Hey guys. In a combat system for a game I’m making, one script which contains the damage scripts sends a message to a health script, telling it to take the defense damage variable sent off of the defense total in the health script. If the defense is equal to or less than zero, a message is sent back to the damage script, which is supposed to, the next time an attack move is executed, send a message back to the health script which takes health damage off of the health total. See:

#pragma strict

var stabDamage : int = 500;
var stabDefenceDamage : int = 5;
var quickSwingDamage : int= 200;
var quickSwingDefenceDamage : int = 10;
var heavySwingDamage : int = 300;
var heavySwingDefenceDamage : int = 25;
var distance : float;
var maxDistance : float = 2.5;
var gladius : Transform;

function Update () {

if(Input.GetMouseButtonDown(0)){

	gladius.animation.Play("quickSwing");
	var hit1 : UnityEngine.RaycastHit;

		if(Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), hit1)){
 
 			distance = hit1.distance;
 
 				if( distance < maxDistance){
 					
 					 hit1.transform.SendMessage("AlterDefence", quickSwingDefenceDamage, SendMessageOptions.DontRequireReceiver);					
					 	

}
}
}

if(Input.GetMouseButtonDown(1)){

	gladius.animation.Play("heavySwing");
	var hit2 : UnityEngine.RaycastHit;

		if(Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), hit2)){
 
 			distance = hit2.distance;
 
 				if( distance < maxDistance){
 
					hit2.transform.SendMessage("ApplyDamage", heavySwingDamage, SendMessageOptions.DontRequireReceiver);
}
}
}

if(Input.GetButtonDown("stab")){

	gladius.animation.Play("stab");
	var hit3 : UnityEngine.RaycastHit;

		if(Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), hit3)){
 
 			distance = hit3.distance;
 
 				if( distance < maxDistance){
 
					 hit3.transform.SendMessage("ApplyDamage", stabDamage, SendMessageOptions.DontRequireReceiver);
}
}
}

if(gladius.animation.isPlaying == false){

	gladius.animation.CrossFade("Idle");
}
}

function QuickSwingDamage(){
	var hit1 : UnityEngine.RaycastHit;

		if(Physics.Raycast(transform.position, transform.TransformDirection(Vector3.forward), hit1)){
 
 			distance = hit1.distance;
 
 				if( distance < maxDistance){
 				
	hit1.transform.SendMessage("ApplyDamage", quickSwingDamage, SendMessageOptions.DontRequireReceiver);
		}
	}
}

and:

var health = 500;

var defence = 100.00;

var defenceModifier : int;

var evadeChance : int; 

function Update(){

		if(health <= 0){

			Dead();
	}
	
		if(defence <= 0){

			SendMessage("QuickSwingDamage", SendMessageOptions.DontRequireReceiver);
	}
}

function ApplyDamage(damage : int){

	health -= damage;
}

function AlterDefence(defenceDamage : int){

			defence -= defenceDamage;

}

function Dead(){

Destroy (gameObject);

Currently, nothing happens, in fact defense goes in to negative values instead of staying at 0 and enacting health damage to the health script values. I’m pretty new at using unity so it’s probably a little thing that I haven’t noticed. Thanks for the helps guys!

instead of making it less than or equal to 0, you could try just making it less than 1.

if(health < 1){
