My health decreases to fast.

Questions & Answers

I want it where if I stand in the trigger than my health will go down slowly, but I don’t know how to make it go slowly. I used a int value to make it a little slower which didn’t really slow it down much, so I tried a float value, but it says that I cannot use a float value. Somebody help. Heres my code. It’s line 52 where I’m having the problem.

using UnityEngine;
using System.Collections;

public class Soldier : MonoBehaviour {

	public int health = 100;
	public int hitSpeed = 1;
	public GUIText healthText;
	public GUIText dead;
	public bool canPickUpHealth;
	public bool isHit = false;
	public bool isDead = false;



	// Use this for initialization
	void Start () {
		SetHealthText();
		dead.text = "";
		canPickUpHealth = false;
		isDead = false;
	}
	
	// Update is called once per frame
	void Update () {
		if(health >= 100)
		{
			health = 100;
			SetHealthText();
		}
		if(health < 0)
		{
			health = 0;
			SetHealthText();
		}
		if(health <= 0)
		{
			Time.timeScale = 0;
			dead.text = "YOU ARE DEAD";
			SetHealthText();
		}
		if(health == 100)
		{
			canPickUpHealth = false;
		}
		else
		{
			canPickUpHealth = true;
		}
		if(isHit)
		{
			health -= 15 * hitSpeed;
			SetHealthText();
		}
		else
		{
			isHit = false;
		}



	
	}

	void OnTriggerEnter(Collider other)
	{
		if(canPickUpHealth)
		{
			if(other.gameObject.tag == "Health" && health <= 100)
		   {
				other.gameObject.SetActive(false);
			    health = health + 15;
				SetHealthText();
		   }
		}
		if(other.gameObject.tag == "Enemy" && health > 0)
		{
			isHit = true;
		}

	}

	void OnTriggerStay(Collider other)
	{
		if(other.gameObject.tag == "Enemy")
		{
			isHit = false;
		}
	}

	void OnTriggerExit(Collider other)
	{
		if(other.gameObject.tag == "Enemy")
		{
			isHit = false;
		}
	}

	void SetHealthText()
	{
		healthText.text = "Health: " + health.ToString();
		if(health <= 0)
		{
			dead.text = "YOU ARE DEAD";
		}
	}
	
}

first, change the declaration of health and hitSpeed to float. It tells you, that you can’t use float, because you can’t multiply int with float.

public float health = 100.0f;
public float hitSpeed = 1.0f;

then change the line where the health shoud go down

 health -= Time.deltaTime * hitSpeed;

And then you adjust the speed with the hitSpeed attribute…
