Hi id like to know how do I make an efficient code for this, i was thinking a for loop for every 250 damage taken, the enemy will instantiate a prefab. But in a noob to coding so if anyone can tell me how do I achieve this, would be a great help, thank you 
I would suggest using an event so that when each time damage is taken you can instantiate prefab.
A tutorial from unity: Events - Unity Learn
It’s really hard to help without the code you’ve made so far.
Here is how I would do it :
private int life ;
private int lifeThreshold = 250;
public void TakeDamage( int damages )
{
life -= damages ;
lifeThreshold -= damages ;
if( life <= 0 )
{
life = 0 ;
lifeThreshold = 0 ;
Die();
}
else if( lifeThreshold <= 0 )
{
while( lifeThreshold <= 0 )
lifeThreshold += 250 ;
// Instantiate your gameobject
}
}
hey watch this it’s very simple and nice.
you should have a healthManager script like this
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class healthManager : MonoBehaviour {
public int health;
public int itsTimeToInstantiate;
public GameObject bloodParticle;
// Use this for initialization
public void GiveDamage(int a){//we check this later
health-=a;
itsTimeToInstantiate += a;
if (itsTimeToInstantiate > 250) {
itsTimeToInstantiate = 0;
Instantiate (bloodParticle,transform.position,transform.rotation);
//instantiate blood
//now lets create a blood particle
}
}
}
and a spike like this
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class spike : MonoBehaviour {
void OnTriggerEnter2D(Collider2D other){
if (other.CompareTag ("player")) {
other.GetComponent<healthManager> ().GiveDamage (100);//so it will damage player 50 points
Destroy(gameObject);
}
}
}
it’s like the tutorial watch this it will help you :).

This is a script that performs each time we are damaged for 250 or more:
//The amount player is damaged before an event plays.
public float damageInterval = 250;
//The maxHealth of the player.
public float maxHealth = 1000;
//Amount of damage done to player using the hurt key.
public float hurtAmount = 100;
//Key in which when clicked hurts the player.
public KeyCode HurtKey = KeyCode.Q;
//HealthSlider on a canvas to mark how much health the player has.
public UnityEngine.UI.Slider healthSlider;
//The currentHealth reference of the player.
float currentHealth;
//This is used to get the damage the player needs
//to be damaged before an event plays.
float currentDamageInterval;
//This is a bool telling whether a critical is allowed or not.
bool criticalAllowed;
void Start () {
//Set criticalAllowed to false because we can not do a critical on start.
criticalAllowed = false;
//Set currentHealth to maxHealth.
currentHealth = maxHealth;
//The damage needed for an event to play. So it is (1000 - 250) currently.
currentDamageInterval = maxHealth - damageInterval;
//The amount needed for the first critical hit or whatever event you want.
Debug.Log("First Critical: " + currentDamageInterval);
//Sets the slider to have the maxHealth.
healthSlider.maxValue = maxHealth;
//Then sets its value to currentHealth.
healthSlider.value = currentHealth;
}
void Update () {
//If the hurt key is pressed.
if (Input.GetKeyDown(HurtKey))
{
//Then damage the player for the hurt amount.
TakeDamage(hurtAmount);
}
//If the players health does not equal our maxHealth
//and is not less than or equal to 0.
if (currentHealth != maxHealth && !(currentHealth <= 0))
{
//And our player's currentHealth is less than or equal to our damage interval.
if (currentHealth <= currentDamageInterval)
{
//You can play the event right here.
//I made one up it does a critical hit.
CriticalHit();
//Setup our damage interval for the next event.
//The first time this will be set as (750 - 250).
//The second time (500 - 250).
//And the last (250 - 250).
currentDamageInterval -= damageInterval;
//Say ouch because we want to know the event played.
Debug.Log("Ouch!");
//This tells you how much health we need for the next event.
Debug.Log("DamageTil Next Critical: " + currentDamageInterval);
}
}
}
void CriticalHit()
{
//This find a number between 0-10 that is needed for the critical to work.
int numberNeededForHit = Random.Range(0, 10);
//This will be a random guess between 0-10
int guessAtCriticalHitNumber = Random.Range(0, 10);
//If our random guess is equal to the number needed for the critical.
if (guessAtCriticalHitNumber == numberNeededForHit)
{
//Allow for the critical to be performed.
criticalAllowed = true;
}
else
{
//If our random guess is wrong say so.
Debug.Log("Our Critical Attack Failed!");
}
}
void TakeDamage(float DamageAmount)
{
//If our currentHealth less than or equal to 0.
if (currentHealth <= 0)
{
//Then set currentHealth equal to 0.
currentHealth = 0;
//Then return so nothing else happens from here.
return;
}
//If we can perform our critical.
if (criticalAllowed == true)
{
//This is our critical damage amount.
float CriticalDamageAmount = DamageAmount * 2;
//Subtract our health by our critical damage.
currentHealth -= CriticalDamageAmount;
//Then disallow for another critical because we just performed it.
criticalAllowed = false;
}
//If we do not have a critical.
if (criticalAllowed == false)
{
//Damage our player by the regular damage amount.
currentHealth -= DamageAmount;
}
//Set our slider to show our current health.
healthSlider.value = currentHealth;
}
