Damage range for grenade action

I was intrigued by your comment about creating a damage range for the grenade. Here is my solution:

if(collider.TryGetComponent<Unit>(out Unit targetUnit))
{
        float damageDistance =
                 Vector3.Distance(collider.transform.position, _targetPosition) /  DAMAGE_RADIUS;

        int rangedDamage =  Mathf.RoundToInt(Mathf.Lerp(30f, 20f, damageDistance) ;

        targetUnit.Damage(rangedDamage);

        Debug.Log(rangedDamage);
}

When the grenade lands on the same grid position as the unit the unit receives the max damage but units farther away but within range receive less.

Great job!
Only change I would make would be rename “damageDistance” to “damageDistanceNormalized” since that variable is storing the normalized distance instead of distance in world units.

Oh, I also implemented damage based on distance

    private int CalculateDamageBasedOnDistance(Vector3 explosionPosition, Vector3 victimPosition)
    {
        var distFromGroundZero = Vector3.Distance(victimPosition, explosionPosition);
        var damage = _maxDamage - Mathf.RoundToInt(_maxDamage * (distFromGroundZero / _blastRadius));
        return damage;
    }

Your use of the Lerp is clever, though. Well done
