Damage Dropoff

i figured out how to do it :) here's the script:

     private float distancePercent;
 
     public LayerMask whatToHit;
     private float distance;
     private float clampedDistance;
     public float tempMaxDamage= 100;
     public float tempMinDamage= 10;
     public float realDamage;
     public float tempDamageDropStart =10;
     public float tempDamageDropEnd = 100;
 
     
 public void Start(){
     Vector2 thispos = new Vector2 (transform.position.x, transform.position.y);
     RaycastHit2D hit = Physics2D.Raycast (thispos,transform.right, 100, whatToHit);
     Debug.DrawLine (thispos, transform.right*100, Color.cyan);
     if (hit.collider != null) {
         Debug.DrawLine (thispos, hit.point, Color.red);
             distance = Vector2.Distance(thispos, hit.point);
             clampedDistance = Mathf.Clamp(distance,tempDamageDropStart,tempDamageDropEnd) - tempDamageDropStart;
             distancePercent = 100- clampedDistance* (100/(tempDamageDropEnd-tempDamageDropStart));
     realDamage = tempMinDamage +(tempMaxDamage - tempMinDamage)* (distancePercent/ 100);
 
             Debug.Log("We hit something and did"+realDamage+"damage");
 }
         

i put it on my bullet prefab and it works
