Box Collider Technical Difficulties

Hello:
I'm very new to Unity and Javascript... I've had difficulties, but i always manage to get it to work... However, I am trying to have a Tank fire at an area that contains a Target... Which is now working perfectly, but what im trying to do is take the variable damage from the tank.. and applying that to any "enemies" in that area... My plan is to make a box collider and have that spawn at the target location, and SOMEHOW take the variable Damage from the UnitInfo script of the attacker, and applying that in the UnitInfo script of the receiever...

Code (JavaScript):

1. private var UnitInfoInstance : UnitInfo;
2. var Damage : float;
3.  
4.  
5. function Update () {
6.  
7. }
8.  
9. function OnCollisionEnter(collision : Collision)
10. {
11.     UnitInfoInstance = GetComponent(UnitInfo);
12.     var Damage = UnitInfoInstance.Damage;
13.     SendMessage("ApplyDamage", Damage);
14. }

 

use an OverlapSphere at the point of impact. then send the message to all enemies inside the sphere.

 

Thank you kind Sir,
I've researched it, and finally got a working function. Now my idea seems to work, for the most part... Problem is, when the Damage is applied, it's applied OVER and OVER in the same target... I want it to apply the damage once Per Target... Here is my code:

Code (JavaScript):

1.     var cols: Collider[] = Physics.OverlapSphere(Target.transform.position, DamageRadius);
2.  
3.     for (var col: Collider in cols)
4.     {
5.         var script: UnitInfo;
6.         script = col.GetComponent(UnitInfo);
7.         script.CurrentHealth -= UnitInfoInstance.Damage;
8.     }

** I'm pretty sure it has something to do with the for loop, i'll keep experimenting with it, maybe i get to something

 

Set your array to null after you have applied the damage to all the units

 

do you still have this snippet inside the projectile's OnCollisionEnter function? because then it should only do it once since the enter is only detected once.
