not sure what I’m missing so got character taking damage and the print statements come up just fine when hit 80-60-40-20-0 (dead) etc but my health bar when I take the first hit it just instantly drops to 0.

heres the code I’m using any help would be amazing.

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

public class DamageScript : MonoBehaviour {
public int currentHealth = 100;
public int maxHealth = 100;
int damage = 20;
public Image currentHealthBar;
public Text ratioText;

void Start()
{
	maxHealth = 100;
	currentHealth = maxHealth;
	UpdateHealthbar ();
}
public void UpdateHealthbar()
{
	int ratio = currentHealth / maxHealth;
	currentHealthBar.rectTransform.localScale = new Vector3 (ratio, 1, 1);
	ratioText.text = (ratio * 100).ToString ("0") + '%';
}
void OnCollisionEnter (Collision col)
{
	if (col.gameObject.tag == "Bullet") {
		currentHealth -= damage;
		print ("hurt" + currentHealth);
		if (currentHealth <= 0)
			Destroy (gameObject);
		{
			UpdateHealthbar ();

		
	} if (col.gameObject.tag == "Enemy") {
		currentHealth -= damage;
		UpdateHealthbar ();
		print ("hurt" + currentHealth);
		if (currentHealth <= 0)
			Destroy (gameObject);
	}
	
}

}
}

@justinkatic Use float for ratio, using an int and dividing will give you integer values rounded to the lower integer number.
For example : int ratio = 80/100 will be 0.

 public void UpdateHealthbar()
 {
     float ratio = currentHealth / maxHealth;
     currentHealthBar.rectTransform.localScale = new Vector3 (ratio, 1, 1);
     ratioText.text = (ratio * 100).ToString ("0") + '%';
 }

Change UpdateHealthBar script to this.
