I made projectile that, when they hit a collider, spawn prefab.

That prefab contain a particle system, a light and a script i made, to animate the light.range.

Problem is every light that are spawned retain the light.range of the first spawned one.

Any way i could make it so that everytime the prefab spawned, the animation plays and kill the object ?

note: the curve variable is not set in script, i created it by hand in the inspector on the prefab.

    using UnityEngine;
    using System.Collections;
    
    public class DestroySelfOverTime : MonoBehaviour {
    	public AnimationCurve curve;
    	public float curveValue;
    	public float duration;
    	
    	// Use this for initialization
    	void Start () {
    	}
    	
    	// Update is called once per frame
    	void Update () {
        duration-=Time.deltaTime;
    	curveValue = curve.Evaluate(Time.deltaTime);
    	Debug.Log(curveValue);
    	light.range = curveValue;	
    
    	if(duration <=0){
    			
    	KillMyself();	
    		}
    	}
    	
    	void KillMyself(){
    		Debug.Log("BOOM");
    		Destroy(gameObject);
    	}	
    }

Your problem is with :

curveValue = curve.Evaluate(Time.deltaTime);

Change this to :

curveValue = curve.Evaluate(duration);

You want to evaluate the duration, this is already modified over time to give a value between duration(2.0f) and zero. Time.deltaTime will always evaluate around the same point of the curve (approx 0.016 secs). This should be confirmed by the value returned by Debug.Log(curveValue);
