hi!

I am trying to destroy the player when the player slider gets to <= 0 (currentHealth).

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class PlayerHealthSilderScript : MonoBehaviour {

	public ModeManager dead;
	
	public static float currentHealth;
	public static float maxHealth;
	
	public Slider playerHealthSlider;
	
	// Use this for initialization
	void Start () {
		currentHealth = 10f;
		maxHealth = 10f;
	}
	
	// Update is called once per frame
	void Update () {
		playerHealthSlider.value = calculateHealth();
		
		if(currentHealth <= 0f){
			dead.DestroyChild();
		}
	}
	
	float calculateHealth(){
		return currentHealth / maxHealth;
	}
	
	public void TakeDamage(){
		currentHealth--;
	}
}

I am trying to use the method DestroyChild() in my ModeManager script.

using UnityEngine;
using System.Collections;

public class ModeManager : MonoBehaviour {

	
	public void YellowMode(){
		// Instantiate PlayerYellow
		DestroyChild();
		GameObject playerYellow = Instantiate(Resources.Load ("PlayerYellow")) as GameObject;
		playerYellow.transform.SetParent (GameObject.FindGameObjectWithTag("Player").transform, true);
	}
	
	public void RedMode(){
		// Instantiate PlayerRed
		DestroyChild();
		GameObject playerRed = Instantiate(Resources.Load ("PlayerRed")) as GameObject;
		playerRed.transform.SetParent (GameObject.FindGameObjectWithTag("Player").transform, true);
	}
	
	public void BlueMode(){
		// Instantiate PlayerBlue
		DestroyChild();
		GameObject playerBlue = Instantiate(Resources.Load ("PlayerBlue")) as GameObject;
		playerBlue.transform.SetParent (GameObject.FindGameObjectWithTag("Player").transform, true);
	}
	
	public void GreenMode(){
		// Instantiate PlayerGreen
		DestroyChild();
		GameObject playerGreen = Instantiate(Resources.Load ("PlayerGreen")) as GameObject;
		playerGreen.transform.SetParent (GameObject.FindGameObjectWithTag("Player").transform, true);
	}
	
	public void GreyMode(){
		// Instantiate PlayerGrey
		DestroyChild();
		GameObject playerGrey = Instantiate(Resources.Load ("PlayerGrey")) as GameObject;
		playerGrey.transform.SetParent (GameObject.FindGameObjectWithTag("Player").transform, true);
	}
	
	public void PurpleMode(){
		// Instantiate PlayerPurple
		DestroyChild();
		GameObject playerPurple = Instantiate(Resources.Load ("PlayerPurple")) as GameObject;
		playerPurple.transform.SetParent (GameObject.FindGameObjectWithTag("Player").transform, true);
	}

	
	public void DestroyChild(){
		foreach(Transform child in transform){
			Destroy (child.gameObject);
			Debug.Log("Boom");
		}
	}
}

The method is not being called.
I tried to call a method in my PlayerController with DestroyPlayer() instead.

using UnityEngine;
using UnityEngine.UI;
using System.Collections;

public class PlayerController : MonoBehaviour {

	public GameObject bullet;
	public float bulletSpeed;
	
	void Update () {

		if(Input.GetKeyDown(KeyCode.Space)){
			GameObject playerBullet = Instantiate(bullet, transform.position, Quaternion.identity) as GameObject;
			playerBullet.rigidbody2D.velocity = new Vector3(0,bulletSpeed,0);
			playerBullet.transform.parent = transform;
		}
	}
	
	public void DestroyPlayer(){
		Destroy(gameObject);
	}
}

But when I do that, I get the “Destroying assets is not permitted to avoid data loss.” Error.

How could I do this?

Oh and the player spawns from this

using UnityEngine;
using System.Collections;

public class CreatePlayer : MonoBehaviour {

	
	// Use this for initialization
	void Awake () {
		
		GameObject slider = Instantiate(Resources.Load("PlayerHealthSlider")) as GameObject;
		slider.transform.SetParent (GameObject.FindGameObjectWithTag("Canvas").transform, false);
		
		
		GameObject player = Instantiate(Resources.Load ("PlayerYellow")) as GameObject;
		player.transform.SetParent (GameObject.FindGameObjectWithTag("Player").transform, true);
	}
	
	// Update is called once per frame
	void Update () {
	
	}
}

Edit the DestroyChild() to this

foreach(Transform child in GetComponentsInChildren<Transform>()){
			Destroy (child.gameObject);
			Debug.Log("Boom");
		}
