AnimationEvent NullReferenceException

Questions & Answers
1

I was working on a script to add an animation to a weapon, and when I added the animation event to the timeline I started to randomly get this error “NullReferenceException: Object reference not set to an instance of an object
Melee.AttackDamage () (at Assets/Scripts/Melee.js:28)” Everything else works fine, but the minute I try to add the Event I get the error. It doesn’t affect the game, but I’m still wondering why it happens.

#pragma strict

var TheDamage : int = 50;
var Distance : float;			
var MaxDistance : float = 1.5; 
var TheSystem : Transform; 


function Update ()								 
{
	if(Input.GetButtonDown("Fire1")) 
	{
		
		animation.Play("Attack"); 
	}

}

function AttackDamage () 
{
	var hit : RaycastHit; 
	if(Physics.Raycast (TheSystem.transform.position, TheSystem.transform.TransformDirection(Vector3.forward),hit))
	{											 
		Distance = hit.distance; 
	}		
	if (Distance < MaxDistance)
	{ 										
		hit.transform.SendMessage("ApplyDamage", TheDamage, SendMessageOptions.DontRequireReceiver);
		
	}
}

#pragma strict

var Health = 100;

function Update ()
{
	if (Health <= 0)
	{
		Dead ();
	}
}

function ApplyDamage (TheDamage: int)
{
	Health -= TheDamage;
}

function Dead ()
{
	Destroy (gameObject);
}

Alright I think I fixed it. I don’t think I’ll be using send message again if I’m able. Basically just had the if statement call a static function.

var TheDamage : int = 50;
var Distance : float;			
var MaxDistance : float = 1.5; 
var TheSystem : Transform;



function Update ()								 
{
	if(Input.GetButtonDown("Fire1")) 
	{
		
		animation.Play("Attack"); 
	}

}

function AttackDamage () 
{
	var hit : RaycastHit;
	if(Physics.Raycast (TheSystem.transform.position, TheSystem.transform.TransformDirection(Vector3.forward),hit))
	{											 
		Distance = hit.distance; 
	}		
	if (Distance < MaxDistance)
	{ 										
		EnemyLogic.ApplyDamage(TheDamage);
	}
}

#pragma strict

static var Health = 100;

function Update ()
{
	if (Health <= 0)
	{
		Dead ();
	}
}

static function ApplyDamage (TheDamage: int)
{
	Health -= TheDamage;
}

function Dead ()
{
	Destroy (gameObject);
}
